ABSTRACT:
An integrated circuit (“IC”) with a peripheral component interconnect express (“PCIe”) has at least two data sinks (204, 206) and a data source (202) capable of providing data packets to either data sink. A switch (208) of the PCIe system includes a first buffer (226) queuing data packets for one of the data sinks and a second buffer (227) queuing data packets for the other data sink. A status detector (224) detects when the first buffer equals or exceeds a selected buffer threshold, and a status-based flow control transmitter (232) sends a data link layer packet (“DLLP”) to the status-based flow control receiver (234) of the data source to cease transmitting first data packets while continuing to transmit second data packets.
