Chapter 2, Problem 2.13.2E

Explanation of Solution

The range of value for $s1:

The given is:

$s0 = 128

sub $t0, $s0, $s1

Explanation:

• The “sub” instruction is used to subtracting the registers “$s0” and “$s1” values and finally stores the result in the “$t0”.
• The memory allocated to one instruction is 4 bytes.
• The range of the number can be calculated as 2^n-1, where “n” is number of bits and the value of “n = 32”.
• The range is 2³¹-1 to 2³¹ (2147483647 to -2147483648)...
