2013-07-01 | x86: lpc: fix a segfault in av_evaluate_lls_sse2() | Loren Merritt | |
2013-06-29 | lpc: use levinson for the first pass of multipass cholesky | Loren 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> | |||
2013-06-29 | x86: lpc: simd av_update_lls | Loren Merritt | |
4x-6x faster on sandybridge Signed-off-by: Luca Barbato <lu_zero@gentoo.org> | |||

2013-06-29 | lpc: remove "decay" argument | Loren 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> | |||

2012-08-23 | lpc: fix alignment of windowed samples for odd maximum LPC order | Justin Ruggles | |
Fixes crash on x86 due to alignment requirements for w_data in lpc_apply_welch_window_sse2(). | |||
