What is the purpose of general purpose registers?

The general-purpose registers are used to calculate data and store addresses. The control register is further classified into the PC (program counter) to control program progress and the CCR (condition code register) to test conditions.

What are the main functions of the registers AX BX CX DX?

BX is known as the base register, as it could be used in indexed addressing. CX is known as the count register, as the ECX, CX registers store the loop count in iterative operations. DX is known as the data register. It is also used in input/output operations.

What is general register?

When we are using multiple general-purpose registers, instead of a single accumulator register, in the CPU Organization then this type of organization is known as General register-based CPU Organization. In this type of organization, the computer uses two or three address fields in their instruction format.

What are the general purpose register in 8086 microprocessor?

General Purpose registers are used for temporary storage of data and memory access. Since the processor accesses register more quickly than memory. 8086 has four 16-bit general-purpose registers AX, BX, CX and DX. These are available to the programmer, for storing values during programs.

What are the general purpose registers in microprocessor?

Registers B, C, D, E, H, and L are general purpose registers in 8085 Microprocessor. All these GPRS are 8-bits wide. They are less important than the accumulator. They are used to store data temporarily during the execution of the program.

How many general purpose registers are used in 8085 microprocessor?

six general – purpose registers
The 8085 has six general – purpose registers to store 8-bit data; these are identified as B, C, D, E, H and L as shown in the figure. They can be combined as register pairs – BC, DE, and HL – to perform some 16-bit operations.

Which are the general purpose registers?

The general purpose registers are divided into two categories. Four registers, AX, BX, CX, and DX, are classified as data registers.
