Ben Avison	3b5946bcce	truehd: add hand-scheduled ARM asm version of ff_mlp_pack_output. Profiling results for overall decode and the output_data function in particular are as follows: Before After Mean StdDev Mean StdDev Confidence Change 6:2 total 339.6 15.1 329.3 16.0 95.8% +3.1% (insignificant) 6:2 function 24.6 6.0 9.9 3.1 100.0% +148.5% 8:2 total 324.5 15.5 323.6 14.3 15.2% +0.3% (insignificant) 8:2 function 20.4 3.9 9.9 3.4 100.0% +104.7% 6:6 total 572.8 20.6 539.9 24.2 100.0% +6.1% 6:6 function 54.5 5.6 16.0 3.8 100.0% +240.9% 8:8 total 741.5 21.2 702.5 18.5 100.0% +5.6% 8:8 function 63.9 7.6 18.4 4.8 100.0% +247.3% The assembly version has also been tested with a fuzz tester to ensure that any combinations of inputs not exercised by my available test streams still generate mathematically identical results to the C version.

Ben Avison	b9eb03416d	truehd: break out part of output_data into platform-specific callback. Verified with profiling that this doesn't have a measurable effect upon overall performance. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
