Individual Field Values

There are four fields in the instruction. We know the bit patterns that go into each field. Let us put those patterns in registers $11, $12, $13, and $14. The program starts out:

or    $25,$0,$0          # clear $25

ori   $11,$0,  # opcode

ori   $12,$0,  # operand $s

ori   $13,$0,  # destination $d

ori   $14,$0,  # immediate operand
