Expert Solution & Answer
Chapter 2, Problem 2.19.2E
Explanation of Solution
The value of $t2:
The given is:
$t0 = 0xAAAAAAAA
$t1 = 0x12345678
sll $t2, $t0, 4
andi $t2, $t2, -1
- The “sll” instruction is used to shift one position left to the bit. Here the register value “$t0” is shifted 4 positions left to the bit and finally store the result in the “$t2”.
- The “andi” instruction is used to “AND” the constant value to the register “$t2” and store the result in the “$t2”.
Step1: Convert the hexadecimal value into the binary value
Step2: Left shift the “$t0” value
Step2:
Here the first four bits removed and “0s” are added in the last 4 position.
Step3: Take 2’s complement for “-1” value.
