I am working on a 4 bit bidirectional shift register for some homework. It needs to have several features, one of which is the ability to do a 2 bit arithmetic shift right. I know how to do this with 1 bit, but how do you do 2? Can someone give me an example of what this would look like with numbers and then how you would implement that? By the way, the circuit we are dealing with consists roughly of 4 mux's with their outputs to 4 flip flops. If you need more details, let me know.
