Following years of work, Dr. Vera Profit, professor of German and Comparative Literature, released her book “The Devil Next Door” on Aug. 8. Profit, who said the book explores the problem of evil, described her writing as an attempt to “help people live better and more efficient lives.”“The basic premise is how do you recognize an evil person?” she said. “Evil is hard to recognize. Evil is a progression, and we tend not to see the first, second, third steps, but the final.”Profit said she was inspired by M. Scott Peck’s book “People of the Lie.”“In 1984, I read ‘People of the Lie,’ which so changed the way I looked at life, that not only did I read the text, I read all the material that was listed in the footnotes because I wanted the complete context,” she said. “[Peck] can state complex ideas in a totally approachable manner.“This book was so fascinating that I couldn’t turn the pages fast enough. The book was about the hope for healing human evil. What he did was blend theology and science.”Profit said Peck’s book inspired her to teach a course on the subject.“I then created a course called Evil and the Lie in Modern European Prose right after reading this book,” she said. “It has always been extremely well received. You study goodness from the other side when you study evil. Because the course was so well received and many students told me it was a life-changing course, I decided to write the book after the course.”The book looks at the problem of individual evil for the most part, Profit said.“I took some of the questions that Peck raises, used his clinical experience, read copious amounts of ancillary material and formulated eight characteristics which define individual evil,” she said. “There are two types of evil – group and individual – which are both discreet and a blended phenomenon. I name the eight characteristics of evil and trace them though two novels, one written by a Swiss writer and one Oscar Wilde’s ‘The Picture of Dorian Grey.’ I also propose eight characteristics of group evil.”Profit said her book is meant to help other people.“I am trying to help other people not waste their life trying to reinvent the wheel,” she said. “We can learn a lot from other people’s examples. We can save ourselves and other people a lot of trouble.“Writing a book is a scary position because you have no control over how it will be received. You can give it your best shot and let it go. You have to do it despite your misgivings. The person who learns the most is not the person who reads the book, but the person who writes it. It was worth it to me because I learned so much. If it makes you look at life just a little differently than before, then it was worth it.”Tags: evil, M. Scott Peck, People of the Lie, The Devil Next Door, Vera Profit

(Visited 23 times, 1 visits today)FacebookTwitterPinterestSave分享0 Several recent science papers try to find evolution in bird brains, genes, and behaviors. Do they succeed?Sexual selection conundrums: Sexual selection seems to work except when it doesn’t. That’s the apparent observation from two articles, one on Science Daily that claims shorebirds choose looks over brains, and one on Live Science that shocks readers with the news that peahens don’t pay much attention to the elaborate tail feathers of peacocks. This seems to contradict a classic case of sexual selection. Sure enough, tiny video cameras on peahens followed their gaze and found that they tended to focus below the neck, a Purdue biologist found: “The males put on this huge display, and females seem to look at only a small portion of it.” What’s a male to do? Neither article mentioned whether sexual selection matters in species like crows that show virtually no sexual dimorphism.Chicks vs mice: A study in PNAS tried to find how much divergence and convergence there is in the expression of brain genes between chickens and mice. The authors claim that their study “potentially resolves the complex relationship between developmental homology and functional characteristics on the molecular level and settles long-standing evolutionary debates,” but the actual results were mixed. The authors found some surprising examples of convergent evolution (homoplasy) – surprising given “very different developmental trajectories” of birds and mammals. They admitted their limited data set could have led to different results. As a result, their conclusions were tentative, requiring further study:Our results suggest that the pallium has undergone major transcriptomic reorganization, with traces of both molecular homoplasy and homology …. These results do not imply that there is no homology among other pallial sectors, only that homology is not a dominant factor in their adult gene expression patterns. Homology might have a greater impact on pallial gene expression if we had studied a greater number of smaller regions or even individual cells…. Considering these results, subsequent investigations into the evolution of the neocortex should complement studies of homology based on cell lineage with multiple levels of information in various taxa toward a holistic understanding of how its molecular programs were repurposed, resulting in such cognitive convergence.Cockatoo puzzle solving: