What is the shift right arithmetic instruction?
Shift Right Arithmetic
An arithmetic right shift is equivalent to dividing by a power of 2.
The power of 2 to divide by is specified by the second operand.
The value of bits that are filled in on the left are equal to the sign bit.
If the number is positive, the leftmost bits will be filled with zero.What is an example of a right shift?
If we shift 128 to the right by 5 positions, the generated output would be 23 >> 2 = 4, i.e, 23 / 2² = 23 / 4 = 6 (closest integer).
