2013-07-01x86: lpc: fix a segfault in av_evaluate_lls_sse2()Loren Merritt
2013-06-29lpc: use levinson for the first pass of multipass choleskyLoren Merritt
Levinson is faster, and cholesky is only needed if we want to apply different weights to different samples, which doesn't happen on the first pass. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
2013-06-29x86: lpc: simd av_update_llsLoren Merritt
4x-6x faster on sandybridge Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
2013-06-29lpc: use function pointers, in preparation for asmLoren Merritt
Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
2013-06-29lpc: remove "decay" argumentLoren Merritt
We never used the rolling-average mode, and this makes av_update_lls 15% faster. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
2013-02-28lls: move to the private namespaceLuca Barbato
The functions are private.

Rename the called dsp init functions to *_init_x86.
2012-08-23lpc: fix alignment of windowed samples for odd maximum LPC orderJustin Ruggles
Fixes crash on x86 due to alignment requirements for w_data in lpc_apply_welch_window_sse2().
