The CCIX PCIe module (CPM) is the CCIX and the PCIe module, including DMA (QDMA), that is hardened in Versal ACAP devices.
The CPM is configured for Gen3 x8 operation, connecting to the eight adjacent GTY transceivers via the XPIPE dedicated interface as illustrated in Figure 1. The PCIe Gen3 x8 transfers data between the accelerator card. The QDMA supports memory mapped AXI operation over the Versal ACAP NoC to allow the host server initiated writes and reads to and from the hardened DDR MCs. This operation is typically known as the QDMA memory mapped operation.
