2009-06-07Convert a number of places in core and plugins to use the BIT_N() macro ↵Jens Arnold
instead of 1<<n. Speeds up things on SH1, and also reduces core binsize. Most notable speedups: 1 bit lcd driver: drawpixel +20%, drawline + 27%, hline +5%; jpeg viewer: +8% for 1/8 scaling. Other targets are unaffected. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21205 a1c6a512-1295-4272-9138-f99709370657

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

2007-02-05Optimise EQ coef calculation routines for both speed and size. Move now ↵Thom Johansen
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
