Write MIPS instruction sequences to perform the following operations.

Do not use pseudoinstructions.

In addition to OR, ORI, AND, and ANDI, the MIPS ISA also has NOR (R-Type), XOR (R-Type) and XORI (I-Type). Make the best use of all logical instructions.

For full credit you must use a minimum length sequence.

HINT: QtSPIM can be used to check the correctness of your sequences, but no QtSPIM program is required.

For each operation, the input and output register is specified. Use the $t registers if other registers are needed.

Extract byte 2 (bits 16 to 23) of the value stored in $s0, placing them in the low order byte (bits 0 thru 7) of $s1.

Clear bits 12 thru 15 of $s0 (modify $s0 in place). Leave the other bits unmodified.

Set bits 22 and 23 of $s0 (modify $s0 in place). Leave the other bits unmodified.

Invert the even bits (bit 0,2,4,6,..30) byte of $s0. Leave the odd bits unmodified.

Replace byte 1 (bits 8 to 15) of $s0 with the low-order byte of $s1. Modify $s0 in place.
