CPU Performance Bottlenecks Limit Parallel Processing Speedups


Multi-core processors theoretically can run many threads of code in parallel, but some categories of operation currently bog down attempts to raise overall performance by parallelizing computing. Is it time to have accelerators for running highly parallel code? Standard processors have many CPUs, so it follows that cache coherency and synchronization can involve thousands of cycles of low-le... » read more

Scaling, Packaging, And Partitioning


Prior to the finFET era, most chipmakers either focused on shrinking or packaging, but they rarely did both. Going forward, the two will be inseparable, and that will lead to big challenges with partitioning of data and processing. The key driver here, of course, is that device scaling no longer provides appreciable benefits in power, performance and cost. Nevertheless, scaling does provide ... » read more

Bottlenecks For Edge Processors


New processor architectures are being developed that can provide two to three orders of magnitude improvement in performance. The question now is whether the performance in systems will be anything close to the processor benchmarks. Most of these processors doing one thing very well. They handle specific data types and can accelerate the multiply-accumulate functions for algorithms by distri... » read more

Using More Verification Cores


Semiconductor Engineering sat down to talk about parallelization efforts within EDA with Andrea Casotto, chief scientist for Altair; Adam Sherer, product management group director in the System & Verification Group of Cadence; Harry Foster, chief scientist for Mentor, a Siemens Business; Vladislav Palfy, global manager for applications engineering at OneSpin; Vigyan Singhal, chief Oski for ... » read more

System Bits: July 3


VW emissions tests cheat code found A team of researchers from UC San Diego, Ruhr University along with an independent researcher has uncovered the mechanism that Volkswagen used to circumvent U.S. and European emission tests over a period of at least six years before the EPA put the company on notice in 2015 for violating the Clean Air Act. The researchers found the code that allowed onboa... » read more

Software Modeling Goes Mainstream


Software modeling is finally beginning to catch on across a wide swath of chipmakers as they look beyond device scaling to improve performance, lower power, and ratchet up security. Software modeling in the semiconductor industry historically has been associated with hardware-software co-design, which has grown in fits and starts since the late 1990s. The largest chipmakers and systems compa... » read more

Moving Electrons Is Getting Harder


Numerous executives across the ecosystem—from EDA and equipment companies to foundries—recently have stated that Moore's Law has at least 10 more years of life. This is interesting math, considering the semiconductor industry is now working on 10nm, with chips expected to roll out next year. So given that Moore's Law is on a two-year cadence of doubling the number of transistors every 24... » read more
