Fast Partial Reconfiguration Over PCI Express (XAPP1338)

1.0 English

This application note shows one way to continuously stream configuration data over PCIe to saturate the ICAP. Ultimately, the highest performance solution is one that maximizes delivery bandwidth to the ICAP by sending configuration data as quickly as the silicon allows. This partial bitstream delivery must be coupled with a sequence of events before, during, and after partial reconfiguration. For more information on design considerations, see the Vivado Design Suite User Guide: Partial Reconfiguration (UG909).
