Table below shows the ROM map of a micro-programmed control unit with four inputs (G,X,Y and Z ) using the control address register (CAR). It uses 4:1 multiplexer with Mux =00 to select input G,Mux=01 to select for input X, Mux =10 to select for input Y and Mux=11 to select for input Z. Selection of address 0 and address 1 depends on the inputs. a) If there are altogether five outputs (A,B,C,D and E ) and eight states, draw the complete block diagram of the control unit. Derive the ASM chart from the ROM map and draw the ASM chart with the corresponding state assignments (hint there should be a total of 8 states with no mealy output)
