* Make fixepoint.c as a shared library (libfixedpoint.a).Michael Sevakis2013-04-26
| | | | | | | Change-Id: Icc10d6e85f890c432f191233a4d64e09f00be43d Reviewed-on: http://gerrit.rockbox.org/456 Reviewed-by: Michael Sevakis <jethead71@rockbox.org> Tested-by: Michael Sevakis <jethead71@rockbox.org>
* Move fixedpoint.h to be accessible in /firmware.Michael Sevakis2013-04-10
| | | | | | | | | | Will need it soon enough. Combine the contents of all the various fixedpoint.h files. Not moving fixedpoint.c for now since I'm not sure where it should be and it causes some dependency issues. Change-Id: Ideacbca2ca78f9158c2b114b113c274f68e908d5
* Commit FS#12130 - Fix ADX decoding on 64-bit systems by Sean Bartell. Fixes ↵Michael Giacomelli2011-05-26
| | | | | | an incorrect assumption in the ADX decoder that sizeof(int) == 32 when performing fixed point math. Update comments in the fixed point library to correct this. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@29927 a1c6a512-1295-4272-9138-f99709370657
* FFT Plugin: Revamp the main code to rid it of 64-bit math. Use 32-bit ↵Michael Sevakis2010-06-02
| | | | | | kiss_fft_scalar because 16-bit integers are generally a poor choice for computation on-target. Simplify display code to speed it up. Add logarithmic frequency display (need keymappings, guessed on some). On dual-core, perform FFT on COP. Add some support function to fixedpoint.c. ... and stuff. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@26470 a1c6a512-1295-4272-9138-f99709370657

* Fixed the problems on the new version of the fire plugin (so repush it), ↵Kevin Ferrare2008-01-23
| | | | | | added new actions to the pluginlib_actions to fix the keymaps on the Sansa e200 for the clock and fire plugins. Also slightly simplified the metronome plugin's key mapping with those new actions. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@16148 a1c6a512-1295-4272-9138-f99709370657
* Revert today's fire commits because it crashed all the targets I could test ↵Marianne Arnold2008-01-22
| | | | | | with (OndioFM, M5, C250). The plugin action conversion also caused problems (e.g. in a c200 sim which was working) I couldn't control flame type and movement and couldn't exit. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@16142 a1c6a512-1295-4272-9138-f99709370657
* Fire plugin : initializes palettes with a function instead of storing them ↵Kevin Ferrare2008-01-22
| | | | | | in static arrays, changed the color LCD's palette to make it look nicer, switched the button API to the action API, reorganized code a little bit git-svn-id: svn://svn.rockbox.org/rockbox/trunk@16138 a1c6a512-1295-4272-9138-f99709370657

* plugins code cleanup : moved the duplicated fixed point table loockup based ↵Kevin Ferrare2007-07-31
| | | | | | sinus/cosinus functions to fixedpoint.c, removed the bmp size definition in the clock.c|-(useless as the size is already defined in a .h generated with every bitmaps ...) git-svn-id: svn://svn.rockbox.org/rockbox/trunk@14087 a1c6a512-1295-4272-9138-f99709370657
* Optimise EQ coef calculation routines for both speed and size. Move now ↵Thom Johansen2007-02-05
| | | | | | | | | unneeded fsqrt function to plugin fixed point library in case it'll be needed. Move all fixed point helper macros to dsp.h. Added FRACMUL_SHL macro to facilitate high-precision shifting of 64 bit multiplies and remove rounding from macsr in main thread to make this work as intended. Tested quite thorougly, but as always, be careful with your ears. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12203 a1c6a512-1295-4272-9138-f99709370657
