James Almer	884e085d1e	x86/synth_filter: Revert the switch to float ops with SSE2 This reverts the changes `6467209836` and `68c3ed936a` did to the SSE2 version, which generated a hit of about 5 cycles.

Christophe Gisquet	2cdbcc0048	x86: synth filter float: implement SSE2 version Timings for Arrandale: C SSE win32: 2108 334 win64: 1152 322 Factorizing the inner loop with a call/jmp is a >15 cycles cost, even with the jmp destination being aligned. Unrolling for ARCH_X86_64 is a 20 cycles gain. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Christophe Gisquet	169243112c	x86: dcadsp: implement SSE lfe_dir Results for Arrandale/Windows: 32: 1670 -> 316 64: 728 -> 298 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Christophe Gisquet	4cb6964244	dcadec: simplify decoding of VQ high frequencies 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.	11 years ago

Christophe Gisquet	5b59a9fc61	x86: dcadsp: implement int8x8_fmul_int32 For the callable function (as opposed to the inline one): C SSE SSE2 SSE4 Win32: 47 42 29 26 Win64: 30 33 25 23 The SSE version is neither compiled nor set for ARCH_X86_64, as the inlinable function takes over.
