What are general purpose computer registers?

Answer 1

Ans:- Register is synchronous circuit thus all flip-flops are controlled by a common clock line.

There is four type of Register:

(i) Serial input, serial output (SISO)

(ii) Parallel input, serial output(PISO)

(iii) Serial input, parallel output(SIPO)

(iv) Parallel input, parallel output(PIPO)

Answer 2

In computer architecture, a processor register is a small amount of storage available on the CPU whose contents can be accessed more quickly than storage available elsewhere. Most, but not all, modern computer architectures operate on the principle of moving data from main memory into registers, operating on them, then moving the result back into main memory-a so-called load-store architecture. A common property of computer programs is locality of reference: the same values are often accessed repeatedly; and holding these frequently used values in registers improves program execution performance. Processor registers are at the top of the memory hierarchy, and provide the fastest way for a CPU to access data. The term is often used to refer only to the group of registers that are directly encoded as part of an instruction, as defined by the instruction set. More properly, these are called the "architectural registers". For instance, the x86 instruction set defines a set of eight 32-bit registers, but a CPU that implements the x86 instruction set will often contain many more registers than just these eight.

Answer 3

A GPR is a register which can hold EITHER data or instructions. Registers are dedicated memory storage areas inside the CPU itself and are used for carrying out immediate instructions, passing data, or receiving immediate results from a function.
