Amazing work by such a tiny team! Btw the article has some great links to interactive digital design online simulator

A History of ARM (part 1): Building the first chip In 1983, Acorn Computers needed a CPU. So 10 people built one. arstechnica.com/gadgets/2022/0…



I am pleased to share a small but valuable Unity feature I have been working on recently. It enables customization of certain visuals for each renderer at no additional CPU performance cost. discussions.unity.com/t/renderer-sha…

I recently had the honor of interviewing Zen’s chief architect Mike Clark! I tried to fit in as many microarchitecture questions as I could, including x64 vs ARM ISA power efficiency, 4k vs larger page sizes, 64-byte cache lines, scatter/gather and more: computerenhance.com/p/an-interview…
