How do microprocessors execute instructions?

Program Execution in the CPU

1. A sequence of instructions is stored in memory.
2. The memory address wherever the first instruction is found is copied to the instruction pointer.
3. The CPU sends the address within the instruction pointer to memory on the address bus.
4. The CPU sends a “read” signal to the control bus.

What are the four steps in a machine cycle?
