ABSTRACT:
The present invention provides a circuit for saving overflow data within a sequence of data that are to be clocked out of a sequential storage device. The sequential storage device has a data output to clock out data in response to a flow control signal being asserted. The sequential storage device terminates this clocking out of the data in response to the flow control signal being deasserted. However, overflow data may be relinquished by the sequential storage device and clocked out of the data output even after the flow control signal has been deasserted. The circuit includes a slack register that is connected to the data output of the sequential storage device. The slack register stores the overflow data for when the flow control signal is again asserted.
