Central Processing Unit (CPU) • The basic CPU is composed of five different elements • Each element was designed with Gates • Each Gate was made with transistors
Simple Central Processing Unit • The five basic CPU elements are: • Instruction fetcher • Instruction decoder • Registers • Arithmetic Logic Unit • Memory Unit
Instruction fetcher • Picks up the next instruction for the CPU
Instruction decoder • Implements the instruction by controlling the other hardware.
Registers • Short term memory • Holds data for processes, like adding two numbers.
Arithmetic Logic Unit • Performs arithmetic functions: • Addition, subtraction, multiplication • Logic functions like AND and OR
Memory Unit • Handles fetching and storing of data
