* libavcodec: Implementation of 32 bit fixed point FFTNedeljko Babic2013-08-041-0/+5
| | | | | | | | 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>

* Optimization of AC3 floating point decoder for MIPSNedeljko Babic2012-09-051-0/+1
| | | | | | | | | | 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.
