Question

Write a program which will store 564AH as input number, adds the number

with 0 F557H and keeps the result in AX register. After addition it performs
rotation of AX register four times from left to right side in a particular way so that, it
will receive the previous carry flags value in each turn.

Clearly indicate the operation of the register values with proper rough work

Answer 1

To accomplish the given tasks, you can write a program in assembly language that manipulates registers and performs arithmetic and rotate operations.

Step-by-step explanation:

To write a program that performs the given tasks, you would need to use a programming language that allows manipulation of registers and binary operations. One such language is assembly language. In assembly language, you can perform arithmetic operations and rotate operations on registers. Here is an example program written in assembly language that accomplishes the given tasks:

MOV AX, 564AH ; Move 564AH into AX register
ADD AX, 0F557H ; Add the number 0F557H to AX register
ROL AX, 4 ; Rotate AX register 4 times to the left
ROL AX, 4 ; Rotate AX register 4 times to the left
ROL AX, 4 ; Rotate AX register 4 times to the left
ROL AX, 4 ; Rotate AX register 4 times to the left

After executing this program, the final value in the AX register will depend on the initial values of the registers and the carry flags. The carry flag is set when an arithmetic operation generates a carry or when a rotate operation generates a carry. By rotating the AX register 4 times to the left, the carry flag from the previous rotation will be received in each turn.
