Research Bits: Sept. 20
By Jesse Allen - 20 Sep, 2022 - Comments: 0

Multi-mode memristors Researchers from ETH Zurich, the University of Zurich, and Empa built a new memristor that can operate in multiple modes and could potentially be used to mimic neurons in more applications. “There are different operation modes for memristors, and it is advantageous to be able to use all these modes depending on an artificial neural network’s architecture,” said R... » read more

Security Research: Technical Paper Round-Up
By Linda Christensen - 16 Aug, 2022 - Comments: 0

A number of hardware security-related technical papers were presented at recent conferences, including the August 2022 USENIX Security Symposium and IEEE’s International Symposium on Hardware Oriented Security and Trust (HOST). Topics include side-channel attacks and defenses (including on-chip mesh interconnect attacks), heterogeneous attacks on cache hierarchies, rowhammer attacks and mitig... » read more

Processor power prediction Researchers from Duke University, Arm Research, and Texas A&M University developed an AI method for predicting the power consumption of a processor, returning results more than a trillion times per second while consuming very little power itself. “This is an intensively studied problem that has traditionally relied on extra circuitry to address,” said Zhiy... » read more

Technical Paper Round-Up: March 15
By Linda Christensen - 15 Mar, 2022 - Comments: 0

Research is expanding across a variety of semiconductor-related topics, from security to flexible substrates and chiplets. Unlike in the past, when work was confined to some of the largest universities, that research work is now being spread across a much broader spectrum of schools on a global basic, including joint research involving schools whose names rarely appeared together. Among the ... » read more

Designing a 2048-Chiplet, 14336-Core Waferscale Processor
By Technical Paper Link - 14 Mar, 2022 - Comments: 0

Abstract "Waferscale processor systems can provide the large number of cores, and memory bandwidth required by today’s highly parallel workloads. One approach to building waferscale systems is to use a chiplet-based architecture where pre-tested chiplets are integrated on a passive silicon-interconnect wafer. This technology allows heterogeneous integration and can provide significant perfor... » read more

A number of hardware security-related technical papers were presented at the August 2021 USENIX Security Symposium. The organization provides open access research, and the presentation slides and papers are free to the public. Topics include side-channel attacks and defenses, embedded security, hardware security tokens, and more. Here are some highlights with associated links:   [tab... » read more

The Evolution Of High-Level Synthesis
By Brian Bailey - 27 Aug, 2020 - Comments: 3

High-level synthesis is getting yet another chance to shine, this time from new markets and new technology nodes. But it's still unclear how fully this technology will be used. Despite gains, it remains unlikely to replace the incumbent RTL design methodology for most of the chip, as originally expected. Seen as the foundational technology for the next generation of EDA companies around the ... » read more

Logic Chip, Heal Thyself
By Susan Rambo And Ed Sperling - 11 Feb, 2020 - Comments: 0

If a single fault can kill a logic chip, that doesn’t bode well for longevity of complex multi-chip systems. Obsolescence in chips is not just an industry ploy to sell more chips. It is a fact of physics that chips don’t last more than a few years, especially if overheated, and hit with higher voltage than it can stand. The testing industry does a great job finding defects during manufac... » read more

Power/Performance Bits: Jan. 21
By Jesse Allen - 21 Jan, 2020 - Comments: 0

Two-layer MRAM Scientists at Tokyo Institute of Technology propose a simpler MRAM construction that could perform faster with less power than conventional memories. The idea relies on unidirectional spin Hall magnetoresistance (USMR), a spin-related phenomenon that could be used to develop MRAM cells with an extremely simple structure. The spin Hall effect leads to the accumulation of elect... » read more
