MIPS Modify the MULTI-cycle data path by implementing the 'add to zero' instruction (addz). Below is the syntax and the encoding. The instruction below computes (t1+t2) and stores the result in register to and. also in the memory at address zero. The 'addz' instruction always uses address zero in the memory. addz St0, St1, st2 unique 12 to 0 opcode rt rd shamt funct rs a) b) c) Show how many cycles are used for the instruction and what's done in each cycle. Draw the changes on the datapath diagram. Draw the modifications to the control state machine. MIPS Modify the MULTI-cycle data path by implementing the 'add to zero' instruction (addz).
