how to integrate SG-DMA into the PCIe Hard IP core with AVMM interface - how to integrate SG-DMA into the PCIe Hard IP core with AVMM interface My design is using PCIe Hard IP core with AVMM-DMA interface, but the DMA descriptor length is limited lower than 128, I want to use 256 or larger than 256, how should I do? Modular scatter-gather dma(in platform designer IP catalog) could select larger descriptor length, how to integrate SG-DMA into the PCIe Hard IP core with AVMM interface to resolve this problem, does I need open NIOS II to use the SG-DMA?

Replies: Re: how to integrate SG-DMA into the PCIe Hard IP core with AVMM interface I have checked with the team, unfortunately, there is no such example available. Thanks. Replies: Re: how to integrate SG-DMA into the PCIe Hard IP core with AVMM interface Thanks SengKok. Does there have the example design for PCIe hard core with AVMM interface using external DMA? if yes, I could replace the normal DMA to SGDMA for the fast testing. Replies: Re: how to integrate SG-DMA into the PCIe Hard IP core with AVMM interface Hi, Yes, the descriptor controller supports up to 128 descriptors, and this is unable to change to a larger number. Regarding to the modular SG-DMA, this is not necessary to use NIOS to configure. You can use any of the AVMM interfaces to configure the modular SG-DMA, for example, PCIe BAR.
