Dsp Workflow

[xernobyl]

I've never really coded for a DSP. Imagining I wanted to code a sound application, a synth maybe, with a few filters running on the DSP how would it work? I guess it has nothing to do with using GLSL shaders... that's the only example of using a second processor/architecture I can find.

Perhaps this will help.

Perhaps this will help.


Perhaps, if I wanted to spend one month reading tech specs and such. Is there any code sample of a simple thing using the DSP somwhere?

Yeah, a high level overview on how it would work would be cool. I'd assume you can write a DSP program in C/C++ (hopefully ) upload it to the dsp and point it at some memory to process.

I can't find any specific examples with a simple google search but surely TI has a "Getting Started" doc somewhere.

Would be a good start. C code or asm, I doubt C++ is supported. The things to look at are how the interface between the ARM and DSP is handled. i.e. how to transfer data

more specifically, there is some sample code included in
http://omapzoom.org/gf/download/frsrelease...LDP_v1.4.tar.gz
so that might give you a feel for how the DSP interfacing works at a code level.
