Nand2Tetris Unit 05 - Wiring the CPU

Task

Wire up the CPU. Try to understand it completely.

Blocker

Not quite sure how to. Must try different things along the way.

Lesson

Kind of forgot some of the material and had to go back to previous chapters to get a refresher. Did not quite get to the finish line today, but implemented the A & D Register along with the ALU. It's tough stuff. A lot of moving parts and wires to keep in check. Forgot some of the instruction meaning and the ALU control bits and when they are used. Slowly it comes together. It's kind of weird but everything I built previously in the course come together now and all the chips and implementations have important role to play.

Tomorrow

Hopefully finalize the CPU. I only need Program Counter, the output signals and then finally built the whole Computer.
