2009-07-03JPEG IDCT8 ARMv6 assembly, slight speedup vs ARMv5.Andrew Mahone

2009-07-02Core JPEG IDCT8 optimizations for ARMv5+, small optimizations for ARMv4.Andrew Mahone
git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21612 a1c6a512-1295-4272-9138-f99709370657
2009-06-28Use hand-written constants table on ARMv5+ for JPEG IDCT, and load four ↵Andrew Mahone
16-bit constants at a time with ldrd. Not useful for ARMv4, since one load per constant would still be needed, and limited range of ldrsh would force multiple copies of table. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21535 a1c6a512-1295-4272-9138-f99709370657
2009-06-27Use single-instruction shift-and-saturate in place of range_limit for JPEG ↵Andrew Mahone
on ARMv6. Only affects the 16-point horizontal-pass IDCT. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21528 a1c6a512-1295-4272-9138-f99709370657

from usat for final output. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21526 a1c6a512-1295-4272-9138-f99709370657

acctually work on the c200. (belongs to r21373) git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21381 a1c6a512-1295-4272-9138-f99709370657
2009-06-192-point and 1-point JPEG IDCT ARM assembly, remove comment in jpeg_load.c ↵Andrew Mahone
about inline asm, change loop condition to be a bit safer in case of bad values being passed. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21349 a1c6a512-1295-4272-9138-f99709370657
2009-06-19Core JPEG decoder improvements:Andrew Mahone
For >8-point vertical IDCT, transpose the coefficients while decoding them, so that the vertical IDCT can read in rows rather than columns. This improves speed a bit for this size even using the C IDCT. Remove inline ARM asm, replacing it with an external file containing pure asm IDCT functions. Add jpeg_ prefix to JPEG IDCT functions since some of them will now be visible globally. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21345 a1c6a512-1295-4272-9138-f99709370657
2009-06-14Remove explicit counter for rows/columns in IDCT, instead testing against a ↵Andrew Mahone
pointer calculated in store_row_jpeg. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21284 a1c6a512-1295-4272-9138-f99709370657
2009-06-14Adjust AC decode such that decode *always* stops before storing an unneeded ↵Andrew Mahone
coefficient. Remove extra lines from zag[] as it should not be possible to store a coefficient for k>63, even for corrupted files. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21283 a1c6a512-1295-4272-9138-f99709370657

2009-06-11ARMv4 and ARMv5 inline assembly for 4-point IDCT.Andrew Mahone
git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21256 a1c6a512-1295-4272-9138-f99709370657
2009-06-11Move +128 offset out of range_limit, and add it to the DC coefficient in ↵Andrew Mahone
each idct*h routine, for a small binsize improvement on idct4h, idct8h, and idct16h, and a negligible speed increase. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21255 a1c6a512-1295-4272-9138-f99709370657
2009-06-11Don't compensate for lack of shift in second IDCT stage, allowing ↵Andrew Mahone
quantization table to be reduced to 16-bit. Reduce IDCT workspace to 16-bit. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21254 a1c6a512-1295-4272-9138-f99709370657
2009-06-07Undo the delta on ARM but making the loop variables signed as before r21205. ↵Jens Arnold
GCC is weird... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21206 a1c6a512-1295-4272-9138-f99709370657
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
2009-06-03Don't perform YUV->RGB conversion before row output for unscaled loads of ↵Andrew Mahone
greyscale JPEG, as store_row_jpeg already does this. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21174 a1c6a512-1295-4272-9138-f99709370657

git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21092 a1c6a512-1295-4272-9138-f99709370657
2009-05-26Use pre-multiplication in scaler to save one multiply per color component on ↵Andrew Mahone
ARM and Coldfire, at the cost of an extra add/shift in the horizontal scaler to reduce values to a workable range. SH-1 retains the same basic math, as the use of 16x16->32 hardware multiplication in the earlier scaler stages saves more than removing the 32x32->40 multiply to descale output. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21091 a1c6a512-1295-4272-9138-f99709370657
