Abstract:
The method for continuous synchronization of a plurality of independently clocked asynchronous data sources comprising the steps of:a) acquiring available data units from a plurality of data sources;b) determining a total number of received data units from each source;c) comparing said totals to a set of thresholds;d) transferring said acquired data units to a composite output when said totals meet the criteria established by said thresholds;e) repeating steps a-d until all data units have been acquired from said data sources;wherein an event counter which monitors the relative availability of data to be merged into the composite output stream;wherein the event counter in a two channel system counts up upon the arrival of a valid line pulse from the first data source and counts down upon the arrival of a valid line pulse from the second data source; andwherein the event counter is further defined as being preset to the midpoint of its range.
