Week In Review: Design, Low Power


Tools & IP Codasip unveiled three commercially licensed add-ons to the Western Digital SweRV Core EH1, aiming to allow it to be designed into a wider range of applications. The SweRV Core EH1 is a 32-bit, dual-issue, RISC-V ISA core with a 9-stage pipeline, open-sourced through CHIPS Alliance. The add-ons offer a floating-point unit (FPU) that supports the RISC-V single precision [F] and d... » read more

Zeptosecond measurements A group of researchers have set a new world’s record for the shortest timespan measurement. DESY, Fritz-Haber-Institute and Goethe University Frankfurt have measured how long it takes for a photon to cross a hydrogen molecule. The result? About 247 zeptoseconds. A zeptosecond is a trillionth of a billionth of a second (10-21 seconds). This is said to be the sh... » read more

DNA storage for TV shows DNA storage was a hot topic about two or so years ago, but it’s been somewhat quiet since that time. DNA storage is back in the news. For the first time, Twist Bioscience has stored an episode of a new Netflix show using its synthetic DNA technology. The new show, BIOHACKERS, is a new six-part biotech thriller. Deoxyribonucleic acid (DNA) is a molecule that car... » read more

Open-Source Hardware Momentum Builds


Open-source hardware continues to gain ground, spearheaded by RISC-V — despite the fact that this processor technology is neither free nor simple to use. Nevertheless, the open-source hardware movement has established a solid foothold after multiple prior forays that yielded only limited success, even for processors. With demand for more customized hardware, and a growing field of startups... » read more

MRAM speed Researchers at ETH Zurich and Imec investigated exactly how quickly magnetoresistive RAM (MRAM) can store data. In the team's MRAM, electrons with opposite spin directions are spatially separated by the spin-orbit interaction, creating an effective magnetic field that can be used to invert the direction of magnetization of a tiny metal dot. "We know from earlier experiments, i... » read more

Plastic gold ETH Zurich has developed an 18-carat gold nugget based on plastic. Instead of traditional metallic alloy elements, ETH’s gold nugget consists of a matrix of plastic. Weighing five to ten times less than traditional gold, ETH’s plastic gold can be used in watches, jewelry, radiation shielding, catalysis and electronics. Gold is a chemical element used in a plethora of app... » read more

Open Source Hardware Risks


Open-source hardware is gaining attention on a variety of fronts, from chiplets and the underlying infrastructure to the ecosystems required to support open-source and hybrid open-source and proprietary designs. Open-source development is hardly a new topic. It has proven to be a successful strategy in the Linux world, but far less so on the hardware side. That is beginning to change, fueled... » read more

Understanding the Interactions of Workloads and DRAM Types: A Comprehensive Experimental Study


Abstract "It has become increasingly difficult to understand the complex interaction between modern applications and main memory, composed of DRAM chips. Manufacturers are now selling and proposing many different types of DRAM, with each DRAM type catering to different needs (e.g., high throughput, low power, high memory density). At the same time, the memory access patterns of prevalent and... » read more

Metalens breakthroughs Using a conventional lithography system, Harvard has developed what researchers call an all-glass, centimeter-scale metalens. A metalens is a flat surface, which makes use of nanostructures to focus light. It’s a disruptive technology that could displace traditional glass-based lenses. Applications include virtual reality (VR) devices, biological imaging techniques ... » read more

Flexible battery Researchers at ETH Zurich developed a flexible thin-film battery that can be bent, stretched, and twisted without interrupting the supply of power. Key to the battery is a new electrolyte and entirely flexible components. "To date, no one has employed exclusively flexible components as systematically as we have in creating a lithium-ion battery," said Markus Niederberger, P... » read more
