* | 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.
