PCIe Hard core和SG-DMA整合 - PCIe Hard core和SG-DMA整合我的系统中现在使用的是hard PCIe，接口是 AVMM with DMA。系统想提高数据吞吐率，想使用PCIe AVMM Hard core接口和SG-DMA整合，请问有没有这样的测试用例可以参考？使用SG-DMA是否一定要开启NIOSII？ Replies: Re: PCIe Hard core和SG-DMA整合 If further support is needed in this thread, please post a response within 15 days.

Replies: Re: PCIe Hard core和SG-DMA整合 Hi This is not necessary to have NIOS in the design, the DMA descriptor controller can use PCIe BAR to configure. The PCIe IP for Arria 10 or Stratix 10 comes with the embedded DMA. If this does not meet your requirement, then you have to build your DMA controller. And yes, you can use the SGDMA to build your custom DMA controller, but there is no example design available. Regards -SK
