I saw a thread in the list archives about a speex port to TI 55x DSP. Wondering how that worked out (is working out)? Also wondering if there is a source archive for it, or if the patch in the email archives is still current, or if there's been updates. Any info appreciated. Thanks Paul

...01.bin and enabled FIXED_POINT and speex is running on dsp c5x So now I'm wondering, did I get the whole patch? Which patch is the one I should be using?

...;s VAD. - Possibly as a result of the previous point, speex_preprocess()'s VAD can get into a bad state, given an input that varies drastically in amplitude/behavior, after which point its accuracy is ruined and the only solution is to destroy/recreate the preprocess state.

The patch is still valid, though it may require minor adjustments. Although support could be improved (optimizations, codebook packing), the patch should at least allow Speex to run on a C55.

I'm finding it dificult to get the code to fit within c5x dsp, especially due to the large heap necessary for the huge allocations in nb_encoder_init and nb_decoder_init. Are the people that have this running using additonal external ram? Has anyone experimented with reducing the internal encoder/decoder stack sizes for narrow band... is there a practical minimum that is usable? Also,
