What does each register do in assembly?

To speed up the processor operations, the processor includes some internal memory storage locations, called registers. The registers store data elements for processing without having to access the memory. A limited number of registers are built into the processor chip.

What are the different registers in assembly language?

They are grouped into several categories as follows:

  • Four general-purpose registers, AX, BX, CX, and DX.
  • Four special-purpose registers, SP, BP, SI, and DI.
  • Four segment registers, CS, DS, ES, and SS.
  • The instruction pointer, IP (sometimes referred to as the program counter).
  • The status flag register, FLAGS.

What are different types of registers explain their functions?

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

Register Symbol Function
Accumulator AC Processor register
Instruction register IR Holds instruction code
Program counter PC Holds address of the instruction
Temporary register TR Holds temporary data

What are general registers?

General purpose registers are used to store temporary data within the microprocessor. It is of 16 bits and is divided into two 8-bit registers BH and BL to also perform 8-bit instructions. It is used to store the value of the offset.

What are the different types of registers?

Different Classes of CPU Registers

  • Accumulator: This is the most frequently used register used to store data taken from memory.
  • Memory Address Registers (MAR):
  • Memory Data Registers (MDR):
  • General Purpose Registers:
  • Program Counter (PC):
  • Instruction Register (IR):
  • Condition code register ( CCR ) :

How many types of registers are *?

3. How many types of registers are? Explanation: There are 4 types of shift registers, viz., Serial-In/Serial-Out, Serial-In/Parallel-Out, Parallel-In/Serial-Out and Parallel-In/Parallel-Out.
