ARM: Move asm.S from libavcodec to libavutil
This will allow for easier implementation of ARM-optimized functions in libraries other than libavcodec. |

rv34: add NEON rv34_idct_add
Overall almost 4% faster, idct_add down from 350 to 85 cycles, idct_dc_add down from 83 to 30 cycles. squash: rv34 idct rearrange partial register loads |

rv34: NEON optimised dc only inverse transform
30-50% faster than the C implementation, 0.5% overall speedup on bourne.rmvb. |

rv34: joint coefficient decoding and dequantization
Perform dequantization while decoding coefficients instead of performing it on the entire coefficients buffer. Since quantized coefficients are very sparse, this usually causes a small speedup. Speedup of around 1% on Panda board compared to the removed here neon code. Global speedup is probably around 3%. Signed-off-by: Kostya Shishkov <kostya.shishkov@gmail.com> |
