Hello, i want to use speex on a Blackfin DSP to make CELP compression I want to know how many MIPS are necessary to make Speex to work? Thanks Damien -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.xiph.org/pipermail/speex-dev/attachments/20070430/e445920e/attachment.html
Last I heard (results from David Rowe), the encoder could go as low as 25 MIPS for 15 kbps (complexity 1). I expect there's potential to reduce that to around 10-15 MIPS through better optimisation (and a better compiler).

We do have some targetted pieces of C code, that we noticed could be done better, and are in process of working on. -Robin
