Q3. Using the microinstruction symbolic language , convert each of the following microoperations (and the corresponding branching) to a symbolic microinstruction. Show the corresponding binary microinstruction for each. Assume that the microinstructions are stored consecutively at location 0 and that the symbolic address for 64 is DONE.

a. AC AC DR, PC PC +1 (then go to the next microinstruction)

b. DR M[AR], AC 0, PCAR (then jump to the microinstruction at location 64)

c. DR AC (then conditionally branch to address location 64 if AC is zero)

d. AR DR(0-10) (then go to the routine corresponding to the current instruction opcode)
