QUESTION:

Provide a minimal set of MIPS instructions that may be used to implement the following pseudoinstruction:

                                                not   $t1,   $t2                   // bit-wise invert

ANSWER:

Step 1 of 2

Consider the following pseudo instruction:

not $t1, $t2 //bitwise invert.

The operand not is used to inverteach bit of the source register and store it in the target register. But MIPS does not have the instruction “not”.