Speaking of bird brains, cockatoos can perform intelligence tests on spatial and navigational skills as well as toddlers, and sometimes better than great apes, according to new experiments reported on Science Daily.Darwin’s finches again: A new book is out about Darwin’s finches – not so much about the birds, but about David Lack, the “father of evolutionary ecology,” who spent a lot of time trying to defend Darwin’s views about them. Ben C. Sheldon liked Ted Anderson’s book in his review for Nature. Some readers might be surprised to find out that Lack did more work than Darwin:Charles Darwin had remarkably little to say about how the birds that bear his name — Darwin’s finches — came to have such a variety of beaks, despite their iconic status in evolutionary biology. It was left to an English schoolmaster on sabbatical in the late 1930s to carry out the first serious work on this question.Sheldon did not mention the subsequent work by Peter and Rosemary Grant who found that changes to the birds’ beaks oscillated according to the weather. Lack only spent 4 months on a field trip studying the birds, compared to the Grants’ three decades. It’s doubtful Lack’s work contributed much to scientific understanding of the Galapagos finches as much as the starting of a new movement: “The central message of Anderson’s book is that Lack should be understood as someone who bridged the gap between traditional natural history and the development of its modern academic descendant, evolutionary ecology.” In short: the book is short on science, and big on name-dropping of the evolution giants Lack interacted with. Whether “evolutionary ecology” is a productive use of biologists’ time is another subject.Homing pigeon navigation: A bird article with no need for evolutionary theory, but implications for design, concerned homing pigeons’ uncanny ability to find home. Science Daily reported that new experiments show the birds are not simple “flying robots,” but use cognitive ability when deciding what cues to follow. They build a spatial map of their surroundings and can choose to head toward a feeder or home, depending on how hungry they are:“As we expected, the satiated pigeons flew directly to the home loft,” explains Prof. Hans-Peter Lipp, neuroanatomist at UZH [University of Zurich] and [Nicole] Blaser’s supervisor for her doctoral thesis. “They already started on course for their loft and only deviated from that course for a short time to make topography-induced detours.” The hungry pigeons behaved quite differently, setting off on course for the food loft from the very beginning and flying directly to that target. They also flew around topographical obstacles and then immediately adjusted again to their original course. Based on this procedure, Blaser concludes that pigeons can determine their location and their direction of flight relative to the target and can choose between several targets. They thus have a type of cognitive navigational map in their heads and have cognitive capabilities. “Pigeons use their heads to fly,” jokes the young biologist.There was no mention of evolution in the article.Was there ever a more useless, time-wasting, distracting theory than Darwinian evolution? It made some people famous who were able to look like they were doing science. It created camaraderie between fellow Darwine drinkers. But did it ever produce understanding of the natural world? After reading these articles, you be the judge. We think an intelligent design perspective would have brought the coveted “insight” and “understanding” far earlier, without all the obstacles forcing observations to fit the hunches of a Bearded Buddha. If you really need convincing, watch the new Illustra film Flight: The Genius of Birds.
13 June 2007Investment in South Africa’s economy has risen steadily from 14.7% of gross domestic product (GDP) in the first quarter of 2002 to 19.2% of GDP in the last quarter of 2006, President Thabo Mbeki told Parliament on Tuesday.In the last quarter of 2006, he said, investment grew at an annualised rate of 16%, well ahead of the 10% target of the government’s Accelerated and Shared Growth Initiative for South Africa (Asgi-SA).Delivering the Presidency’s budget vote in Cape Town, Mbeki said South Africa’s economic growth was breaking records, citing “independently published research from … academic experts, ratings agencies that advise investors, and market research organisations.“Check with all these experts and you will discover that they know what most South Africans know, that by September this year, the South African economy will have been growing for eight solid years, longer than ever before in the recorded economic history of our country.”SA’s current rate of growth “has remained at a steady high level for longer than ever before in our history,” the President said, with average real income per person rising at around 4% per year since 2004 and more than 500 000 new jobs being created annually since September 2004.“These facts are not contested among experts in the field, except for those who say that we may be undercounting some of these key numbers because the sample frames we use have not kept up with a changing economic structure,” Mbeki noted.