Francois-Olivier Devaux c458af9cd6 Avoided ABI breakage 2007-11-14 11:34:48 +00:00
Francois-Olivier Devaux 010ae27471 Patch by Callum Lerwick. The opj_tcd_cblk array is one of the largest allocations, because it contains a bunch of static buffers. This also makes it a major source of cache thrashing. This patch allocates the buffers from the heap, and dynamically sizes them in the decoder. I have not yet managed to dynamically size them in the encoder, getting the decoder to do it was tricky enough... I also split opj_tcd_cblk_t into separate encode and decode versions. A lot of fields were not used by both, so this cuts its size even further. 2007-11-14 10:52:02 +00:00
Francois-Olivier Devaux 24e189e4d8 Patch by Callum Lerwick. This patch rearranges the largest memory allocations so they're allocated as late as possible, and freed as soon as possible. This cuts memory usage by about half on two large test images. 2007-11-14 08:45:00 +00:00
Francois-Olivier Devaux 61a15672bb Patch by Callum Lerwick. Instead of reinventing realloc, j2k_read_sod now just uses opj_realloc in j2k.c 2007-11-14 08:29:12 +00:00
Francois-Olivier Devaux dbeebe72b9 Patch by Dzonatas and Callum Lerwick. Fp/vectorization patch which basically converts most of the irreversible decode codepath to floating point, eliminating a few rounds of int/fp conversion, resulting in a vast performance improvement, and an increase in accuracy. 2007-11-13 17:35:12 +00:00
Francois-Olivier Devaux 4bb067642f Patches from Callum Lewick: Fixed some spelling errors in dwt.c. 2007-11-08 14:29:39 +00:00
