search for: nb_pitch

...i have almost 90% cpu utilisation.It was about 19 ms every 20 ms frame .Reading other posts i understood i should be waiting 60% with this core. After some research i found the main bottleneck lies in pitch calculation . The routine void pitch_xcorr(....)runs for (144-17)times and calls corr[nb_pitch-1-i]=inner_prod(_x, _y+i, len);. As i understood this is called len>>2=10 times .This function is called every 5ms.As i found out only this function needs 12 ms per 20 ms!!!!. So how is it possible to have a total utilisation of 60% with everything included.Am i missing something or doing s...

...ve me more info on this? Not sure what info will help but here it goes... I am using GCC 3.4.4 compiling ltp.c I get 8 warnings and all of them seem to be when "#define OVERRIDE_PITCH_XCORR static void pitch_xcorr(const spx_word16_t *_x, const spx_word16_t *_y, spx_word32_t *corr, int len, int nb_pitch, char *stack) " is included from ltp_arm4.h The error places the cursor on the __asm__ __volatile__ ( line in the function. I am compiling with Optimization Level 1. I did a quick google search and found this where someone else had a similar problem when switching from 3.2.3...

I am using speex on a Philips LPC2138 Arm 7 processor and have hit two compiler warnings when using FIXED_POINT and the Arm 4 asm code. In cb_search.c get a warning on the call to compute_weighted_codebook of: "passing arg 2 of 'compute_weighted_codebook' from incompatible pointer type' In cp_search_arm4.h it is defined as: static void compute_weighted_codebook(const signed
