Assume a processor fetches the following instruction word:

000000 00000 00100 00010 00000 010100 (R-Type)

Assume the processors registers have the following values at the beginning of the cycle in which the above instruction word is fetched: (r0 = register 0, r1 = register 1, etc.)

r0: 0, r1:-1, r2:2, r3:-3, r4: 4, r5: 10, r6:6, r8:8, r12:2, r31:-16 pc = 0x04000000

Assume we are using the microprogrammed implementation with the finite state machine implementation from the slides.

What is the output from the ALU after each microinstruction?
