A register cell A is to implement the following register transfers:
AND: A + A A B
OR: A + A v B
TXR: A + B
We assume that (1) Only one of AND, OR, and TXR is equal to 1; (2) For all of AND,
OR, and TXR equal to 0, the content of A remains unchanged. Now design this register
cell directly for D flip-flops using a sequential circuit design approach. Note that TXR
represents "transfer".
