How CPUs Work in 5 Days

Free 5-day course on CPU internals. Transistors, logic gates, ALU, instruction execution, and modern CPU design.

  • Build logic gates from transistors and see how AND/OR/NOT create all computation
  • Understand the ALU: how it adds, subtracts, compares, and sets status flags
  • Master the register file: 16 general-purpose x86-64 registers and how they're used
  • Trace a single instruction through fetch, decode, execute, memory, and writeback
  • Understand multi-core, HyperThreading, Turbo Boost, and power management
