The plus (+) indicates a more advanced problem and the asterisk (*) indicates that a solution is available on the Companion Website for the text.
*Two register transfer statements are given (otherwise, R1 is unchanged):
(a) Using a 4-bit counter with parallel load as in Figure 1 and a 4-bitadder as in Figure 2, draw the logic diagram that implements these register transfers.
(b) Repeat part (a) using a 4-bit adder as in Figure 3 plus external gates as needed. Compare with the implementation in part (a).
