Birth of a World Beater

If you followed the Consumer Electronics Show news at all last week, you heard a lot about ARM, ARM, ARM. Mindshare-wise, it would appear to have Intel on the defensive. (I wonder how Intel feels about selling off their StrongARM now?)

I plan to learn more about ARM's architecture and products. For today's history lesson, Birth of a world beater features one of the original ARM designers.

I'm curious to learn the technical merits of the ARM architecture. Is it inherently superior? Or is the main advantage the scads of software eco-system available, with low-power coming from standard implementation and process tricks?

Technical superiority and business success don't always go hand-in-hand, anyway. I've attend HOTChips before, and I was amused how all the microprocessor experts there bemoaned x86's incredible success, even though they knew it was inferior to [insert your favorite CPU here];. x86 was just good enough to survive, and had been in the right place at the right time. Is now the time for ARM?
