What is the function of the processor register?

Registers are small amounts of high-speed memory contained within the CPU. They are used by the processor to store small amounts of data that are needed during processing, such as: the address of the next instruction to be executed.

What are the four types of registers?

Different Types of Registers

• MAR Register. The full form of MAR is the memory address register.
• MDR. The full form of MDR register is a memory data register.
• MBR. The full form of MBR is the memory buffer register.
• PC. The full form of PC is the program counter register.
• Accumulator.
• Index Register.
• Instruction Register.

What is processor register and how do you measure it?

The processor registers are generally measured in terms of bits to determine the amount of data they can hold. For example, the two most frequently used terms, 32-bit processor’ and 64-bit processor, generally refer to the size of the register on the processor.

Which register is a processor register?

Following is the list of some of the most common registers used in a basic computer:

What is register and its types?

A register is a temporary storage area built into a CPU. Most modern CPU architectures include both types of registers. Internal registers include the instruction register (IR), memory buffer register (MBR), memory data register (MDR), and memory address register (MAR).

What does it mean to have a processor register?

What Does Processor Register Mean? A processor register is a local storage space on a processor that holds data that is being processed by CPU. Processor registers generally occupy the top-most position in the memory hierarchy, providing high-speed storage space and fast access to data.
