A method and system for reducing power supply noise comprising receiving a primary data stream at a data rate. The primary data stream comprises a stream of bits having logical values of either zero or one. Then, splitting the primary data stream to create a first group of lower rate data streams and a second group of lower rate data streams. Processing the second group of lower rate data streams to invert the logic values of the bits of the lower rate data streams to create processed lower rate data streams. The first group of lower rate data streams are combined with the processed lower rate data streams to create a complementary data stream. Then, processing the primary data stream and the complementary data stream concurrently with a data processing system, the concurrent processing reducing noise on the power supply.
