[lug] DSP Chips on Linux

[stimits at comcast.net]

It has to be on a single board computer or single module computer. It would actually be nice to see something like this available for embedded systems, but I've not seen this on any so far. I have to wonder if there is a PC104 type module somewhere with this chip?

I've heard of people doing interesting things with the EMU10K1 DSP on recent soundblaster Live! cards, and those are generally well supported. Recent versions of alsa tools include an assembler for it. Those also have the advantage of being fairly common and unusually powerful for the money.

Ok, so I know I need to do audio DSP on essentially small single board computers or modules, typically ARM or Atom. I know the need to frequently change software will mean to not use FPGAs. I don't have a hard real time requirement, but short bursts of latency could really hurt, so the work the DSP chip itself can do matters. The nature of the audio itself would be at least stereo/2-channel. I'd actually prefer to have up to 8 channels so I could deal with 7.1 channel surround sound/hidef.



Does anyone here have advice one particular DSP hardware which linux does not work well with? Does anyone here have any advice on particular DSP hardware which might be well-suited?

I'm also wondering about how well this hardware might be suited for running multiple audio channels simultaneously...either through hardware support or through threads?
