Jean: The 6711 is actually a floating point processor so it can do the
floating point without emulation. I am working on the 6416 which does
not have it. Working with fixed point may still speed things up
possibly.<br>
<br>
Muhammad: It seems like you might have to start getting into linear
assembly to speed things up. If you are serious to getting speex
working on TI DSP we should work together on the routines. <br>

<pre wrap="">Hi Muhammad,
Did you define FIXED_POINT when compiling the code? Otherwise, you'll be
using floating point emulation which is usually very slow.

<pre wrap="">Dear developers,
I am a research associate in Al-Khwarzimi Institute of Computer
Science. I am working on TI 6711 Evaluation Board. I want to
implement audio compression algorithm on this board. I have
already implemented sub-band compression on this board. But the
resultant quality is really poor. Therefore, I want to use
speex open source library for compression. The main problem
which I am facing is that when I compress a 160 samples block,
it takes almost 40 million cycles on contrary to my sub-band
algorithm which only takes 3 million cycles. So my input buffer
overflow as the data is slowly compressed. If you have
experienced any such problem, then please let me know that what
did you do to avoid it. I will be grateful to you.
