Learn How Computers Work Between Silicon and Assembly: Build a CPU with Python
summary
A hands‑on project builds a configurable CPU implemented in Python that runs a custom assembler, exposes registers and an ALU, and hooks memory and IO to callbacks and widgets; it uses 8-bit words, 256 memory addresses and a Von Neumann bus, implements microprogramming for per‑opcode step sequences, and even adds DMA with numpy based buffer. The system reaches Turing completeness with a branch‑not‑zero and running programs show register transfers, program counter jumps, and interactive I/O.
