Power/Performance Bits: Aug. 24


Low power AI Engineers at the Swiss Center for Electronics and Microtechnology (CSEM) designed an SoC for edge AI applications that can run on solar power or a small battery. The SoC consists of an ASIC chip with RISC-V processor developed at CSEM along with two tightly coupled machine-learning accelerators: one for face detection, for example, and one for classification. The first is a bin... » read more

New Power, Performance Options At The Edge


Increasing compute intelligence at the edge is forcing chip architects to rethink how computing gets partitioned and prioritized, and what kinds of processing elements and memory configurations work best for a particular application. Sending raw data to the cloud for processing is both time- and resource-intensive, and it's often unnecessary because most of the data collected by a growing nu... » read more

One-On-One: Lip-Bu Tan


Lip-Bu Tan, CEO of Cadence, sat down with Semiconductor Engineering to talk about the impact of massive increases in data across a variety of industries, the growing need for computational software, and the potential implications of U.S.-China relations. What follows are excerpts of that discussion. SE: What do you see as the biggest change for the chip industry? Tan: We're in our fifth g... » read more

Power/Performance Bits: May 25


5G energy harvesting Researchers at Georgia Institute of Technology propose a way to harvest power for IoT devices using 5G networks. The team's device uses a flexible Rotman lens-based rectifying antenna (rectenna) system capable of millimeter-wave harvesting in the 28-GHz band. “With this innovation, we can have a large antenna, which works at higher frequencies and can receive power fr... » read more

Manufacturing Bits: March 23


Measuring acceleration The National Institute of Standards and Technology (NIST) has developed a new and better way to measure acceleration. NIST has developed an optomechanical accelerometer, a technology that has more resolution and bandwidth than conventional accelerometers. Optomechanical accelerometers uses laser light of a known frequency to measure acceleration. With the technology, ... » read more

Power/Performance Bits: Feb. 8


Transparent sensor Researchers at Osaka University created a thin, flexible, transparent sensor using silver nanowire networks. High-resolution printing was used to fabricate the centimeter-scale cross-aligned silver nanowire arrays, with reproducible feature sizes from 20 to 250 micrometers. As a proof-of-concept for functionality, they used their arrays to detect electrophysiological signals... » 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

Power/Performance Bits: Dec. 29


Safer Li-ion batteries Scientists from Stanford University and the Department of Energy's SLAC National Accelerator Laboratory propose a way to make lithium-ion batteries lighter, more efficient, and fire resistant. One of the heaviest components of lithium-ion batteries are the copper or aluminum sheets that act as current collectors. "The current collector has always been considered de... » read more

Power/Performance Bits: Aug. 25


AI architecture optimization Researchers at Rice University, Stanford University, University of California Santa Barbara, and Texas A&M University proposed two complementary methods for optimizing data-centric processing. The first, called TIMELY, is an architecture developed for “processing-in-memory” (PIM). A promising PIM platform is resistive random access memory, or ReRAM. Whil... » read more

DAC 2020 Day One


DAC 2020 is like no other Design Automation Conference. It is virtual for this year — and hopefully only this year. The COVID pandemic has proven that face-to-face meetings and conferences are invaluable for many reasons. But with none of the distractions of a traditional conference, focusing on the content was easy. And because the sessions have been pre-recorded, the speakers for each se... » read more
