Describe in words (or C-like pseudo code) the function of the instruction xyzzy $rt,$rs. Then,assuming that a memory load request takes 5 clock cycles to complete (after MEMread has been issued), how many clock cycles would it take to execute each xyzzy instruction? In any case, give and briefly explain your answer.
