Problem 2 Assume that registers $80 and $sl hold the values OxD0000000 and 0x80000000, respectively. Please take into account that these are 32-bit registers a) What is the value of $to after the following MIPS instruction has been completed? Please take into account that add instruction considers the sign of integer numbers (i.e. two's complement numbers). add $t0, $50, $s1 $80: $sl: 0 0 X X D 8 0 0 0 0 0 0 0 0 0 0 0 0 0 0 b) is the result in $to the desired result, or has there been overflow? c) Let us assume that the MIPS instruction below is executed, in this case what is the value of $t0? Please take into account that subu instruction does not consider the sign of integer. subu $t0,$s0, $s1 $s 0 : $s1: 0 0 X x D 8 0 0 0 0 0 0 0 0 0 0 0 0 0 0 d) is the result in $to the desired result, or has there been overflow
