Unit V: Control Unit | BCA 5th Semester Computer Architecture Notes Pdf

The control unit (CU) is a component of a Computer's Central Processing Unit (CPU) that directs the operation of the processor. It tells the computer's memory, arithmetic/logic unit, and input and output devices on how to respond to a program's instructions. It controls on primitive operations (micro-operations).

In this “Control Unit - Computer Architecture” you will learn about following topics:

1. Introduction of Control Unit
2. Registers Involved In Each Instruction Cycle
3. Micro-Operations for Different Sub-Cycles
4. The Fetch Cycle
5. The Indirect Cycle
6. The Execute Cycle
7. The Interrupt Cycle
8. Control of Processor/CPU
9. Responsibilities of CPU
10. Functional Requirement of CPU
11. Structure of Control Unit with Control Signals
12. Types of Design Issues in Control Unit
13. Hardwired Control Unit
14. Two Main Issues in Hardwired Implementation
15. Control Unit Input
16. Control Unit Logic
17. Micro-Programmed Control Unit
18. Difference between Hardwired and Micro-programmed Control Unit
19. Types of Micro-instruction Format
20. Horizontal Micro-instruction Format
21. Vertical Micro-instruction Format
22. Difference between Horizontal and Vertical Micro-instruction Format
23. Microinstruction Sequencing
24. Microinstruction Sequencing Techniques
25. Two Address Field Microinstruction
26. Single Address Field Microinstruction
27. Variable Format Microinstruction
28. Micro-instruction Execution
