How many general purpose registers in 80386?

Answer 1

There exists 4 general purpose registers in 8086 namely Ax(Accumulator),Bx(Base), Cx(Count), Dx(Data).Further these 4 registers are divided into 8 based on higher and lower bits i.e.,. AX- AH &AL, BX-BH & BL, CX- CH & CL, DX- DH& DL.

In 8086, there are 4 segment registers:

1. Stack segment

2. Code segment

3. Data segment

4. Extra segment

Answer 2

These are the AX, BX, CX, and DX registers. Each of these has a special purpose in addition to their being of general purpose. For example, CX is used as a counter in conjunction with loop instructions.

Answer 3

The general registers in the 8085 are B, C, D, E, H, and L, so there are 6. They can also be treated as 16 bit values, BC, DE, and HL, however, they are not independent. The accumulator, A, can also be treated as a general register, depending on the code design.
