' Identify the control signals that must be asserted for each microoperation. Complete a table with the following header for each instruction: Clock cycle RTL (microoperation) Control signals Use a minimum number of clock cycles. Assume that each instruction has been fetched from program memory and is in the [R. {a} subtract {b} add immediate {C} store word
