* dcadsp: fix SSE code to not use SSE2 instructions.Hendrik Leppkes2014-04-06
| | | | | | | movq from SSE register to memory is an SSE2 instruction. Instead, use SSE movlps, which does the same thing. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* x86/dcadsp: add ff_dca_lfe_fir0_fma3James Almer2014-04-05
| | | | | | | ~10% faster than the SSE version. Signed-off-by: James Almer <jamrial@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* x86/synth_filter: compile avx and fma3 functions unconditionallyJames Almer2014-04-05
| | | | | | | Fixes compilation failures with "--disable-{avx,fma3} --disable-optimizations" Signed-off-by: James Almer <jamrial@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

| * dcadec: simplify decoding of VQ high frequenciesChristophe Gisquet2014-02-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The vector dequantization has a test in a loop preventing effective SIMD implementation. By moving it out of the loop, this loop can be DSPized. Therefore, modify the current DSP implementation. In particular, the DSP implementation no longer has to handle null loop sizes. The decode_hf implementations have following timings: For x86 Arrandale: C SSE SSE2 SSE4 win32: 260 162 119 104 win64: 242 N/A 89 72 The arm NEON optimizations follow in a later patch as external asm. The now unused check for the y modifier in arm inline asm is removed from configure.
