Honored ContributorScatter-gather DMA for tse
Hi everyone, I looked into reference designs about tse(triple-speed ethernet), and I found that all these tse applications are built around NIOSII with scatter-gather DMAs. My question is...

Honored ContributorThe purpose of DMA is to avoid loading cpu with the task of transferring rx and tx data when is needed: the sgdma will take care of that, by directly placing data to and from the memory.
In the case of tse you can use it without sgdma but you need to connect it to a device with Avalon streaming interface in order to manage tx/rx data.
