Problem 2 For this problem you are to use the code below that implements a loop. Let us assume that the code is loaded onto the memory starting at location Ox08000 (Ox means that the number that follows is hexadecimal). Please determine the format of each instruction, its location in memory, and its code. Use the table below Iw ori $a3, $0,8 $a1, 32($t2) sum: bne $a3, $0, sum_xt sub $5, $5, $7 addi $8, $7,-4 sum sum_xt: lui $4, 1025 Instruction Format Address Instruction code (Hexadecimal notation) (Hex) oprsrtrd shamt funct 0x8000 d 107 8 ori $a3, $0, 8 lw $a1, 32($12) bne $a3,$0, sum_xt sub $5, $5, $7 addi $7, $7,-4 j sum lui $4, 1025 0/24hex (4) Shex jr 24hex finex 0/25 hex MIPS Reference Data Card (Green Card") 1.
