MHz on all ARM9 and later devices. Note this is only optimized for arm9 (non-E), although it is faster on later devices. An arm9E/11 version will be needed for optimal performance on newer devices. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@28710 a1c6a512-1295-4272-9138-f99709370657

2010-11-20Commit first part of FS#11235 by Buschel and I. Improves scheduling on arm9 ↵Michael Giacomelli
for two filter macros in libmad that are almost never called. A larger speed up will be possible when the remaining ASM code is improved. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@28624 a1c6a512-1295-4272-9138-f99709370657

2010-06-11FS#11335 by me: make ARM assembly functions thumb-friendlyRafaël Carré
We can't pop into pc on ARMv4t when using thumb: the T bit won't be modified if we are returning to a thumb function Code running on ARMv4t should use the new ldrpc / ldmpc macros instead of ldr pc, [sp], #4 and ldm(cond) sp!, {regs, pc} No modification on pure ARM builds and ARMv5+ Note: USE_THUMB is currently never defined, no targets can currently be built with -mthumb, see FS#6734 git-svn-id: svn://svn.rockbox.org/rockbox/trunk@26756 a1c6a512-1295-4272-9138-f99709370657
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

2010-05-06Move c/h files implementing/defining standard library stuff into a new libc ↵Thomas Martitz
directory, also standard'ify some parts of the code base (almost entirely #include fixes). This is to a) to cleanup firmware/common and firmware/include a bit, but also b) for Rockbox as an application which should use the host system's c library and headers, separating makes it easy to exclude our files from the build. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@25850 a1c6a512-1295-4272-9138-f99709370657

2009-07-13Fix another file for r12 being a scratch register. Overlooked earlier ↵Jens Arnold
because this file used literal 'r13' instead of 'sp'. Changed 'r13' to 'sp' for consistency. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21838 a1c6a512-1295-4272-9138-f99709370657

2009-02-23Stop hiding errors by redirecting stderr to /dev/null. If we really need to ↵Daniel Stenberg
do re-introduce somewhere we should rather make it dependent on the V variable so that make V=1 would still show the error and only "normal" builds would hide it. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@20090 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

2008-06-01libmad: PP5002 does in fact profit more from -O2 than PP502x, so use it for ↵Jens Arnold
all targets. The previous check was half-baked (excluded iPod 3rd Gen only, but 1st/2nd Gen are also PP5002). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@17675 a1c6a512-1295-4272-9138-f99709370657
2008-06-01Compile libmad with -O2 for the Ipods instead of just newer PP targets. ↵Michael Giacomelli
Gives a 2% speedup on Ipods, but no change elsewhere. I've left the 3G alone, but its probably worth checking. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@17674 a1c6a512-1295-4272-9138-f99709370657

2007-07-29Revert r14050 (apart from the non-related whitespace changes) and fix the ↵Dave Chapman
S3C2440 (Gigabeat F/X) problems introduced by my r14041 commit in a slightly different way: Introduce a mad_iram.h file and centralise all IRAM-related decisions in there (similar to how Tremor does it). Now checks for CPU type (S3C2440) instead of target (TOSHIBA_GIGABEAT_F) and there is also a .ibss variable in syth_full_arm.S which shouldn't go in IRAM on S3C2440 targets.

2007-07-28FS #6705 - ARM optimisations for libmad by Tomasz Malesinski. Modified ↵Dave Chapman
slightly by me to not put code in IRAM for PP502x (it's slower), and for the mpegplayer version of libmad for PP5002 (there isn't enough room). On my ipod Color, it increases a 320kbps MP3 test file from 169% realtime to 188% realtime. Reported speedup on the ipod 3G was from 118% to 155% realtime for a 192kbps MP3. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@14041 a1c6a512-1295-4272-9138-f99709370657
