Abstract
An improved hybrid flow control protocol for providing FIFO capacity to prevent overflow due to bytes arriving after the FIFO indicates it is not ready to receive any more bytes utilizes a combination of a high/low watermark and credit based system. In one embodiment, when the byte count exceed the high watermark fixed credits are sent when N bytes are pulled from the FIFO. In a second embodiment, variable credits are sent depending on the difference between the number of bytes received in and pulled from the FIFO.
