[alsa-devel] Extern dsp device
Hi everybody,
In my bachlor project im planing to realise an outboard fpga dsp device connected by gbit ethernet and driven by alsa.
The idea: computer system with linux rt kernel, extra gbit ethernet if and for example rme hdsp 9652 audio if. Outboard fpga with gbit if and DSP routines (PureD ata Engine?)
Now the fpga board is connected via gbit eth, the kernel gets it and inserts the gbit ethernet card into the audio signal path. Managed with and alsa driver, cooperating with the snd-rme9652. With a gui sending OSC to the fpga board, controlling the dsp.
Goal: zero-latency routing and dsp
Do you think this strategy might work?

This is far from being zero latency. Why don't you connect the FPGA to the ADAT ports where you can work with the audio data on a proper level. You can still control the FPGA via Ethernet.
Besides, what would be the practical use of such a plug-in-device?

Hi,
The practical use would be the processing of the IOs of the soundcard in live performances.

Machines can do the work, so people have time to think. public key DA43FEF4 x-hkp://wwwkeys.eu.pgp.net _______________________________________________ Alsa-devel mailing list Alsa-devel@alsa-project.org http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