“There are also some who assert that many of the jobs created are in cyclical sectors like retail and construction, where job security is tenuous. Others point out that a considerable number of the new jobs created are in the informal sector.”This was true, Mbeki said, but did not detract from the fact that “we are now creating jobs more rapidly than ever before in our history” and that, “unlike most developing economies, most of our jobs are created in the formal sector.”Mbeki said the country should “celebrate the fact that the overwhelming majority of South Africans believe, from their lived experience, that tomorrow is likely to be better than today, and that their own hard work will help make it happen.”SouthAfrica.info reporter Want to use this article in your publication or on your website?See: Using SAinfo material
A Web Developer’s New Best Friend is the AI Wai… Tags:#data#politics#wikileaks Why Tech Companies Need Simpler Terms of Servic… Three years after WikiLeaks shook up the international community by leaking more than 250,000 diplomatic cables, the organization is at it again. Yesterday, it unveiled 1.7 million documents from the era of Henry Kissinger in the form of a searchable database called PlusD. It’s the biggest leak of previously classified information in human history.The leak will undoubtedly make for some intriguing historical analyses and anecdotes, some of which pertain to people and organizations that still wield power. But it doesn’t say much for the continued relevance of WikiLeaks.With its leader under house arrest, its biggest source about to stand trial on capital charges and a financial blockade hamstringing its ability to raise money, it’s a wonder WikiLeaks can manage to get anything accomplished. With that in mind, the Kissinger cable leak is an impressive feat.How Far WikiLeaks Hath FallenYet for the most part, the things we’ll learn from this new trove of documents are based in the past. Three years ago, WikiLeaks was releasing data that had an immediate impact on things going on around the world. Prior to that, it made headlines by releasing the now-infamous video of a U.S. helicopter killing civilians in Iraq.Today, they’re putting out might be a gold mine for historians and academics, but it probably won’t impact the future as much as past data dumps have.It’s a radical departure from the rhetoric and expectations of late 2010. It was then that, emboldened by the impact of Cablegate and the Iraq War Logs, WikiLeaks proudly announced that it was in possession of a Bank of America executive’s hard drive, the contents of which would be released to the public. The leak, Assange assured the world, had the potential to “take down a bank or two.”Whatever Happened To That Hard Drive?And yet it never materialized. At least a portion of that data was allegedly destroyed by a former WikiLeaks collaborator with whom Assange had a falling out. It’s not clear what, if any, data remains. The data, the seizure of which caused Bank of America to launch an internal, preemptive investigation, has yet to see the light of day.Since those triumphant, headline-grabbing days, WikiLeaks has been considerably quieter, periodically releasing data that might be interesting, but which lacks the impact of earlier dumps. Last year, the organization leaked millions of internal emails from private intelligence firm Statfor. It revealed a few intriguing details, but the emails were mostly, as GigaOm’s Matthew Ingram put it, “underwhelming.” As Ingram pointed out, WikiLeaks was no longer working with the influential media partners it boasted in 2010. Instead of teaming up with journalists from the New York Times, Guardian and Der Spiegel, Assange was relying on the likes of Anonymous, a shadowy collective with an altogether different type of reach than the Grey Lady. Losing Partners and Data SourcesEven more so than it needs powerful media partners, an organization like WikiLeaks needs reliable, well-placed sources. It’s worth recalling that Bradley Manning, the Army private accused of handing WikiLeaks the Collateral Murder video and diplomatic cables, is about to stand trial on charges that could result in his execution.There’s a certain deterrent factor at play there. And on a more practical level, WikiLeaks no longer has a source quite as well placed as Manning now that he’s in jail. Meanwhile, the hacker who leaked the StratFor emails could face life in prison. Governments have little tolerance for the type of ruckus WikiLeaks has caused, and they’re making that clear to would-be collaborators by aggressively prosecuting the sources of past leaks. Combine these factors with the financial blockade, Assange’s legal woes and infighting within the organization and it’s easy to conclude that WikiLeaks has been rather handily marginalized.Sure, there’s still global fallout from past leaks, and the Manning trial, a historical event with huge implications, hasn’t even started. But WikiLeaks is clearly less nimble and impactful than it was three years ago. And short of a bombshell such as a Manning acquittal or another explosive leak on the order of the promised BofA disclosure, there’s little reason to think things are going to turn around any time soon.

