2012-02-24SBR DSP x86: implement SSE sbr_sum_square_sseChristophe GISQUET
The 32bits targets have been compiled with -mfpmath=sse for proper reference. sbr_sum_square C /32bits: 82c (unrolled)/102c C /64bits: 69c (unrolled)/82c SSE/32bits: 42c SSE/64bits: 31c Use of SSE4.1 dpps to perform the final sum is slower. Not unrolling to perform 8 operations in a loop yields 10 more cycles. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>

Overall speedup of HE-AAC decoding 2.3x on Cortex-A8, 1.2x on A9. Signed-off-by: Mans Rullgard <mans@mansr.com>
2012-01-28aacsbr: move some simdable loops to function pointersMans Rullgard
This prepares for assembly optimisations by moving the most time-consuming loops to functions called through pointers in a new context. Signed-off-by: Mans Rullgard <mans@mansr.com>
