Week In Review: Auto, Security, Pervasive Computing


Aerospace The NASA's Mars Perseverance Rover, which landed safely on Mars this week, has some new autonomous systems. The landing craft flew autonomously to find a good landing spot. When on the ground, the rover can drive in an autonomous traverse mode. Also autonomous is the small helicopter, the Ingenuity Mars Helicopter, being tested on Mars. The helicopter can fly up to 90 seconds autonom... » read more

The Problem With Benchmarks


Benchmarks long have been used to compare products, but what makes a good benchmark and who should be trusted with their creation? The answer to those questions is more difficult than it may appear on the surface, and some benchmarks are being used in surprising ways. Everyone loves a simple, clear benchmark, but that is only possible when the selection criteria are equally simple. Unfortuna... » read more

Longer Chip Lifecycles Increase Security Threat


The longer chips and electronic systems remain in use, the more they will need to be refreshed with software and firmware updates. That creates a whole new level of security risks, ranging from over-the-air intercepts to compromised supply chains. These problems have been escalating as more devices are connected to the Internet and to each other, but it's particularly worrisome when it invol... » read more

Edge-Inference Architectures Proliferate


First part of two parts. The second part will dive into basic architectural characteristics. The last year has seen a vast array of announcements of new machine-learning (ML) architectures for edge inference. Unburdened by the need to support training, but tasked with low latency, the devices exhibit extremely varied approaches to ML inference. “Architecture is changing both in the comp... » read more

Week In Review: Auto, Security, Pervasive Computing


Automotive/Mobility Chip makers in Taiwan will “do their best” to “squeeze out more chips” said Taiwan’s Minister of Economic Affairs Wang Mei-hua after having lunch with representatives of TSMC, UMC, Vanguard International Semiconductor Corp, and Powerchip Semiconductor Manufacturing Co., according to the Taipei Times. After the auto industry initially cut automotive chip orders bec... » read more

Von Neumann Is Struggling


In an era dominated by machine learning, the von Neumann architecture is struggling to stay relevant. The world has changed from being control-centric to one that is data-centric, pushing processor architectures to evolve. Venture money is flooding into domain-specific architectures (DSA), but traditional processors also are evolving. For many markets, they continue to provide an effective s... » read more

Power Models For Machine Learning


AI and machine learning are being designed into just about everything, but the chip industry lacks sufficient tools to gauge how much power and energy an algorithm is using when it runs on a particular hardware platform. The missing information is a serious limiter for energy-sensitive devices. As the old maxim goes, you can't optimize what you can't measure. Today, the focus is on functiona... » read more

Week In Review: Auto, Security, Pervasive Computing


Automotive Self-driving car company Cruise now has driverless cars on the streets of San Francisco, Calif., reports the San Francisco Chronicle. Cruise, which is backed by General Motors, is testing five driverless cars in the urban — and very hilly — environment of San Francisco. Cruise is using an EV — the Chevy Bolt — as a test vehicle. At Level 4 driving, the cars will not have a w... » read more

Re-Architecting SerDes


Serializer/Deserializer (SerDes) circuits have been helping semiconductors move data around for years, but new process technologies are forcing it to adapt and change in unexpected ways. Traditionally implemented as an analog circuit, SerDes technology has been difficult to scale, while low voltages, variation, and noise are making it more difficult to yield sufficiently. So to remain releva... » read more

Week In Review: Auto, Security, Pervasive Computing


Automotive Synopsys added support for Infineon's automotive AI chip, the AURIX TC4xx 32-bit microcontroller with parallel processing unit. Dialog Semiconductor announced automotive qualification for its DA7280 high-definition haptic driver. The company Alps Alpine is using the DA7280 in Alps Alpine Heavy, the latest version of its HAPTIC Reactor Linear Resonant Actuators (LRAs). Bosch, M... » read more
