Respond to the following:
• What is the principle of operation of a bidirectional shift register? Describe one practical application of bidirectional shift register.
• What is the principle of operation of an Asynchronous Counter? Describe one practical application of Asynchronous Counter.
Provide detailed answers to the following:
1. How many flip-flops will be complemented in a 10-bit binary ripple counter to reach the next count after (a) 1001100111; and (b) 1111000111?
2. A flip-flops has a 3 ns delay from the time the clock edge occurs to the time the output is complemented. What is the maximum delay in a 10-bit binary ripple counter that uses these flip-flops?
What is the maximum frequency at which the counter can operate reliably?
3. Write Verilog code that represents an eight-bit Johnson counter. Synthesize the code with your CAD tools and give a timing simulation that shows the counting sequence.
4. The content of a 4-bit register is initially 1101. The register is shifted six times to the right with the serial input being 101101. What is the content of the register after each shift?
5. What is the difference between serial and parallel transfer? Using a shift register with parallel load, explain how to convert serial input data to parallel output and parallel input data to serial output.
6. Write and verify the HDL behavioral description of a four-bit shift register shown below. Image of a four-bit shift register
7. Problem Statement: Write Verilog code to design a four-bit synchronous counter with parallel load using D FF.
