Task 4 (20 points): Comparing Strings of Bits using Multiplexer You have to implement the same circuit as in Task 3, except now you are only allowed to use the multiplexer modules from Logisims Plexers library. Notice that Logisim multiplexers are the binary select variety, allow for up to 5 select bits, and can have bitwidths of up to 64. You may use more than one but the goal is to keep silicon area cost minimum. Assume that the cost of a multiplexer of bitwidth k and n select bits is proportional to 2n-1k. Hint: In the class, we showed that you can use a multiplexer with n select bits to implement any function of n inputs. Can you decompose the task into pieces so that you can implement using a bunch of multiplexers of 5 or fewer select inputs each?
