New Memory Architecture For Local Differential Privacy in Hardware


A technical paper titled "Two Birds with One Stone: Differential Privacy by Low-power SRAM Memory" was published by researchers at North Carolina State University, University of South Alabama, and University of Tennessee. Abstract "The software-based implementation of differential privacy mechanisms has been shown to be neither friendly for lightweight devices nor secure against side-channe... » read more

Challenges In RISC-V Verification


Designing a single-core RISC-V processor is relatively easy, but verifying it and debugging it is a different story. And it all becomes more complicated when multiple cores are involved, and when those cores need to be cache-coherent. Ashish Darbari, CEO of Axiomise, talks with Semiconductor Engineering about using assertions and formal verification technology to find bugs and prove coherency i... » read more

Research Bits: Apr. 2


Stretchy, sensitive circuits Researchers from Stanford University developed skin-like, stretchable integrated circuits capable of driving a micro-LED screen with a refresh rate of 60 Hz and detecting a braille array that is more sensitive than human fingertips. The stretchable transistors are made from semiconducting carbon nanotubes sandwiched between soft elastic electronic materials. The... » read more

Cache Coherency In Heterogeneous Systems


Until recently, coherency was something normally associated with DRAM. But as chip designs become increasingly heterogeneous, incorporating more and different types of compute elements, it becomes harder to maintain coherency in that data without taking a significant hit on performance and power. The basic problem is that not all compute elements fetch and share data at the same speed, and syst... » read more

The Challenges Of Working With Photonics


Experts at the Table: Semiconductor Engineering sat down to talk about where photonics is most useful — and most vulnerable — with James Pond, fellow at Ansys; Gilles Lamant, distinguished engineer at Cadence; and Mitch Heins, business development manager for photonic solutions at Synopsys. What follows are excerpts of that conversation. To view part one of this discussion, click here. ... » read more

Chip Industry Week In Review


By Adam Kovac, Karen Heyman, and Liz Allan.  China introduced strict procurement guidelines aimed at blocking the use of AMD and Intel processors in government computers. Meanwhile, China urged the Netherlands to ease restrictions on deep ultraviolet (DUV) litho equipment, according to Nikkei Asia. DUV is an older technology, based on 193nm ArF lasers, but in conjunction with multi-p... » read more

Optimizing Event-Based Neural Network Processing For A Neuromorphic Architecture


A new technical paper titled "Optimizing event-based neural networks on digital neuromorphic architecture: a comprehensive design space exploration" was published by imec, TU Delft and University of Twente. Abstract "Neuromorphic processors promise low-latency and energy-efficient processing by adopting novel brain-inspired design methodologies. Yet, current neuromorphic solutions still str... » read more

Career Transitions


Many people change their career path, sometimes to take on new challenges, sometimes following opportunity or money. As we learn, we develop both expertise and skill sets and in many cases expertise in one area has diminished value in another, meaning that it becomes more difficult to switch as we get older. But there are times when both knowledge and skills can be fully transferred, making the... » read more
