Wow... that's quite an achievement, I don't think I would even know where to start with building a CPU from scratch!

- bockris 17y agoWhile I don't have the skill/time to take on a project like this I really loved the book 'Code' by Charles Petzold. It walks you through the design of a CPU starting from nothing. There is also 'From NAND to Tetris in 12 steps', I haven't looked closely at that but from what I've heard it gives a similar level of detail.
- likpok 17y agoIt's somewhat simple. You just design the finite-state table and either use a ROM (microcode) or some sort of hardwired logic to implement it. I'm glossing over a lot of stuff here, but a simple CPU is just that, simple.
