Week In Review: Design, Low Power


IP, design Arm unveiled a number of new CPUs and GPUs. Based on the Armv9 architecture, the Cortex-X3 aims to improve single-threaded performance and targets a range of benchmarks and applications. The Cortex-A715 focuses on efficient performance, delivering a 20% energy efficiency gain and 5% performance uplift compared to Cortex-A710. In addition, the Cortex-A510 and DSU-110 were updated to ... » read more

Week In Review: Auto, Security, Pervasive Computing


Automotive, mobility The Lancet’s Road Safety 2022 report estimates that 1.35 million people die every year from road traffic injuries, with more than 50 million injured or disabled. Low-income and middle-income countries (LMICs) have the most deaths, accounting for 93% of the world's fatalities on roads. The four main risk factors for road injuries are speeding, impaired driving (drunk driv... » read more

Risks Rise As Robotic Surgery Goes Mainstream


As robotic-assisted surgery moves into the mainstream, so do concerns about security breaches, latency, and system performance. In the operating room, every second is critical, and technology failures or delays can be life-threatening. Robotic-assisted surgery (RAS) has around for a couple decades, but it is becoming more prevalent and significantly more complex. The technology often include... » read more

Blog Review: June 29


Synopsys' Emilie Viasnoff argues that optical sensors are critical building blocks of autonomous vehicles and that sensor digital twins have the potential to dramatically reduce the amount of field testing needed by using driving simulators for tasks ranging from design and testing to integration and autonomous driving system co-optimization. Siemens' Sumit Vishwakarma considers the evolutio... » read more

EDA Gaps At The Leading Edge


Semiconductor Engineering sat down to discuss what's changing on the leading edge of design, and what's needed to support those changes, with Bari Biswas, senior vice president for the Silicon Realization Group at Synopsys; Michael Jackson, corporate vice president for R&D at Cadence; Prashant Varshney, head of product for Microsoft Azure; Rob Aitken (Arm fellow at the time of this panel, n... » read more

Who Does Processor Validation?


Defining what a processor is, and what it is supposed to do, is not always as easy as it sounds. In fact, companies are struggling with the implications of hundreds of heterogenous processing elements crammed into a single chip or package. Companies have extensive verification methodologies, but not for validation. Verification is a process of ensuring that an implementation matches a specif... » read more

Why Hardware-Dependent Software Is So Critical


Hardware and software are two sides of the same coin, but they often live in different worlds. In the past, hardware and software rarely were designed together, and many companies and products failed because the total solution was unable to deliver. The big question is whether the industry has learned anything since then. At the very least, there is widespread recognition that hardware-depen... » read more

Blog Review: June 22


Arm's Andrew Pickard checks out a project at Sorbonne Université in Paris that is using the Cortex-M3 processor source code to model what is happening in the hardware at the microarchitectural level and find ways to prevent side-channel leakage of sensitive cryptographic information. Cadence's Paul McLellan digs into the development of high-NA EUV lithography and some of the challenges ahea... » read more

Week In Review: Auto, Security, Pervasive Computing


Automotive, mobility U.S. National Highway Traffic Safety Administration (NHTSA) release its first crash reports from ADAS (advanced driver assistance systems, i.e., SAE Level 2) and ADS (automated driving systems, i.e., SAE Levels 3-5).  The systems had to be in use at least 30 seconds before the crash in order for it to be reportable. The car may have had the system turned off at the time ... » read more

Blog Review: June 15


Ansys' Vidyu Challa considers common primary, or single-use, battery chemistries and how they affect that many important cell properties, such as energy density, flammability and safety, available cell constructions, temperature range, and shelf life. Synopsys' Rimpy Chugh and Rohit Kumar Ohlayan discuss some of the challenges arising from static linting of code, shifting linting left in the... » read more