(AP Photo/Andy Brownbill)MELBOURNE, Australia — Novak Djokovic was so good, so relentless, so pretty much perfect, that Rafael Nadal never stood a chance.Djokovic reduced one of the greats of the game to merely another outclassed opponent — just a guy, really — and one so out of sorts that Nadal even whiffed on one of his famous forehands entirely.ADVERTISEMENT Right from the start, though, this shaped up nothing like their only previous Australian Open title match, back in 2012, which Djokovic won in 5 hours, 53 minutes, the longest Grand Slam final in history.Evenly matched as they were that night, this time was no contest. None whatsoever. It lasted a tad more than 2 hours.Watching things swing so immediately and irrevocably in Djokovic’s direction really was rather hard to comprehend, as was how someone of Nadal’s experience and excellence could come out of the gate quite so poorly.Nerves? Perhaps they played a role. So, of course, did Djokovic, whose defense was impenetrable.No ball, no matter how well-struck, seemed to be out of Djokovic’s reach. He slid and stretched and occasionally even did the splits, contorting his body to get wherever he needed to.Djokovic grabbed 13 of the first 14 points, including all four that lasted 10 strokes or more. A trend was established.Of most significance, Nadal was broken the very first time he served Sunday. That gave Djokovic one more break of Nadal than the zero that the Spaniard’s five preceding opponents had managed combined. But none of them is Djokovic, the best returner in the game now — and maybe ever.Not a shabby returner, either, Nadal could make no headway on this day. Djokovic won each of the initial 16 points he served and 25 of the first 26.By the end of the second set, after 75 minutes of action, Djokovic had won nearly twice as many points (59-30), made more winners (23-14) and far fewer unforced errors (20-4), while taking 14 of 17 points that lasted at least 10 strokes.The longest was a 22-shot point, which ended when Nadal netted a backhand to give Djokovic a set point at the end of the first. Djokovic raised his right fist and held it there while staring at his guest box. LATEST STORIES US judge bars Trump’s health insurance rule for immigrants In a remarkably dominant and mistake-free performance that yielded a remarkably lopsided result, the No. 1-ranked Djokovic overwhelmed Nadal 6-3, 6-2, 6-3 on Sunday night to win a record seventh Australian Open championship and a third consecutive Grand Slam title, raising his count to 15 overall.“An amazing level of tennis,” Nadal acknowledged.FEATURED STORIESSPORTSPrivate companies step in to help SEA Games hostingSPORTSUrgent reply from Philippine football chiefSPORTSWin or don’t eat: the Philippines’ poverty-driven, world-beating pool starsAfter dropping only four games in the semifinals, Djokovic spoke about being “in the zone.” Clearly, he did not budge from there, producing 34 winners and only nine unforced errors Sunday.And this was against no slouch, of course: Nadal is ranked No. 2, owns 17 major trophies himself and hadn’t dropped a set in the tournament. He was on the right path. Nadal could do nothing to stop him.Sports Related Videospowered by AdSparcRead Next Private companies step in to help SEA Games hosting SEA Games hosting troubles anger Duterte Oil plant explodes in Pampanga town “Sometimes, this tournament has been tough for me, in terms of injury,” said Nadal, who dropped to 1-4 in Australian Open finals, “and other times, in terms of opponents — like tonight.”A sore right elbow cost Djokovic the last half of 2017. It contributed to a fourth-round loss in Melbourne a year ago, right before he decided to have surgery.All that is in the past.The 31-year-old Serb is once again at an elite level. If anything, the gap between him and the rest is growing right now.“I’m just trying to contemplate on the journey in the last 12 months,” Djokovic said, mentioning what he called “quite a major injury.”“To be standing now here in front of you today and managing to win this title and three out of four Slams is truly amazing,” Djokovic said. “I am speechless.”Nadal also has dealt with all manner of health issues. He retired from his Australian Open quarterfinal and U.S. Open semifinal last year with right leg problems, had an offseason operation on his right ankle, and hadn’t competed in about four months when play began in Melbourne.“It was so important to be where I am today, coming back from injury, and it’s good inspiration for me for what’s coming,” Nadal said. “I’m going to keep fighting hard to be a better player.”Djokovic and Nadal know each other, their styles and their patterns all too well. This was their 53rd meeting — more than any other pair of men in the half-century professional era — and record-equaling 15th at a Grand Slam tournament. It was also their eighth matchup in a major final.So there should not have been any mysteries out there on Rod Laver Arena’s blue court as they began with the temperature, which had topped 105 degrees (40 Celsius) in recent days, at a manageable 75 (25 C) and just a hint of wind. Oil plant explodes in Pampanga town Grace Poe files bill to protect govt teachers from malicious accusations But Djokovic left Nadal smirking or gritting his teeth or punching his racket strings, unable to compete at all.“Tonight,” Nadal said, “was not my night.”So Djokovic added to previous triumphs in Melbourne in 2008, 2011, 2012, 2013, 2015 and 2016, along with four at Wimbledon, three at the U.S. Open and one at the French Open.He broke his tie with Roger Federer and Roy Emerson for most Australian Open men’s titles. He also broke a tie with Pete Sampras for third-most Grand Slam trophies; Djokovic only trails Federer, with 20, and Nadal.And he is gaining on them.ADVERTISEMENT ‘We are too hospitable,’ says Sotto amid SEA Games woes NLEX holds off much-improved Columbian for first win Don’t miss out on the latest news and information.

