A circuitry called instruction decoder decodes all the instructions fetched from the memory. The instructions are decoded to various signals that control other areas of CPU.
In the last step, the CPU executes the instruction. For example, it stores a value in the particular register and the instruction pointer then points to other instruction that is stored in next address location.
Registers are a type of computer memory used to quickly accept, store, and transfer data and instructions that a being used immediately by the CPU. The registers used by the CPU are often termed as Processor registers.
A processor register may hold an instruction, a storage address, or any data (such as bit sequence or individual characters).
The computer needs processor registers for manipulating data and a register for holding a memory address. The register holding the memory location is used to calculate the address of the next instruction after the execution of the current instruction is completed.
Following is the list of some of the most common registers used in a basic computer:
