Look for the best fastest way Avalon streaming

Hi there, I'm looking for the best fastest way of Avalon stream (Avalon-MM/ST, Source/Sink), because I need fast streaming of SDR data). Does anybody have a simple sample like megacore FFT/FI...

Your fastest method would be to build your own DMA controller to read/write directly to the SDRAM. However, that's a significant effort. So the next best would be to use the SGDMA controllers and use Avalon-ST interfaces to get the data to/from the SGDMA controller.

A simple example is the Triple-speed ethernet reference design.
