[FFmpeg-devel] [PATCH 2/5] AAC: Compress codebook tables and optimise sign bit handling
Mans Rullgard

Mon Jan 11 13:37:46 CET 2010
The codebooks each consist of small number of values repeated in
groups of 2 or 4. Storing the codebooks as a packed list of 2- or
4-bit indexes into table reduces their size substantially, resulting
in less cache pressure.
For the band types with sign bits in the bitstream, storing the number
and position of non-zero codebook values using a few bits avoids
multiple get_bits() calls and floating-point comparisons which gcc
handles miserably.
Some float/int type punning also avoids gcc brain damage.
Overall speedup 20-35% on Cortex-A8, 20% on Core i7.
