Abstract
One or more client engines issues write transactions to system memory or peer parallel processor (PP) memory across a peripheral component interconnect express (PCIe) interface. The client engines may issue write transactions faster than the PCIe interface can transport those transactions, causing write transactions to accumulate within the PCIe interface. To prevent the accumulation of write transactions within the PCIe interface, an arbiter throttles write transactions received from the client engines based on the number of write transactions currently being transported across the PCIe interface.
