Power/Performance Bits: March 2


Fast-charging EV battery Electric vehicle adoption faces challenges from consumers' range anxiety and the extended lengths of time needed to charge a car's battery. Researchers at Pennsylvania State University are trying to address this by developing lithium iron phosphate EV batteries that have a range of 250 miles with the ability to charge in 10 minutes. It also is expected to have a lifeti... » read more

Power/Performance Bits: Feb. 23


Photonic AI accelerator There are now many processors and accelerators focused on speeding up neural network performance, but researchers at the University of Münster, University of Oxford, Swiss Federal Institute of Technology Lausanne (EPFL), IBM Research Europe, and University of Exeter say AI processing could happen even faster with the use of photonic tensor processors that can handle mu... » read more

FeFETs Bring Promise And Challenges


Ferroelectric FETs (FeFETs) and memory (FeRAM) are generating high levels of interest in the research community. Based on a physical mechanism that hasn’t yet been commercially exploited, they join the other interesting new physics ideas that are in various stages of commercialization. “FeRAM is very promising, but it's like all promising memory technologies — it takes a while to get b... » read more

Power/Performance Bits: Feb. 16


Superconducting microprocessor Researchers at Yokohama National University created a superconducting processor with zero electrical resistance. Huge amounts of power are being used by computers today, and compared to the human brain, they are many orders of magnitude less efficient. Superconductors have been a popular approach to making computers more efficient, but this requires extreme co... » read more

Design For Reliability


Circuit aging is emerging as a mandatory design concern across a swath of end markets, particularly in markets where advanced-node chips are expected to last for more than a few years. Some chipmakers view this as a competitive opportunity, but others are unsure we fully understand how those devices will age. Aging is the latest in a long list of issues being pushed further left in the desig... » read more

Design Support For A Green IoT


By Dirk Mayer and Roland Jancke The Internet of Things (IoT) is growing rapidly all around the world. New devices are continually being added, all collecting a variety of data and transmitting them (often wirelessly) to edge devices, which in turn relay the data to the cloud for further processing. It is estimated that in a few years IoT devices will be responsible for over 20% of global ene... » read more

The Many Flavors Of UPF: Which Is Right For Your Design?


Energy efficient electronic systems require sophisticated power management architectures that present difficult low-power verification challenges. Accellera introduced the Unified Power Format (UPF) standard in 2007 to help engineers deal with these complex issues. To keep pace with the growing complexity of low-power designs, the UPF standard has itself continued to evolve through the relea... » read more

Modeling PCBs For Common Causes Of Failure


By Theresa Duncan and Michael Blattau When designing printed circuit boards (PCBs), keep in mind the major causes of electronic failure: thermal cycling, vibration, and mechanical shock and drop. You can perform a variety of physical tests to determine how and why electronics fail, however, a much faster and cost-effective solution is PCB modeling and simulation. When simulation is used i... » read more

CXL: Sorting Out The Interconnect Soup


In the webinar Hidden Signals: Memory and Interconnect Decisions for AI, IoT and 5G, Shane Rau of IDC and Rambus Fellow Steven Woo discussed how interconnects were a critical enabling technology for future computing platforms. One of the major complications was the “interconnect soup” of numerous and divergent interface protocols. The Compute Express Link (CXL) standard offers to sort out m... » read more

Usage Models Driving Data Center Architecture Changes


Data center architectures are undergoing a significant change, fueled by more data and much greater usage from remote locations. Part of this shift involves the need to move some processing closer to the various memory hierarchies, from SRAM to DRAM to storage. There is more data to process, and it takes less energy and time to process that data in place. But workloads also are being distrib... » read more
