Mohamed Tarek	3bbbb96395	Use codeclib's mdct in wmapro. Input coeffs to the transform needed to be scaled down first by (log2(frame_size) - 3). Increases decoding speed by 1.3MHz on PP5022 and saves ~32KB that were previously needed by the mdct tables. (FS#11511 by Buschel and myself) ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27701 a1c6a512-1295-4272-9138-f99709370657	2010-08-04 22:29:50 +00:00
Andree Buschmann	87d59ab56c	Submit part of FS#11498. Major speedup for WMA Professional on ARM and Coldfire CPUs. Introduce asm routines for multiplications, move arrays with major impact on decoding speed to IRAM. Speeds up decoding by 25% on PP5022 and 34% on mcf5249. ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27582 a1c6a512-1295-4272-9138-f99709370657	2010-07-26 21:43:07 +00:00
Mohamed Tarek	d884af2b99	Partial conversion of the wmapro decoder to fixed point arithmetic. Currently inverse quantization & rescaling, ... imdct and windowing are all in fixed point. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27302 a1c6a512-1295-4272-9138-f99709370657	2010-07-05 22:33:37 +00:00
