Abstract:
A multiplexer tree operable to control an output a sequence of data stored in a plurality of storage units in accordance with a non-linear address sequence that has less bit transition counts than a linear address sequence. The non-linear address sequence is provided to the selection inputs of the multiplexer tree and causes the levels having greater numbers of multiplexers to toggle less frequently than the levels having smaller numbers of multiplexers. The non-linear address sequence may comprise a Gray code sequence where every two adjacent addresses differ by a single bit. The non-linear address sequence may be optimized to minimize transistor switching in the multiplexer tree.
