Question

1. For the MIPS assembly instructions below, what is the corresponding C statement?

max:                   

lw          $t0, 0($a0)         #load the first array value into $t0

addi      $t1, $0, 1            #intialize the counter to one

loop:                  

beq       $t1, $a1, exit     #exit if we reach the end of the array

addi      $a0, $a0, 4         #increment the pointer by one word

addi      $t1, $t1, 1          #increment the loop counter

lw          $t2, 0($a0)         #store the next array value into $t2

slt          $t3, $t0, $t2      

beq       $t3, $0, end_if  

add       $t0, $0, $t2        #found a new maximum,store it in t0

end_if:               

j             loop      #repeat the loop

exit:      

Answer 1

int a =arr[0];
   int i=1;
   for(i; i<sizeof(arr)/sizeof(arr[0]); i++)
   {
       int b=arr[i];
       if(a<b) //compare next element in the array
           a=b;//our new maximum value
   }
