SN54LS673, SN74LS673. The 'LS673 is a 16-bit shift register and a 16-bit storage register in a single 24-pin package. A three-state input/output (SER/Q15) port to the shift register allows serial entry and/or reading of data. USB 2.0 spec describes bit stuffing as follows, 7.1.9 Bit Stuffing A zero is inserted after every six consecutive ones in the data stream before the data is NRZI encoded, to force a transition in the NRZI data stream. An implementation, which is faithful to this description, is as follows. Combined with a shift register, bit stuff runs at bus clock.

A Johnson counter, named for Robert Royce Johnson, is a ring with an inversion; here is a 4-bit Johnson counter: Note the small bubble indicating inversion of the Q signal from the last shift register before feeding back to the first D input, making this a Johnson counter. History
 VHDL Primer at Penn State (very nice first exposure to VHDL concepts)  Supplemental material for lecture 2: lec02_supplemental_VHDL.pdf  Links related to VHDL tutorials on dejazzer's EE-478 website Lecture 3: Concepts of VHDL (from A to Z) The 74HC194 is a 4-bit bidirectional universal shift register. The synchronous operation of the device is determined by the mode select inputs (S0, S1). In parallel load mode (S0 and S1 HIGH) data appearing on the D0 to D3 inputs, when S0 and S1 are HIGH, is transferred to the Q0 to Q3 outputs.
some VHDL similar to the following: The above code is an example of how to actually create an instance of our 4-bit adder. You will cover exactly what this does in more detail later in Lab 6. For now, suffice to say that you have access to signals A, B, and Ci that correspond to the inputs to the 4-bit adder, and signals S and Co that are the
