Rename the called dsp init functions to *_init_x86.
2012-09-05Optimization of AC3 floating point decoder for MIPSNedeljko Babic
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.

Patch (mostly) by Loren Merritt Originally committed as revision 23957 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-04-20Remove explicit filename from Doxygen @file commands.Diego Biurrun
Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in. Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-03-09Replace many includes of libavutil/common.h with what is actually neededMåns Rullgård
This reduces the number of false dependencies on header files and speeds up compilation. Originally committed as revision 22407 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-03-06Move FFT parts from dsputil.h to fft.hMåns Rullgård
Originally committed as revision 22235 to svn://svn.ffmpeg.org/ffmpeg/trunk

2009-11-05Add ff_init_ff_cos_tabs function and use it in rdft.c to ensure that theReimar Döffinger
necessary ff_cos_tabs tables are initialized. Fixes issue 1507 (QDM2 broken since r20237 without hardcoded tables). Originally committed as revision 20464 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-11-04Pad ff_cos_tabs and ff_sin_tabs so that index n points to the table for n bits.Reimar Döffinger
While this "wastes" up to 2x32 bytes it makes the code slightly simpler and less confusing. Originally committed as revision 20449 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-10-15Move/add COSTABLE/SINTABLE macros to dsputil to add extern definitionsReimar Döffinger
for ff_cos_* and ff_sin_* without introducing too much code duplication. Originally committed as revision 20243 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-10-15Use hardcoded instead of runtime-calculated ff_cos_* tables ifReimar Döffinger
--enable-hardcoded-tables was used. Due to the size, the code for the tables is generated at compile time. Originally committed as revision 20232 to svn://svn.ffmpeg.org/ffmpeg/trunk

2009-09-11Prepare for optimised forward MDCT implementationsMåns Rullgård
This adds a function pointer for forward MDCT to FFTContext and initialises it with the existing C function. ff_calc_mdct() is changed to an inline function calling the selected version as done for other fft/mdct functions. Originally committed as revision 19818 to svn://svn.ffmpeg.org/ffmpeg/trunk
