Question

Use 25 to 50 words to discuss one of the Shift, Rotate, Multiplication, Division Instructions and give a simple example of the .asm complete program code that you have compiled. Just keep the code simple with not much program description. Put your code in a program and make sure it compiles then copy it. Do some research, using articles other than your textbook would be great also. Please write the code s well or a screenshot also just write on any one either shift or rotate or multiplication

Answer 1

Shift Instructions : The main purpose of the shift instruction is move or shift a operand to the left or to the right bit by bit.

The shift instruction is used to move the register directly by the instructions-

1. Logical Shift Right (LSR).

2. Logical Shift Left (LSL)

3. Arithmetic shift right. (ASR)

4. Rotate right (ROR)

5. Rotate right with extend. (RRX)
