For the following MIPS programming exercise, you may use only these instructions or macros:
add addi addiu addu and andi div divu li lui lw mfhi mflo mult multu nor or ori sll sra srl sub subu sw xor xori
Initialize register $9 to 0x7000. Shift the bit pattern so that $9 contains 0x70000000. Now use the addu instruction to add $9 to itself. Is the result correct?
Then repeat the procedure using register $10 and the add instruction. What happens?
Write a short description (2 or 3 sentences is enough) of the differences.
