Abstract:
A semiconductor apparatus is provided herein for reducing power when transmitting data between a first device and a second device in the semiconductor apparatus. Additional circuitry is added to the semiconductor apparatus to create a communication system that decreases a number of state changes for each signal line of a data bus between the first device and the second device for all communications. The additional circuitry includes a decoder coupled to receive and convert a value from the first device for transmission over the data bus to an encoder that provides a recovered (i.e., re-encoded) version of the value to the second device. One or more multiplexers may also be included in the additional circuitry to support any number of devices.
