Research Bits: March 22


Securing wireless communications without encryption Researchers from Princeton University, University of Michigan–Shanghai Jiao Tong University Joint Institute, and Xi’an Jiaotong University developed a millimeter-wave wireless chip that allows secure wireless transmissions and makes it challenging to eavesdrop on high-frequency wireless transmissions, even with multiple colluding bad acto... » read more

Always-On Sub-Microwatt Spiking Neural Network Based on Spike-Driven Clock- and Power-Gating for an Ultra-Low-Power Intelligent Device


Abstract: "This paper presents a novel spiking neural network (SNN) classifier architecture for enabling always-on artificial intelligent (AI) functions, such as keyword spotting (KWS) and visual wake-up, in ultra-low-power internet-of-things (IoT) devices. Such always-on hardware tends to dominate the power efficiency of an IoT device and therefore it is paramount to minimize its power diss... » read more

High-Level Synthesis For RISC-V


High-quality RISC-V implementations are becoming more numerous, but it is the extensibility of the architecture that is driving a lot of design activity. The challenge is designing and implementing custom processors without having to re-implement them every time at the register transfer level (RTL). There are two types of high-level synthesis (HLS) that need to be considered. The first is ge... » read more

Power/Performance Bits: Aug. 31


Securing memory Researchers at Columbia University suggest several ways to make computing more secure without imposing a system performance penalty. The efforts focus on memory security, specifically pointers. "Memory safety has been a problem for nearly 40 years and numerous solutions have been proposed. We believe that memory safety continues to be a problem because it does not distribute... » read more

Power/Performance Bits: June 7


Commercializing photonic MEMS Researchers from the University of California Berkeley, Daegu Gyeongbuk Institute of Science & Technology, SUSS MicroOptics, TSI Semiconductors, Gwangju Institute of Science and Technology, KAIST, Ecole Polytechnique Fédérale de Lausanne (EPFL), and Korea Polytechnic University demonstrated a path for commercial fabrication of photonic MEMS. Photonic MEMS... » read more

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. 25


Thinner, flexible touchscreens Researchers from RMIT University, University of New South Wales, and Monash University developed a thin, flexible electronic material for touchscreens. The material is 100 times thinner than current touchscreen materials. The new screens are still based on indium-tin oxide (ITO), a common touchscreen material. However, a liquid metal printing approach was used... » read more

Power/Performance Bits: Sept. 3


Nylon capacitor Researchers at the Max Planck Institute for Polymer Research, Johannes Gutenberg University of Mainz, and Lodz University of Technology developed a way to fabricate ferroelectric nylon thin-film capacitors. Nylons consist of a long chain of polymers and, along with use in textiles, exhibit ferroelectric properties. However, electronic applications have been limited as there ... » read more

Week in Review: IoT, Security, Autos


Products/Services Arm released a survey of 650 industry representatives about eSIM and iSIM technology. Ninety percent of the respondents were aware of eSIM, while 43% were unaware of iSIM. Vincent Korstanje, vice president and general manager, Emerging Businesses at Arm, cites the leading three obstacles to large commercial deployments: Resistance from traditional stakeholders (69% of respond... » read more

System Bits: July 23


Superconductivity seen in trilayer graphene Stanford University and University of California at Berkeley researchers discovered signs of superconductivity in stacking three-layer sheets of graphene, they report. “It’s definitely an exciting development,” says Cory Dean, a physicist at Columbia University. Dean notes that bilayer graphene superconducts only when the atomic lattices of ... » read more
