What are the functions of processor rigisters?

Answer 1

Cache in a CPU is one part of the computer's memory heirarchy. The idea is that you can't have both speed and storage space; more space means slower memory. To fetch data, the CPU sends a request to RAM, which goes to the hard disk (very slow device but very large device), which fetches the data, which is then stored in RAM (smaller, but much much faster). Since that's slow (lots of buraucracy, and a slow hard disk involved), we'll keep the data in RAM. Now the next time the CPU needs that data, we can skip accessing the slow hard disk. Cache takes it one step further. Data that is frequently accessed can be stored in cache directly inside the CPU, avoiding the need to access RAM. Cache is the fastest but smallest memory in the computer. Cache registers are special locations reserved for particular purposes. What these are and what they're called depends somewhat on the architecture (Intel may not have the same registers as MIPS for example). Generally there will be some registers for storing data, storing temporary data, for function calls, arguments and returns, for the assembler, for the kernel (part of the operating system) and for the stack.

Answer 2

A register is a temporary storage location, in the processor itself, used as an intermediate result in a calculation. It can also hold special values, such as the program register, the stack register, the flags register, etc.

Answer 3

Temporary storage of data that is being worked on by the ALU between instructions. These registers are usually implemented with the highest speed memory technology in the entire computer, typically accessible in less than a single machine clock cycle.

Answer 4

the general registers are used by the programmer as storage locations and for special function.........

Answer 5

There are a few functions of the register in the CPU. Some of the functions are memory address register, memory buffer register and program counter.

Answer 6

The register is used to store temporary binary digits, including next instructions, temporary results, memory addresses and data to be processed.

Answer 7

To store small amounts of data in the short term. Registers are accessed faster than the main memory (RAM).
