Process Design:-
Process design is used to perform different operations as well as execution and instruction. To perform these operations it uses different components.
There are basically 4 component used by a processor, they are:-
- ALU
- CU
- Bus
- Register
ALU:-
It performs different types of arithmetic and logical operation.
ALU stands for the Arithmetic and Logic Unit. It is a real workshop of the processor.
Arithmetic operations are mainly :- +, -, *, /…..etc.
Logical operations are :- logical AND, logical OR, comparision etc.
CU:-
It is a part of the CPU, which is used to co-ordinate the different operations of the system. The operations are:-
- Fetch
- Decode
- Execute
To perform these operations it uses a control signal. The control signal is normally contains timing, signal. Which are generated by the clock.
The control signal is generated by the control unit by executing micro-operations.
Bus:-
Bus is a set of wairs and cables used to transfer binary data between the components of the computer system. There are mainly 3 types of bus used by the processor:-
- Address Bus
- Data Bus
- Control Bus
Register:-
The register is a device that is used to store binary bits. Normally the register is created by using flip-flops.
A flip flop is a circulatory device that is capable of storing multiple bits at a time. The register is written according to their storing capacity.
EX :- 8bit, 16bit, 32bit.
All the register is microprocessors are synchronized using a command-click to provide faster and better results.
In processor there are 2 registers are used:-
- BUFFER REGISTER
- SHIFT REGISTER
