It was a hacker news post actually: the presenter's delivery is a bit dry... but his project is impressive:
https://media.ccc.de/v/34c3-9058-everything_you_want_to_know_about_x86_microcode_but_might_have_been_afraid_to_ask#t=2467 https://media.ccc.de/v/34c3-9058-everything_you_want_to_know...
The SEM shots of the internal RAM/ROM starts around 24:00, I thought it was pretty cool.
The whole purpose of what they are doing is to try and reverse engineer the microcode to write their own.
- bayindirh 9y agoThanks, I'll take a look tomorrow. For more uCode work, there's http://inertiawar.com/microcode/ http://inertiawar.com/microcode/ which contains some interesting bits.
- tomxor 9y agoThanks, I do find microarchitecture stuff really interesting but it's a bit out of my depth if i'm honest.
- bayindirh 9y agoI find CPUs fascinating to be honest. While they are complex, they are not impenetrable. Playing with small assembly snippets and simulators helped me a lot to understand them. Also, other architectures such as MIPS and M68K have simpler to understand ISAs which accelerate the process of understanding these small wonders.
