Chapter 2, Problem 2.20E

Explanation of Solution

Shortest sequence of MIPS instruction:

The shortest sequence of MIPS instruction for the given scenario as follows:

#right shift the "$t0" register

srl $t0, $t0, 11

#left shift the "$t0" register

sll $t0, $t0, 26

# "OR" operation is performed for the values

ori $t2, $0, 0x03FF

#left shift the "$t2" register

sll $t2, $t2, 16

# "OR" operation is performed for the values

ori $t2, $t2, 0xFFFF

# "AND" operation is performed for the register values

and $t1, $t1, $t2

# "OR" operation is performed for the register values

or $t1, $t1, $t0

Explanation:

• The “srl” instruction is used to shift one position right to the bit. Here the register value “$t0” is shifted 11 positions right to the bit and finally store the result in the “$t0”.
• The “sll” instruction is used to shift one position left to the bit...
