System Bits: July 3


CMU prof gets a shot at new supercomputer The National Energy Research Scientific Computing Center will greet its Perlmutter supercomputing system in early 2020. The Cray-designed machine will be capable of 100 million billion floating operations per second. Zachary Ulissi of Carnegie Mellon University will be among the first researchers to use the supercomputer. "When this machine comes on... » read more

Security’s Very Strange Path To Success


Security at the chip level appears to be heading toward a more promising future. The reason is simple—more people are willing to pay for security than in the past. For the most part, security is like insurance. You don't know it's working until something goes wrong, and you don't necessarily even know right away if there has been a breach. Sometimes it takes years to show up, because it ca... » read more

TOPS, Memory, Throughput And Inference Efficiency


Dozens of companies have or are developing IP and chips for Neural Network Inference. Almost every AI company gives TOPS but little other information. What is TOPS? It means Trillions or Tera Operations per Second. It is primarily a measure of the maximum achievable throughput but not a measure of actual throughput. Most operations are MACs (multiply/accumulates), so TOPS = (number of MAC... » read more

Automotive Trends Create New Challenges For Wiring Harness Development


The rapid introduction of new technologies and the influx of automotive start-ups into the market has led to a multitude of challenges for harness development. OEMs and startups alike must consider the number and sophistication of technology features they integrate into their vehicles as they have a direct effect on harness weight, bundle diameter, and cost. Electrification, autonomous drive an... » read more

Week in Review: IoT, Security, Auto


Products/Services Visa agreed to acquire the token and electronic ticketing business of Rambus for $75 million in cash. The business involved is part of the Smart Card Software subsidiary of Rambus. It includes the former Bell ID mobile-payment businesses and the Ecebs smart-ticketing systems for transit providers. Meanwhile, Rambus expanded its CryptoManager Root of Trust product line. “Sec... » read more

Rethinking What Goes On A Chip


There are hints across the chip industry that chipmakers are beginning to reexamine one of the basic concepts of chip design. For more than 50 years, progress in semiconductors was measured by the ability to double the density of transistors on a piece of silicon. While that approach continues to be useful, the power and performance benefits have been dwindling for the past couple of nodes. ... » read more

Providing An AI Accelerator Ecosystem


A key design area for AI systems is the creation of Machine Learning (ML) algorithms that can be accelerated in hardware to meet power and performance goals. Teams designing these algorithms find out quickly that a traditional RTL design flow will no longer work if they want to meet their delivery schedules. The algorithms are often subject to frequent changes, the performance requirements may ... » read more

Open Source Processors: Fact Or Fiction?


Open source processors are rapidly gaining mindshare, fueled in part by early successes of RISC-V, but that interest frequently is accompanied by misinformation based on wishful thinking and a lack of understanding about what exactly open source entails. Nearly every recent conference has some mention of RISC-V in particular, and open source processors in general, whether that includes keyno... » read more

Google Cloud—A View From The Top


I recently had the opportunity to attend a retreat-style event in Napa Valley hosted by the Google Cloud team. Like many such events I’ve attended over the years, the guests were treated to excellent accommodations, fabulous food, a good amount of free time for networking or to partake in activities, relevant and on-point presentations and world-class wine (this is Napa Valley after all). All... » read more

Test Chips Play Larger Role At Advanced Nodes


Test chips are becoming more widespread and more complex at advanced process nodes as design teams utilize early silicon to diagnose problems prior to production. But this approach also is spurring questions about whether this approach is viable at 7nm and 5nm, due to the rising cost of prototyping advanced technology, such as mask tooling and wafer costs. Semiconductor designers have long b... » read more
