libavcodec: Implementation of 32 bit fixed point FFT
Iterative implementation of 32 bit fixed point split-radix FFT. Max FFT that can be calculated currently is 2^12. Signed-off-by: Nedeljko Babic <nbabic@mips.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at> |

libavcodec/mips: fix for mips optimized fp fft with hard coded tables disabled
Floating point FFT (nips optimized) breaks when hard coded tables are not enabled because MIPS optimization of floating point FFT uses only ff_init_ff_cos_tabs(16) which is not enabled by default in that case. This patch is fixing it. Signed-off-by: Nedeljko Babic <nbabic@mips.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at> |

mips: Add dependencies on HAVE_INLINE_ASM

Optimization of AC3 floating point decoder for MIPS
FFT in MIPS implementation is working iteratively instead of "recursively" calling functions for smaller FFT sizes. Some of DSP and format convert utils functions are also optimized.
