* x86: lpc: fix a segfault in av_evaluate_lls_sse2()Loren Merritt2013-06-301-1/+1
|
* lpc: use levinson for the first pass of multipass choleskyLoren Merritt2013-06-291-13/+16
| | | | | | | 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>
* x86: lpc: simd av_update_llsLoren Merritt2013-06-291-1/+3
| | | | | | 4x-6x faster on sandybridge Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* lpc: use function pointers, in preparation for asmLoren Merritt2013-06-291-2/+2
| | | | Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* lpc: remove "decay" argumentLoren Merritt2013-06-291-1/+1
| | | | | | We never used the rolling-average mode, and this makes av_update_lls 15% faster. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* lls: move to the private namespaceLuca Barbato2013-02-281-4/+4
| | | | The functions are private.

* x86: call most of the x86 dsp init functions under if (ARCH_X86)Janne Grunau2012-10-081-1/+1
| | | | Rename the called dsp init functions to *_init_x86.
* lpc: fix alignment of windowed samples for odd maximum LPC orderJustin Ruggles2012-08-221-8/+7
| | | | | Fixes crash on x86 due to alignment requirements for w_data in lpc_apply_welch_window_sse2().
