A funnel shifter includes an input, an output, and a multiplexer unit including a number of multiplexer levels. The multiplexer unit may perform one of a plurality of shift operations on an input value and to provide an output value in response to receiving a shift value and a shift operation value. A first multiplexer level may be configured to format and expand the input value into a larger intermediate value. At least a second multiplexer level may be configured to perform a linear shift of the intermediate value without wrapping any bits for creating the output value. At least some of the multiplexer levels may include multiplexer select signals that may be represented as a plurality of N-Nary one of N signals where N is greater than or equal to two, wherein each of the plurality of N-Nary signals being implemented on a set of physical wires.
