Convert the following program procedure Into MIPS Instructio

Convert the following program procedure Into MIPS Instructions. Save the value of avg and sum into $s2 and $s3 a-16; b-32; C-64; avg = average(a, b); sum = sum (b, c); int sum (int arg1, int arg2) (return arg1 + arg2;) int average(int argl, int arg2) (int sum = arg1 + arg2; return sum/2;

Solution

Answer:
