8bit

These are my notes on building a 8bit computer. The circuit is simulated with the great Logisim, I've also written a converter for my assembly language and a helper to write micro instructions.

Folder structure

  • asm contains sketches and final programs written in 6502 or my own assembler.
  • circuit holds all Logisim projects, v3 is the latest.
  • microcode the microcode program for the circuits control unit (can be read, edited and saved by the microcode editor tool).
  • notes different notes on the architecture, memory organisation, opcodes etc.
  • tools small software projects to help me designing the computer.
