Noisy sound quality with Blackfin in WB-mode

sorry that I didn't reply for some days. Unfortunately I had some other serious
problems with my software which are not related to Speex. I hope to solve

Noisy sound quality with Blackfin in WB-mode
...s like I messed up somewhere in the lpc code. However, it seems
like your patch is also removing some code, which is probably why you
see small differences between your asm version and the fixed point.
I don't have my setup working at the moment, but could you test the
following patch:

Noisy sound quality with Blackfin in WB-mode
Hello Jean-Marc,
I disabled the Blackfin optimization functions one by one and found
the error in libspeex/lpc_bfin.h in the autocorrelation computation.
Compared to the fixed-point-variant of that function (from lpc.c),
the blackfin-code produces correct values except for the zero offset
value. Additionally, the loop after the ASM-code assigned values
(ac32) wrong to the functions output structure (ac)....
