Registers of the Itanium CPU Architecture

In this second installment of the CPU register series, I take a look at the Itanium CPUs. Intel and HP designed Itanium throughout the 1990s. Intel hoped that it would be the successor to the old x86 architecture, with a bonus of not being legally obliged to share these secrets with anyone else (AMD specifically). When it went on the market in 2001, its performance was not competitive with x86, and was super expensive. While Itanium had x86 emulation, it was not fast enough to be useful. At the time, AMD was busy at work expanding x86 to 64-bit, which proved to be the winning strategy.

Registers of the x86 CPU architecture

I've never really looked closely at the individual registers upon which most of my computing is done. I stay comfortably above that stuff. But I've been curious of late, so I looked, and I got lost, but I don't regret it.

Programmer Day

Tomorrow will be a very special day. Not necessarily important or memorable, but special.
