A sequential circuit has one input (X), a clock input (CLK), and
two outputs (S and V). X, S and V are all one-bit signals. X
represents a 4-bit binary number N, which is input least
significant bit first. S represents a 4-bit binary number equal to
N + 3, which is output least significant bit first. At the time the
fourth input occurs, V = 1 if N + 3 is too large to be represented
by 4 bits;...

2) (10 points) Consider a microprocessor driven by an 8-MHz input clock, with a 16-bit external data bus. Assume that this microprocessor has a bus cycle whose minimum duration equals 4 input clock cycles. A bus cycle is the number of clock cycles required to accomplish a task (such as data transfer). What is the maximum data transfer rate across the bus that this microprocessor can sustain, in bytes?
