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
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.

The patch makes integer mode work, which presumably is more efficient. If I had the manual to hand, I'd tell you exactly what I have, but I don't. Perhaps I mentioned the specs in an earlier list post. Gerv

Hi Jamey, Something's wrong with your patch. It's 146387 lines long(!!) and includes the content of many files that weren't touched. Do you have anything smaller that would include only the changes you made?

Jamey
Hi Jamey, others, Here's an updated patch for C55 that should behave better for the general case. I changed the way the option works to disable wideband so that a wideband stream could still be decoded in narrowband even with --disable-wideband. Also, I noticed you broke MAC16_16 by changing the parameter order (I don't see how you could get it to work that way), so I reverted that change. Could everyone test that patch a little bit before I check it in?

Jamey,
There is a previous posting in the speex archives with a link to the dsp c5x
patch.
Archive link:
http://lists.xiph.org/pipermail/speex-dev/2004-October/002847.html
Patch link:
http://lists.xiph.org/pipermail/speex-dev/attachments/20041029/facb8c73/spee
x-1.1.6-jeh1-0001.bin
But that patch is very different (much smaller) then the dsp c5x patch at
http://handhelds.org/~jamey/speex/speex-1.1.6-jeh2.patch.
I had appied the patch at this link:
http://lists.xiph.org/pipermail/speex-dev/attachments/20041029/facb8c73/spee
x-1.1.6-jeh1-0001.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?
Regards,
Paul

My patch to provide fixed-point support for Speex on the TI 55xx DSP is
available here:
http://handhelds.org/~jamey/speex/speex-1.1.6-jeh2.patch
The issue with codebooks that Jean-Marc mentioned is that the TI 55xx C
compiler uses two bytes per char, so codebooks take more memory than
they need to. The whole compress/decompress fit in SRAM, though, so it
probably runs faster this way and consumes less power. I did update
speex_bits to use all the bits in 2 byte chars.
If I remember correctly, that patch also enables Speex fixed-point on
Analog Devices Blackfin DSP.
Hope this is helpful. Let me know if you find any issues with the
patch. I've been working on things lower in the food chain lately so I
have not had a chance to update it.
