Who Will Regulate Data Exchanges In Chiplets?


Scaling is still important when it comes to logic and low power, but it's no longer the main avenue for improving performance. What used to be a single chip, comprised of various IP blocks and components on a single SoC, is giving way to a heterogeneous collection of chiplets — at least for the big chipmakers and system companies at the leading edge. Chiplets are currently the best solutio... » read more

Week In Review: Auto, Security, Pervasive Computing


Intel issued an advisory of a potential security vulnerability in some of its processors. The company recommends updating to the latest firmware version. NVIDIA unveiled its GH200 Grace Hopper platform, based on 144 Arm Neoverse cores and 282GB of HBM3e memory. Meanwhile, Chinese internet companies including Baidu, ByteDance, Tencent, and Alibaba ordered about $5 billion worth of A800 proces... » read more

Week In Review: Design, Low Power


U.S. President Joe Biden issued an executive order to restrict U.S. investment in Chinese companies, targeting semiconductors and microelectronics, quantum information technologies, and artificial intelligence systems with military or intelligence applications. Specific technologies within these groups will be defined later. Some will only require investors to notify the Department of the Tre... » read more

Modeling Optical Loss And Crosstalk Noise For Silicon-Photonic-Based Neural Networks Of Different Scales 


A technical paper titled “Analysis of Optical Loss and Crosstalk Noise in MZI-based Coherent Photonic Neural Networks" was published by researchers at Colorado State University (Fort Collins), NVIDIA, and Arizona State University. Abstract: "With the continuous increase in the size and complexity of machine learning models, the need for specialized hardware to efficiently run such model... » read more

Using Generative AI To Connect Lab To Fab Test


Executive Insight: Thomas Benjamin, CTO at National Instruments, sat down with Semiconductor Engineering to discuss a new way of looking at test, using data as a starting point and generative AI as a bridge between different capabilities. SE: What are the big changes you're seeing and how is that affecting movement of critical data from the lab to the fab? Benjamin: If you walk into any m... » read more

AI Transformer Models Enable Machine Vision Object Detection


The object detection required for machine vision applications such as autonomous driving, smart manufacturing, and surveillance applications depends on AI modeling. The goal now is to improve the models and simplify their development. Over the years, many AI models have been introduced, including YOLO, Faster R-CNN, Mask R-CNN, RetinaNet, and others, to detect images or video signals, interp... » read more

Improving Performance And Lowering Power In Automotive


Automotive OEMs are boosting their investments across the semiconductor ecosystem as stepping stones toward electrification and autonomy, and they are starting to encounter some of the same issues chipmakers have been wrestling with at advanced nodes — massive compute performance, thermal and power issues, reliability over extended lifetimes, and a highly diverse and geographically distribute... » read more

Blog Review: July 19


Siemens' Keith Felton argues that co-design-driven semiconductor package planning and prototyping is critical for design success and points to how interchange formats enable designers to make trade-off decisions for both the package and the board and communicate those recommendations back to the other design team in formats that are native to their tools. Cadence's Xin Mu explains precoding ... » read more
