The CPU's Program Counter points to the first instruction address in RAM. The Control Unit fetches that instruction over a system bus.

An instruction is a binary word. Example (simplified 8-bit ISA): [ 4-bit opcode | 2-bit dest reg | 2-bit src reg ] logic gates circuits processors compilers and computers pdf

Maps IR virtual registers to CPU physical registers, selects concrete instructions. Example output (x86): The CPU's Program Counter points to the first

At the lowest level, computers run on electricity. Digital circuits simplify this by using two states: voltage (High/1) and no voltage (Low/0). Logic gates are the physical components that manipulate these states. Transistors as Switches logic gates circuits processors compilers and computers pdf
