More Investments Into RISC-V – Qualcomm Backs SiFive, OpenHW Group Created

Some may doubt RISC-V will ever challenge Arm at least in some markets, but the industry is investing in solutions based on the royalty-free open source ISA, with this week SiFive securing $65.4 Million from various investors including Qualcomm Ventures LLC, and the announcement of the launch of the OpenHW Group, a new not-for-profit global organization aims to boost the adoption of open-source processors currently backed by 13 companies, and aiming to reach 25 sponsors by year’s end.

Wait, What? MIPS Becomes RISC-V
Classic CPU Company Exits Bankruptcy, Throws in the Towel

What a long, strange trip it’s been. MIPS Technologies no longer designs MIPS processors. Instead, it’s joined the RISC-V camp, abandoning its eponymous architecture for one that has strong historical and technical ties. The move apparently heralds the end of the road for MIPS as a CPU family, and a further (slight) diminution in the variety of processors available. It’s the final arc of an architecture.

Armv9: ARM Announces New Chip Architecture

Today, Arm introduced the Arm®v9 architecture in response to the global demand for ubiquitous specialized processing with increasingly capable security and artificial intelligence (AI). Armv9 is Arm's first new architecture in a decade, building on the success of Armv8, which today drives the best performance per watt

TSMC could jack chip prices up by 25% by the end of 2021

We could be paying even more for our CPUs, GPUs, and every other chip made by Taiwan Semiconductor Manufacturing Company (TSMC) if rumors of water price increases are correct.

Intel CPUs Face Spectre-Like Attack That Leaks Data | Darkreading

Researchers at the University of California San Diego (UCSD) have found a new way to execute Spectre-like side channel attacks against high-end Intel CPUs, including the recent Raptor Lake and Alder Lake microprocessors.

Like Spectre, the new technique, which the researchers have dubbed "Indirector," exploits a speculative execution feature in the Intel CPUs to redirect the control flow of a program — that is, the order in which it executes individual instructions and function calls.

Spectre-Like Side Channel Attack
An attacker could use the tactic to essentially trick the CPU into making incorrect speculative executions and leak sensitive data.
