DMA & FIR Filter, some questions.

Hello everyone, I'd like to implement a FIR filter (because it's easy to start with) in DSPBuilder. It should make use of DMA. I finally want to integrate it into an NIOS II based system using ...

Your right, what I actually want is only the DSP logic in DSPBuilder. But with the ordinary SOPC-DMA controllers I don't get the DSP logic in between.

So using the modular SGDMA the following steps should work, shouldn't they?

- Use SOPCBuilder to build a nios system

- integrate the modular SGDMA as three seperate components into SOPCBuilder (via the 'new component' dialog and setting the interfaces right)

- connect the dispatcher and the read and write masters through the command&response sinks/sources

- connect the Streaming FIR/DSP logic with the datapath by using the data source of the read master and the data sink of the write master

I wouldn't need to write any HDL, would I?
