B=0, C=0
B=0, C=1
B=1, C=0
B=1, C=1
Bit storage
  • How many D flip-flops are required to store one byte of data if D flip-flops are used to build the register?
    1
  • And how many D latches are required?
    2
  • A.8
  • B.16
  • C.4
  • D.2
D latch -- D flip-flop
  • The difference between building registers with latches and flip-flops is the D latch pass through D to Q at
    1
    ,
  • and D flip-flop pass through D to Q at
    2
    .
  • A.Whenever CLK=1.
  • B.Whenever CLK=0.
  • C.The rising edge of CLK.
  • D.The falling edge of CLK.
