<p class=MsoNormal>I need to shrink speex so it will fit on an embedded
processor along with some other code. The chip has only 20k of ram.
I have done some work with libspeex.dsp by removing references to all modes but
narrow band 8000 hz (submode 3). I used the defines: FIXED_POINT,
DISABLE_FLOATING_POINT_API, DISABLE_VBR. I also removed the structures
for the other submodes and the functions that they called. I reduced the
NB_DEC_STACK and NB_ENC_STACK to the smallest values and minimized the heap
based on all calls to calloc. I haven’t optimized the call stack
yet. I reduced the ram usage to around 6k. The problem is when I
added the preprocess functionality, the ram usage went to around 20k. I
need to know what can be removed or reduced from the S[eexPreprocessState
structure. The only functionality we want to use is the denoise
option. We don’t want vbr or echo cancellation. I only see
about 1k that is directly related that can be removed from the structure.
Are there any other buffers in the structure that can be removed or a way to
reduce the size of some buffers.<o:p></o:p></p>
