1 Universal Asynchronous Receiver- Transmitter (UART)
2 (UART) Block Diagram
3 Four-Bit Bidirectional Shift Register
4 Shift Register Counters Shift registers can form useful counters by recirculating a pattern of 0 s and 1 s. A Johnson counter is an example of such a register. A 4-bit Johnson counter can be constructed using a series of D flip-flops as shown.
5 Shift Register Counter Timing Diagram The timing diagram for the 4-bit Johnson Counter (on the previous slide) is shown below.
6 Ring Counter A ring counter shifts a single 1 output from each flipflop to the next. A 10-bit ring counter is shown. The output sequence for the circuit is shown on the next slide.
7 Ring Counter Output Sequence
8 Security System with VHDL and Verilog
9 Register Stage Shift Load Bidirectional Key Terms One or more flip-flops used to store and shift data. One storage element in a register. To move binary data from stage to stage within a shift register or other storage device or to move binary data into or out of the device. To enter data in a shift register. Having two directions. In a bidirectional shift register, the stored data can be shifted right or left.
10 Quiz 1. The shift register that would be used to delay serial data by 4 clock periods is a. c. b. d.
11 Quiz 2. The circuit shown is a shift register. a. serial-in/serial-out b. serial-in/parallel-out c. parallel-in/serial-out d. parallel-in/parallel-out