FPGA Transceivers Transceivers play a major role in optimizing FPGAs for challenging cost, power and performance requirements. Many applications need up to 24 high-speed full-duplex transceiver channels. They also need SerDes transceivers that can support baud rates from 250 Mbps to 12.7 Gbps to cover the full range of SDI, Ethernet up to 10Gbps, JESD204B converters and other applications. One primary advantage of optimizing transceivers for this range over downgrading a higher-speed SerDes adapted from a high-end FPGA is that it has significantly lower power at all baud rates compared to a downgraded SerDes approach.Numerous architectural decisions contribute to cutting FPGA transceiver power consumption, from implementing the transceiver using a half-rate architecture, to using a highly-shared architecture for the transmit PLLs. Ideally, the FPGAs should have 1–6 quad-channel transceivers, for a total of up to 24 SerDes channels. A number of equalization features allow longer distances and/or the use of low-cost materials in printed circuit boards and backplanes. Special phased-locked loop (PLL) features can deliver user benefits ranging from more flexible clock and baud rate selection, to simplified compliance with radiated-emission requirements, to higher bandwidth options.Debug and test is also important, including the availability of built-in pseudo-random binary sequence (PRBS) generators and checkers and IEEE 1149.6 “AC JTAG” support for non-DC-coupled signals. Including a built-in eye monitor with debug software support enables designers to debug SerDes without an oscilloscope. One can optimize the tuning of DFE and CTLE parameters in real time and dial in the ideal settings for the final product (see Figure 2).click for larger image Figure 2: SerDes Eye Monitor Smart Debug Software. (Source: Microsemi) Solving the Security Challenge There are numerous threats to the security of a design today. Everything from the user’s design IP to the manufacturing process can be compromised. Critical security techniques and features include hardware roots of trust, strong cryptography coupled with top-notch key management at every stage, and devices with built-in passive and active countermeasures to protect against tampering. Figure 3 shows best practices for secure FPGA provisioning with a unique serial number, keys, and X.509 public key certificate.click for larger image Figure 3: Device Certificate Chain of Trust. (Source: Microsemi) With these components in place, both design and data security can be addressed. Design security requires that FPGAs utilize the keys and certificate provisioned by its manufacturer, plus other techniques—ranging from patented differential power analysis (DPA) countermeasures to techniques for protecting against side-channel attacks —to protect the user’s IP. Another way to increase design security is by using physically unclonable function (PUF) technology to generate a hardware intrinsic key.Data security requires the use of a crypto-processor dedicated to the FPGA user whose core is NIST-certified to implement many of the most commonly used cryptographic algorithms such as AES, SHA 2, ECC, RSA and DH, and includes a cryptographic-grade TRNG. The performance of the user’s crypto-processor should be suitable for many applications, reducing the costs (area, power, and licensing-related) compared with adding an accelerator to the FPGA fabric.There is growing demand for cost-optimized mid-range FPGAs that deliver significantly lower power at densities up to 500K logic elements (LEs) for communications, defense, and industrial markets. A new development roadmap has emerged that combines new process technologies and fabric designs with important transceiver changes and security features, enabling FPGAs to address the cost, power, performance and security requirements of mainstream applications while delivering all the benefits of non-volatile technologies.Ted Marena is the director of FPGA/SOC marketing at Microsemi. He has over 20 years’ experience in FPGAs. Previously Marena has held roles in business development, product & strategic marketing. He was awarded Innovator of the Year in February 2014 when he worked for Lattice Semiconductor. Marena has defined, created and executed unique marketing platform solutions for vertical markets including consumer, wireless small cells, industrial, cameras, displays and automotive applications. Marena holds a Bachelor of Science in electrical engineering Magna Cum Laude from the University of Connecticut and a MBA from Bentley College’s Elkin B. McCallum Graduate School of Business. Share this:TwitterFacebookLinkedInMoreRedditTumblrPinterestWhatsAppSkypePocketTelegram Tags: Digital Multiple trends are sending FPGAs down two distinct development paths. On one path, FPGAs are being optimized primarily to accelerate data center workloads. The data center focus is the next holy grail that the larger vendors are laser-focused on. On another development path, there are the traditional FPGA markets of networking, cellular infrastructure, defense, commercial aviation, industry 4.0 and medical. In these markets many engineers feel they are being abandoned. Their development challenges are quite different than the data center focus that the large vendors are focusing on. Here, designers face an increasingly difficult balancing act as they try to achieve a combination of low power and cost without sacrificing performance and security. Navigating this balancing