Justin Ruggles	94d2b0d2fd	ARM: Move asm.S from libavcodec to libavutil This will allow for easier implementation of ARM-optimized functions in libraries other than libavcodec.	13 years ago
Janne Grunau	9e12002f11	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	14 years ago
Christophe GISQUET	9ba9c34024	rv34: 1-pass inter MB reconstruction Implement 1-pass inverse transform and reconstruction for inter blocks.	14 years ago
Mans Rullgard	81dc6a2a3c	ARM: rv34: fix asm syntax in dc transform functions Signed-off-by: Mans Rullgard <mans@mansr.com> Signed-off-by: Janne Grunau <janne-libav@jannau.net>	14 years ago
Janne Grunau	e1e369049e	rv34: NEON optimised dc only inverse transform 30-50% faster than the C implementation, 0.5% overall speedup on bourne.rmvb.	14 years ago
Christophe GISQUET	98f24ecd6c	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%.
