METHOD AND SYSTEM FOR CONTROLLING INFORMATION FLOW IN A HIGH FREQUENCY DIGITAL SYSTEM FROM A PRODUCER TO A BUFFERING CONSUMER VIA AN INTERMEDIATE BUFFER AND A SHARED DATA PATH

An information handling system includes a plurality of producers that output packets of information, at least one consumer of the packets, and an information pipeline coupling the consumer and at least a particular producer among the plurality of producers. The information pipeline includes a shared resource having a bandwidth shared by multiple of the plurality of producers. The information handling system further includes a control unit that regulates packet output of the particular producer and that receives as inputs a producer output indication indicating that the particular producer output a packet and a shared resource input indication indicating that a packet output by the particular producer has been accepted by the shared resource for transmission to the consumer. Based upon these inputs, a number of grant messages output to the particular producer within a feedback latency of the control unit, and a portion of the bandwidth allocated to the particular producer, the control unit whether the particular producer can output a packet without packet loss. In response to a determination that the particular producer can output a packet without packet loss, the control unit outputs a grant message to the particular producer indicating that the particular producer is permitted to output a packet.
