Use of a Multiplexer to solve this problem?

[tcowlin]

Essentially, Im unsure whether or not a Multiplexer is the tool I want to use in order to solve this problem within Verilog. Basically, if the input of y is 0, 1, 8, 15 so 0000, 0001, 1000 etc, it bit shifts a 28-bit X, one time to the left, else, it shifts it two bits to the left.

My question is really, is a multiplexer a solution for this problem.

Im not looking for coded solutions, merely whether a multiplexer can be used to solve this problem, where the input is only a 28bit unsigned X and a 4bit unsigned Y.


Cheers!.

You can place embedded codes for Verilog, so you can still use the "if-else" statement for Verilog to solve your problem without the need for a multiplexer. See

it sounds like it is just a 2 to 1 mux. a 1 or 2 bit shift. all the mux will do is select which one.

Any potential clues for the gate level code required, even just a hint on how to start!

 

[tcowlin]

Bump. Any hints or tips to start perhaps It must be gate level, thus a Mux.

a mux is just 2 AND gates and an OR gate. (multiplied by the number of bits the inputs are. One set for each bit.)
