ABSTRACT:
In an elastic store synchronization system, failures in the slip control circuitry or the elastic store itself are determined by employing a slip maintenance circuit. To this end, parity written into the elastic store is scrambled in a prescribed manner. The slip maintenance circuit generates signals for unscrambling the read parity from the elastic store when no slip is present and to compensate the read parity in the presence of slips so that the appropriate system parity is obtained. Any resulting parity violations indicate a failure of the slip control circuitry or of the elastic store.
