A universal shift register can shift in both the left-to-right and right-to-left directions, and it has parallel load capability. Draw a circuit for such a shift register.
Okay, after doing some wiki'ing and some reading about shift registers I have better idea of what we're talking about, but it's still not crystal clear.
For a "parallel load capability" n-bit data items will be transmitted all at once using n seperate wires, thus the transfer is performed in parallel. Is this what I'm looking to accomplish? Or are they just trying to tell me that the shift register has the ability to accept a parallel input?
Also, if it's suppose to have the ability to shift both Left-to-Right and Right-to-Left so we must be talking about a bi-directional shift register, correct?
How do I figure out what gates/flip-flops I'm going to need for something like this?
Thanks again!
