Load the address 0x12345678 into register $t0 using lui and ori instructions. Write the i-format for these two instructions, given that the opcode for lui is 0x0f and the rs field is unused. Hint: The immediate field in lui holds the upper 16 bits. Meanwhile, the opcode for ori is 0x0d, the rs and rt fields are both used. Hint: The immediate field in ori holds the lower 16 bits.
