Abstract
- Understand the Instruction based on the corresponding Instruction Set Architecture (ISA)
- Then decide what Register, ALU & Main Memory to enable to carry out the Operation by generating Control Signal
Components
Program Counter
- Also known as Instruction Address Register, Instruction Pointer
- Register contains the Memory Address of the next Instruction to be executed by the CPU
Terminologies
Control Signal
- Electric signals that tells CPU Datapath, Main Memory & IO Device what to do according to program Instruction
