This year I presented "Extended System Coherency for Mobile and Beyond" on the fundamentals of cache coherency. This blog is the first in a series and starts with cache coherency fundamentals.

Size mattersHow much does it take to increment a number? One instruction? Two? It is not as simple a question as you might imagine. And, believe me, this is one case where size matters.On an ARM processor…

This blog was initially posted on 27th April 2011 on blogs.arm.comAs we come to the end of our second engineering cycle, I thought it would be interesting to highlight 4 of the initiatives happening in…

I’ve just spent an amazingly busy and productive time at Cartes Paris,  the biggest and the most comprehensive global annual event dedicated to Secure Solutions for Payment, Identification and Mobility…

Originally this blog post was intended to be all-in-one, but I was suggested to split it into smaller parts.So what I'll do, is that I'll mention the features I'd like in my ARM processor, one at a time…

The ARM Cortex-A mobile application processor product line spans several generations and three main product tiers. Developers and SoC designers experienced with one or more of the newer ARM ARM Processors…
