From Silicon to Software: Building a Computer from Scratch Ever wondered how a piece of silicon can calculate complex physics or run a video game? It feels like magic, but it is actually a beautifully structured hierarchy of simple building blocks.

This content follows the "bottom-up" approach—starting from the most basic physical component (the transistor) and building up to complex software systems. logic gates circuits processors compilers and computers pdf

1. Fetch: The Control Unit copies the memory address from the Program Counter and retrieves the instruction from RAM.
2. Decode: The instruction (a binary number, e.g., 10110000) is sent to the decoder circuit. The decoder figures out what the CPU needs to do (e.g., "This is an ADD instruction").
3. Execute: The Control Unit activates the specific circuit within the ALU (e.g., the adder) and passes the data from registers to that circuit. The result is stored back in a register.
4. Store: (Often combined with Execute) The result is written back to memory or a register.
