| * 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.

| * dcadsp: add int8x8_fmul_int32 to dsp contextChristophe Gisquet2014-02-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | It is currently declared as a macro who is set to inlinable functions, among which a Neon and a default C implementations. Add a DSP parameter to each inline function, unused except by the default C implementation which calls a function from the DSP context. On an Arrandale CPU, gain for an inlined SSE2 function vs. a call: - Win32: 29 to 26 cycles - Win64: 25 to 23 cycles Signed-off-by: Janne Grunau <janne-libav@jannau.net>

| | | | | | | | | | | | | | | | | | | | With the current code it fails due to running out of registers. So code the store offsets manually into the assembler instead. Passes "make fate-dts". Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>
