Synchronous communication system having multiplexed information transfer and transition phases

摘要

A communication system segment having phase multiplexing. A first communication station contains a data source which sequentially outputs a series of data signals during a series of clock periods. The data source outputs one data signal from the series during each clock period. The first communication station also contains a transition buffer which has an input connected to the output of the data source. The transition buffer has a first-in, first-out mode in which the transition buffer stores a series of Q data signals output from the data source during the most recent Q clock periods, where Q is an integer greater than zero. A second communication station contains a data receiver which sequentially inputs a series of data signals during a series of clock periods. The data receiver inputs one data signal from the series during each clock period. A communication line connects the output of the data source to the input of the data receiver. A synchronizer may be provided for synchronizing occurrences of information transfer phases of the first communication station with occurrences of corresponding information transfer phases of the second communication station to a synchronization offset X equal to the number of clock periods of the system clock by which occurrences of each phase of the second communication station lag occurrences of the corresponding phase of the first communication station.
