A control unit coordinates how data moves around a cpu. The control unit coordinates how data moves around by decoding op codes for different operations in a CPU. The control unit (CU) is a component of a computer's central processing unit (CPU) that directs operation of the processor. It tells the computer's memory, arithmetic/logic unit and input and output devices how to respond to a program's instructions.
- The control unit obtains data / instructions from memory
- Interprets / decodes the instructions into commands / signals
- Controls transfer of instructions and data in the CPU
- Coordinates the parts of the CPU
