5. IP Core Interfaces

This chapter describes the top-level signals of the Arria® 10 or Cyclone® 10 GX Hard IP for PCI Express* using the Avalon® memory-mapped interface with DMA. The Avalon® memory-mapped interface DMA bridge includes high-performance, burst-capable Read DMA and Write DMA modules. The DMA Descriptor Controller that controls the Read DMA and Write DMA modules can be included in the Avalon® memory-mapped interface DMA bridge or separately instantiated. It uses 64-bit addressing, making address translation unnecessary. A separately instantiated Descriptor Controller manages the Read DMA and Write DMA modules. This variant is available for the following configurations:

  • Gen1 x8
  • Gen2 x4
  • Gen2 x8
  • Gen3 x2
  • Gen3 x4
  • Gen3 x8
