Nand2Tetris Unit 05 - Finalize the Computer
Task
Wire the CPU and wire the Computer together.
Blocker
Still a little bit of uneasy and just moving slow. It feels good to be unknowing. Some of these Jump bits are confusing me. The logic behind it. zr and ng.
Lesson
It suddenly clicked for me. zr & ng. zero and negative. That way we can check the jump statements. And we only actually have to create the logic for the 3 jump bits and all 8 possibilities fall into place. PC done. CPU was for sure the hardest. Computer was relatively simple. It was just wiring it together without any logic. The diagram was provided. All tests cleared. What a great feeling!
Tomorrow
