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