Low-Latency Interconnect for Close-Coupled On-Chip Communication With Error Correction Code Protection (ETH Zurich)


A new technical paper titled "relOBI: A Reliable Low-latency Interconnect for Tightly-Coupled On-chip Communication" was published by researchers at ETH Zurich. Excerpt "On-chip communication is a critical element of modern systems-on-chip (SoCs), allowing processor cores to interact with memory and peripherals. Interconnects require special care in radiation-heavy environments, as any soft... » read more

What’s Different About HBM4


Memory bandwidth is limiting the flow of huge datasets that are needed to train AI models. There is much more data to process, store, and retrieve, but the speed at which that data moves through high-bandwidth memory (HBM) stacks is significantly lower than the speed at which data can be processed. Frank Ferro, group director for product management at Cadence, talks about the new HBM4 standard,... » read more

Physical AI Chip Sales Won’t Rival GenAI Anytime Soon


Fig. 1: When can we send our humanoid to pick up some milk at the store? Source: ChatGPT image There has been a lot of talk about physical AI, much of it very optimistic. Physical AI is happening, but more slowly than many expect. It will not rival GenAI soon. We’ll analyze humanoids, fully autonomous vehicles, then all application-specific robots (ASRs), ending with a rough estimate ... » read more

Research Bits: August 11


Fluorine-free ferroelectrics Researchers from Case Western Reserve University, Vanderbilt University, Pennsylvania State University, Brookhaven National Laboratory, Tennessee State University, and University of Tennessee created a ferroelectric polymer for infrared detectors and sensors in wearable electronics that is made without fluorine. The most common ferroelectric polymer is poly(vinylid... » read more

Accelerating The ASIL Journey For Chipmakers


In the world of automotive innovation, safety is the silent partner riding shotgun. As vehicles evolve into complex, software-defined machines, the stakes for ensuring functional safety have never been higher. This is where ISO 26262 steps in—not as a mere checklist, but as a comprehensive framework that guides engineers through the intricacies of designing systems that won’t just perform, ... » read more

Scalable I/O Virtualization: A Deep Dive Into PCIe’s Next Gen Virtualization


The demands of modern cloud computing—massive scale, constant agility, and tight security—are pushing traditional I/O virtualization to its limits. While SR-IOV (Single Root I/O Virtualization) was a foundational technology, it wasn't built for the high-density, multi-tenant environments common today. To meet this challenge, the PCIe specification has evolved with Scalable I/O Virtualiza... » read more

Security Verification In Semiconductor Development


By Shylaja Sen and Mouadh Ayache As advanced chips become increasingly embedded in our daily lives, developers must remain vigilant about potential security vulnerabilities. On top of PPA (power, performance and area), the focus in semiconductor development has been on minimizing faults to reduce the possibility of failure in mission mode. No one wants an alpha particle to cause their autono... » read more

AI Drives More Realistic Gaming


Video games are utilizing artificial intelligence to create increasingly realistic scenarios and interactions, enabled by big increases in processing horsepower and memory, and significantly faster data movement. GPUs, once confined to graphics rendering, are now also being deployed across a wide range of AI tasks, generating more realistic non-player characters, dynamic worlds, personalized... » read more
