1.2. Stratix V Hard IP for PCI Express IP Core v16.0
|For the V-Series Avalon® Memory-Mapped (Avalon-MM) DMA for PCI Express IP Core, rearchitected the Write DMA module for the 128-bit interface to the Application Layer.||Provides higher throughput for external memories.|
|For the V-Series Avalon-MM DMA for PCI Express IP Core, the 256-bit interface to the Application Layer now supports a maximum transfer size of 64 kilobytes (KB).||Large transfers require fewer descriptor table entries.|
|For the Avalon Streaming (Avalon-ST) with Single Root I/O Virtualization (SR-IOV) variant, removed support for the 128-bit interface to the Application Layer.||Beginning in Quartus® Prime 16.0, Altera recommends the 256-bit interface to the Application Layer for all new designs. If you have a mature design using the 128-bit interface, continue to use the 15.1 release. For designs in the early stages of development, Altera recommends that you move to the 16.0 software and the 256-bit interface.|
For the Avalon-ST with SR-IOV variant, changed address map for the following registers:
|If you update to the Quartus® Prime 16.0 software, you must update your hardware and software to use the new register addresses.|
