What is the single MIPS instruction or the shortest sequence of MIPS instruction

Question

What is the single MIPS instruction or the shortest sequence of MIPS instructions that performs:

c. increments register R21 by 524,298

d. clears a word at memory location 524,298

I don't know how to handle 524,298 here since it exceeds the maximum number of immediate.

Explanation / Answer

Move content of register r10 into register r22. add r22,r0,r10 Load register r15 with the value 262,145. Note: 262,145 = 2^18 + 1 = 0b100 0000000000000001 > 2^16 lui r15, 4 addi r15, r15, 1 Store the value 49,153 into a word at memory location 20000. Note: 49,153 > 2^15 and immediates can be signed. ori r15, r0, 0b1100000000000001 sw r15, 20000(r0) The equation x = y * w,assuming x, y and w are integer variables at memory location 0b10000000, 0b1001000 and 0b100010011100, respectively. lw r1, 0b1001000(r0) ; r1
