What are the different registers in an 8085 microprocessor?

Answer 1

There are 6 general purpose Registers and Two special purpose registers:

General purpose registers(8 bit basically) are B,C,D,E,H,L and SPECIAL Purpose resisters are STACK PONITER,PROGRAM COUNTER these two are 16 bit registers.

If u want make general purpose registers as 16 bit registers, the combination is BC,DE,HL these are 16 bit pair registers

Answer 2

There are three temporary registers in 8085.one is used during calculation to keep data temporary and then move it to destination and others two are 'w' and 'z' which hold address temporarily...........all these three users can't use .It is only used by processor .....

Answer 3

1.General purpose register

2.Temporary register

a)Temporary data register b)W and Z registers

3.Special Purpose register

a)Accumulator b)Flag register c)Instruction register

4.Sixteen bit register

a)Program counter b)stack pointer

Answer 4

The register names in 8085 are... 8 bit registers: A - Accumulator

F - Flags

B, C, D, E, H, L - General registers

TEMP - Only used internally - not available for general use 16 bit registers: BC, DE - General registers

HL - General register with some special uses

SP - Stack pointer

PC - Program counter

Answer 5

In an 8085, the 8-bit registers are...

A, B, C, D, E, H, L

... and the 16-bit registers are...

AF (Accumulator/Flags), BC, DE, HL, IP (Instruction Pointer), SP (Stack Pointer)

The opcode and temp register are not listed because they are not part of the "programmer's view" of the architecture. They exist, but they are only "interesting", from a hardware perspective, and they can not be independently manipulated.

Answer 6

Register in 8085 are of two types: a) General purpose registers b) Special purpose registers

Answer 7

General Purpose Register,

Index Register,

Pointer Register,

Flag Register,

Segment Register.

Answer 8

The multipurpose registers in the 8085 are B, C, BC, D, E, DE, H, L, and HL.

Answer 9

A, f, b, c, d, e, h, l, sp, pc
