Hi,

In SOPC Builder there are components to do this. One is the Avalon FIFO, which can be configured to have AvMM input or output and and AvST input or output.

The other is the SGDMA (Scatter Gather DMA) which can be setup to have AvMM to AvST transfers, AvST to AvMM transfers, or AvMM to AvMM transfers.
