2010-06-10Submit FS#11365. Speed up mp3 decoding on ARM processors. It is faster to ↵Andree Buschmann
use the C-implementation of dct32 compiled with -O1 as the asm implementation of dct32 compiled with -O2. Configuration for Coldfire processors is untouched. In the new configuration the stack of the COP decoding thread needs to be increased on dualcore targets. Speed is increasing by up to 0.9 MHz (-O2 against -O1 using eabi). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@26746 a1c6a512-1295-4272-9138-f99709370657

CACHE_FUNCTION_WRAPPERS and CACHE_FUNCTIONS_AS_CALL macros. Rename flush/invalidate_icache to cpucache_flush/invalidate.

2008-12-10Use cookies for thread identification instead of pointers directly which ↵Michael Sevakis
gives a buffer against wrongly identifying a thread when the slot is recycled (which has been nagging me for awhile). A slot gets 255 uses before it repeats. Everything gets incompatible so a full update is required. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19377 a1c6a512-1295-4272-9138-f99709370657

2008-09-23Simplify synchronizaton for MPA codec and make it fully atomic, let synth ↵Michael Sevakis
thread exist for life of codec, do a bit of cleanup and use number of cores do determine if it is compiled as multithread instead of CPU type. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@18573 a1c6a512-1295-4272-9138-f99709370657

2008-09-20Commit FS#9318 - MP3 synthesis filter on COP. Loads the MP3 synth filer on ↵Michael Giacomelli
to the CoProcessor on all PortalPlayer devices, resulting in an ~90% speedup according to test_codec on the Sansa. Real world improvement is somewhat less, but still considerable. Allows MP3 decoding at 30MHz without boosting, or use of more DSP/EQ with less boosting/skipping, thus improving battery life. Minor changes to mpegplayer to retain compatibility with libmad changes. Should be no significant changes for other targets or codecs. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@18557 a1c6a512-1295-4272-9138-f99709370657

2008-04-03Move audio_set_elapsed to mpa.c, as recommended by the TODO note. Please ↵Nicolas Pennequin
correct me if affecting ci->id3->elapsed directly (ie without using ci->set_elapsed) is wrong. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@16945 a1c6a512-1295-4272-9138-f99709370657

Codec API version increment was needed so update all codecs. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@16874 a1c6a512-1295-4272-9138-f99709370657

2007-02-24SWCODEC: Dsp speed optimizations. Changes for more modularity. Removal of ↵Michael Sevakis
some usless stuff. Some assembly routines for Coldfire with speed in mind over size for the outputs but the channel modes remain compact. Miscellaneous coldfire asm updates to accomodate the changes. Codec API structure version has to increase so do a full update. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12472 a1c6a512-1295-4272-9138-f99709370657
2007-02-10SWCODEC: Annoying neatness update. Use intptr_t for codec_configure_callback ↵Michael Sevakis
and dsp_configure and stop all the silly type casting of intergral types to pointers to set dsp configuration and watermarks. Shouldn't have any effect on already compiled codecs at all. Will fix any important patches in the tracker so they compile. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12259 a1c6a512-1295-4272-9138-f99709370657
2007-02-07Fix resampling clicking as much as possible at the moment. 1) Upsampling ↵Michael Sevakis
clicked because of size inaccuracies returned by DSP. Fix by simplifying audio system to use per-channel sample count from codec to pcm buffer. 2) Downsampling affected by 1) and was often starting passed the end of the data when not enough was available to generate an output sample. Fix by clamping input range to last sample in buffer and using the last sample value in the buffer. A perfect fix will require a double buffering scheme on the resampler to sufficient data during small data transients on both ends at all times of the down ratio on input and the up ratio on output. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12218 a1c6a512-1295-4272-9138-f99709370657
2006-11-26FS#6357, patch 1: let iramcopy and bss share the same space in codecs andTomasz Malesinski
plugins. Currently, in case of plugins using IRAM bss is cleared twice, once in the loader, once in PLUGIN_IRAM_INIT. For codecs, bss is cleared only during codec initialization. Also, removed double variables in codecs storing a pointer to codec_api. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11606 a1c6a512-1295-4272-9138-f99709370657
2006-11-26SWCODEC: Stop clicks between tracks when resampler is active by only ↵Michael Sevakis
switching the DSP frequency and not resetting the resampler at track boundaries. Will make sure DSP is correctly flushed at dicontinuities but don't hear any problems currently. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11600 a1c6a512-1295-4272-9138-f99709370657
2006-10-27Re-enable the currently unused and broken dithering and noise shaping code ↵Thom Johansen
already in Rockbox, and make it a user option instead of a codec-controlled option. The majority of people probably will not even hear any difference with this enabled, but feedback is welcome. Save your settings! git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11368 a1c6a512-1295-4272-9138-f99709370657
