The Descriptor Controller controls the Read DMA and Write DMA Data Movers. It provides a 32-bit Avalon-MM slave interface to control and manage data flow from PCIe* system memory to Avalon® -MM memory and in the reverse direction.
The Descriptor Controller includes two, 128-entry FIFOs to store the read and write descriptor tables. The Descriptor Controller forwards the descriptors to the Read DMA and Write DMA Data Movers.
The Data Movers send completion status to the Read Descriptor Controller and Write Descriptor Controller. The Descriptor Controller forwards status and MSI to the host using the TX slave port.
