Design a 4 bits Shifter.

[whoovian11]

Does anyone know how to design a 4 bits Shifter. In this circuit, you should have 4 inputs for input value, 4 outputs, and 1 input used to determine right/left shift. 0 is used to make up the missing digit. Any ideas on how to start this ???

To help I'm going to need a little more information. What are you inputting exactly? Bits? Bytes? It's hard to tell.

Example: for the input value 1010, it is 0100 after a left shift or 0101 after a right shift.
