Could some electronics guru please provide some ideas/hints to my problem. I am trying to implement a parallel in serial out shift register, and having problems with implementing the serial read out part. Consider a four bit parallel in serial out shift register, and let the following word be stored 1 1 0 1. At read out time, at the end of the first clock period, 1 should appear at the output, followed by 0 at the end of the second clock period and so on. My question is how do I generate the sequencing pulses to achieve the shift. I have experimented with a barrel shifter, but have not been very successful. Any hints/ideas would be valuable. Thanks in advance for your help.