act requires looking at FPGAs in a new way, using new process technology choices, fabric designs, transceiver strategies and built-in security measures. This has led to a new class of mid-range FPGAs that deliver new capabilities for traditional FPGA developers to leverage.New Process Technology Choices One way to reduce power while optimizing the cost of mid-range FPGAs is through the use of new process technologies. For example, using Silicon-Oxide-Nitride-Silicon (SONOS) non-volatile (NV) technology on a 28nm technology node provides a lower power advantage as compared to both SRAM-based FPGAs at the same or even smaller nodes. Previous-generation non-volatile FPGAs using 65nm-and-older floating gate NV technology are more expensive than SONOS. Whereas floating gate technology requires 17.5 V to program using large charge pumps that consume a substantial die area, SONOS technology requires only 7.5 V for programming, so charge pumps can be smaller. This technology enables a smaller die size and contributes to a more cost-effective device.SONOS technology delivers these benefits by using a single poly transistor stack with a non-conductive Nitride dielectric layer (silicon-nitride, Si3N4) as the charge storage element (see Figure 1). Using this approach, only a very small amount of charge will be lost in proximity to any defect that may exist in the bottom oxide. Because the stored charge is non-mobile in the insulating Nitride layer, most of the stored charge remains where it is, intact. A thinner bottom oxide can be used compared to the floating gate technology, and it can be programmed with lower programming voltages (~7.5 V) and smaller charge pumps. Fewer transistors are required with SONOS than with an SRAM memory element.Figure 1: SONOS technology. (Source: Microsemi) SONOS technology improves reliability thanks to its use of a push-pull cell containing an N-channel and a P-channel NV device. The NV devices are not in the data-speed path and are only used to control a standard transistor used as the data-path switch. This provides a large functional advantage because any variation in the NV device threshold voltage (Vt) does not change the switch conductance. The way the devices interact acts as a built-in quasi redundancy, preventing performance degradation over the life of the product.Power consumption is also reduced. First, the SONOS NV FPGA configuration cell enables two different programmable “configuration” states that control the FPGA data signal path, switching it off and on in a way that optimizes the switch device to provide much lower leakage than a standard transistor. Second, SONOS technology can put a device into a state that turns the supply voltage off to the configuration memories in the FPGA logic block while saving the user’s state in low-power latches. This lowers standby power by approximately two-thirds.There are two other important SONOS benefits. The first is “instant on” capabilities: because the FPGA logic configuration cell retains its state after power-down, there is no need to reload the FPGA design code when power is returned, and no need for an external boot PROM. Second, unlike the configuration memory in SRAM-based FPGAs that can flip state due to neutron hits, a SONOS device’s FPGA logic configuration is SEU-immune. The SONOS NV charge is stored in the nitride dielectric, which is not susceptible to charge loss from neutron hits.New Fabric Designs Another way to improve mid-range FPGA performance is through changes to the programmable logic fabric. This enables devices to meet mainstream performance requirements while consuming one-tenth the static power of competing SRAM FPGAs, and half the total power.Power and performance trade-offs are involved. As an example, 6-input LUTs can provide some speed benefits, but 4-input LUTs are the better choice for a power- and cost-optimized FPGA in a modern process technology. Meanwhile, as process technology has progressed from 65nm to 28nm and beyond, the delay of wiring has come to dominate logic delay, due to poor scaling of metal wire and via resistance. Widening the wires adds to the die area and cost. So, with each succeeding generation of process technology, inter-cluster delay becomes a significant contributor to the critical path, and the speed advantage of 6-input LUTs diminishes. Ensuring rapid direct connections between nearby LUTs can reduce intra-cluster delay, especially in conjunction with advanced synthesis and placement algorithms. Certain logic functions (such as MUX trees) greatly benefit from the direct connections.For best results, an FPGA family’s power-performance tradeoffs should be carefully optimized for a core logic supply voltage that is somewhat less than the nominal voltage for the process on which it is manufactured. In the case of 28nm SONOS devices this means optimizing the family for a 1.0V core logic supply voltage, with the option to use the full 1.05 V supply when extra speed is required.The final piece of the FPGA fabric is the math block, which should support 18-bit multiply-accumulate operations. Power savings are realized through the provision of a pre-adder with a full 19-bit result and an input value cascade chain, and by ensuring that the math block supports reduced precision 9-bit operations, including 9 × 9 dot-product mode. The latter is ideal for use in image processing and convolutional neural networks (CNNs). Leave a Reply Cancel reply You must Register or Login to post a comment.
