Abstract:
1. A data transmission apparatus using a number of asynchronous dual-rail buses comprising: a compressor constructed on a transmission side of the number of asynchronous dual-rail buses for outputting an index signal and an index control signal when identical data is to be transferred, the compressor having a transmission data control unit for storing previously-transmitted data and comparing the previously-transmitted data with data to be currently-transmitted to determine if the previously-transmitted data and the data to be currently-transmitted are identical; and a de-compressor constructed on the receiving side of the number of asynchronous dual-rail buses for outputting previously-transmitted data stored in an output data control unit when the index signal and the index control signal are transferred from the compressor, the output data control unit storing the previously-transmitted data, wherein the compressor limits the number of asynchronous dual-rail buses to a predetermined number when identical data is to be transferred.
