Learning Computer Architecture
summary
Builds teaching simulators in Erlang and TypeScript and shows what actually works: implements gates, a one‑bit ALU and a 32‑bit ALU with built‑in shifter, models buses and clocks as gen_server bus processes, writes a small bit‑operation library and custom zip for binaries, defines a 36‑bit microinstruction format, and tests via Erlang test frameworks. Finds a bug in Tanenbaum’s addition example, models synchronous load/tick phases and configurable propagation delays, and demonstrates end‑to‑end emulation of datapath and control.
