Q4. following microoperations (and the corresponding branching) to a symbolic microinstruction. Show the corresponding binary microinstruction for each valid microinstruction. If the microinstruction is not valid, Using the microinstruction symbolic language discussed in Chapter 7, convert each of the indicate that it is invalid and explain why it is invalid. Assume that these microinstructions are stored consecutively at location 0 and that the symbolic address for 64 is "EADDR". a. M[AR] + DR, AC- AC-DR (then go to the next microinstruction) b. AR DR(0-10), AC AC' (then go to the routine corresponding to the current instruction opcode) AC + AC + DR, AR-PC (then go to microinstruction at location 64 if AC is less than zero) с.
