* avcodec/mpegaudio_tablegen: speed up dynamic table creationGanesh Ajjanagadde2015-12-011-0/+1
| | | | | | | | | | | | | | | | | | | This does some miscellaneous stuff mainly avoiding the usage of pow to achieve significant speedups. This is not speed critical, but is unnecessary latency and cycles wasted for a user. All tables tested and are identical to the old ones (bit-exact even in floating point case). Sample benchmark (x86-64, Haswell, GNU/Linux): old: 102329530 decicycles in mpegaudio_tableinit, 1 runs, 0 skips new: 34111900 decicycles in mpegaudio_tableinit, 1 runs, 0 skips Reviewed-by: Ronald S.

| * mpegaudio: add _fixed suffix to some namesMans Rullgard2011-05-171-2/+2
| | | | | | | | | | | | | | | | This adds a _fixed suffix to the fixed-point versions of things with both float and fixed-point variants. This makes it more consistent with other dual-implementation things, e.g. fft. Signed-off-by: Mans Rullgard <mans@mansr.com>

* tablegen: implement and use WRITE_ARRAY macrosDiego Pettenò2010-06-271-23/+6
| | | | | | | | | Two macros (WRITE_ARRAY and WRITE_ARRAY_2D) take the prefix (modifiers) (not all tables are static, and they might not be constant either), the type, and the name of the array. It'll be copied with same name and type, and with the correct size of the currently-defined object. Originally committed as revision 23821 to svn://svn.ffmpeg.org/ffmpeg/trunk
* tableprint: use the type name as-is for the functions' names.Diego Pettenò2010-06-271-4/+4
| | | | | | | | This drops one parameter from the functions' macros, and require structures to be typedeffed, but ensures that it is possible to map 1-to-1 the type to the function name. Originally committed as revision 23820 to svn://svn.ffmpeg.org/ffmpeg/trunk
