Question

Translate the following C++/Java Code snippets into MIPS. Assume readInt is some value already read from the keybaord. if (readInt > 0 && readInt < 500) {y = readInt *10;} else {y = readInt *100;} # readInt $s0 # y $s1 1i $t0 500 # 500 for if condition 1i $t1 10 # 10 for multiplication 1i $t2 100 # 100 for multiplication

Answer 1

Code:-

    .data   ##data section where variables are declared and intialized

   .text
main:
   blez $s0,ELSE   ##if conditon readInt > 0
   bge $s0,$t0,ELSE   ##if condition readInt < 500
           ##if the variable passes two of the conditions then only will read this part otherwise ELSE part

   mult $s0,$t1   ##multiplying of $s0 and $t1
   mflo $s1   ## copying the result into $s1 i.e y
   j END       ##skipping the ELSE part
ELSE:
   mult $s0,$t2   ##multiplying of $s0 and $t1
   mflo $s1   ## copying the result into $s1 i.e y

END:
   li $v0,10   ##close of the program
   syscall       ##system call
