Build a Computer from Logic Gates — From Binary to a Working 8-Bit CPU

Learn how computers work from the ground up by building your own 8-bit CPU using digital logic gates. This hands-on computer architecture and digital electronics course takes you from binary numbers, logic gates, and Boolean logic to building an ALU, RAM, ROM, control unit, instruction set architecture (ISA), and a fully functional 8-bit CPU.

If you want to understand how a CPU actually works, how machine code becomes hardware operations, and how memory, registers, ALU, control logic, and buses work together, this course gives you a complete step-by-step journey from logic gates to a working computer.

You don't need advanced knowledge of computer architecture or digital electronics. Start with the fundamentals and progressively build every major component one logic gate at a time.
