Question

1. MIPS assembly code:

procedure:

                  addi $s0,$zero,0

loop:

                  slti $t1, $s0, 7

                  beq $t1, $zero, exit

                  addi $s0,$s0,1

                  j loop

exit:

                  add $v0, $zero, $s0

                  jr $ra

     

What is the corresponding high-level programming language code? Write a code in your preferred language. What is the result? (5 pts)

2. Code:

int add(int a, int b) {

      return a+b;

}

int sub(int a, int b) {

      return a-b;

}

void main(){

      int x=11, y=4;

      add(x, y);

      sub(x, y);

}

     

What is the corresponding MIPS code? (5 pts)

Answer 1

1. Following image contains the explanation of mips instruction used in the above code and it's corresponding C code with in line comments.

The result is 7.

2.Following mips code perform addition and subtraction but it is performed through a function. And the value is returned in registery v0 and v1

The output will be,

V0= s0+s1

V0=11+4

V0=15

V1=s0-s1=11-4

V1=7
