Patent ID: 8847624

Claim:
A method of operating a circuit, said method comprising: accessing a plurality of signals using a plurality of inputs of said circuit, wherein said plurality of signals is output by a plurality of logic elements, wherein said circuit comprises a plurality of outputs and a first plurality of multiplexers, wherein a first input of said plurality of inputs corresponds to a first output of said plurality of outputs, and wherein a second input of said plurality of inputs corresponds to a second output of said plurality of outputs; accessing at least one signal using a select line coupled to said first plurality of multiplexers; and performing, responsive to said accessing said at least one signal, at least one operation on said plurality of signals using said first plurality of multiplexers, and wherein said performing said at least one operation is operable to expand functionality of said plurality of logic elements, and wherein said at least one operation comprises communicating a first signal from said first input to said second output using a first multiplexer of said first plurality of multiplexers, and wherein said at least one operation further comprises communicating a second signal from said second input to a third output of said plurality of outputs using a second multiplexer of said first plurality of multiplexers.
