#2I always wanted to understand how a CPU works, how it transitions from one instruction to the next and makes a computer work. So I thought: let's implement one and run a C program on it.

#3The article looks really interesting, can't wait to dig in!
Side note: the articles on compilation also seem to be good and simple to understand, especially the one about code generation (which is a topic that other articles somehow always skip)

#4This is a really fantastic read! I wonder if the author might consider including links to the git source for the entire project?

#5Nice that you support multi-cycle memory instead of essentially using a big register file like https://nandgame.com/ uses.
I recently came across https://makerchip.com/, and the TL-Verilog language it supports looks useful for when you want to make a pipelined design later.

+1 to Ben Eater! His videos helped me so much during university, it was like finding real gold between fool's gold.

#8This gets brought up every time the topic shows up but https://www.nand2tetris.org is a course that abstracts how a computer works, and is worth checking out

#10Wait we get 64bits risc-v on par with x86_64 on the desktop and arm64 on the mobile...
Oh, and what was done, it would be illegal with x86_64 and arm64 as you would have to pay a license in some countries... once you want to make money out of it.
