Finished studying digital logic: now what?

[LordAlien]

I have almost finished studying digital logic at Play-Hookey and on other resources and now I want to know how to build my first cpu.
Does anybody here address me to the right resources ont the net, please?
Thank you!

It takes AMD and Intel about 2 years to build a CPU from ground up......They have several people working on those projects, that is if you are trying to accomplish what they do.

I designed and simulated an extremely simple RISC machine once. It had four 8-bit registers, an ALU, program counter, and 8 instructions. There was a program ROM that controled the state of the machine (I had to program this in hexidecimal).

Instructions: ADD, SUB, JGZ, MOV, LOAD, STORE, and some others I can't remember. Internally the machine had 2 busses to registers and 1 shared bus for memory addressing and data. It was connected to an 8 kb memory chip.

A simple project, but it was cool to watch it work in simulation.
