PIO performance

Hi, I use IORD and IOWR to control the PIO and it seems the speed will be no more than 15MHz. Is there any way to accelerate?

since I don't have much time to tell you.

I just tell you a point.

- SOPC builder has SG-DMA.

- SG-DMA creates Avalon-ST data stream.

- sample of DMA is in NiosII IDE template.

it may take time to learn by yourself.

but you need this skill if you need more than 100MB/sec.

I'm sorry for now.
