Problem 5: (20 points) a) Design a universal shift register that satisfies the following: ( 12 points) Uses a positive edge-triggered 4 T-flip flops as internal storage Has two select bits, S, and S, to determine the shift function as follows: S. Si Function 0 0 Shift left 0 1 Shift right Load new value 1 1 Hold the state 1 0 b) Using two 4-bit binary up counters (one is shown in the figure), construct a binary counter that counts from binary 4 through binary 99. ( 8 points) Outputs A4 A3 A2 Clear Clock CP Load Count Function Count 0 Clear to 0 Load 4-bit binary counter with parallel load Clear 1 0 0 No change CP 1 1 Load input 1 0 1 Count next binary state In4 In3 In2 Inl Inputs Problem 5: (20 points) a) Design a universal shift register that satisfies the following: ( 12 points) Uses a positive edge-triggered 4 T-flip flops as internal storage Has two select bits, S, and S, to determine the shift function as follows: S.
