/* Binary search huffman table HCB_5 */
Submit FS#11445. Speed up of faad (aac) decoder via several optimizations like refactoring some requantization routines, moving several arrays and code tables to IRAM, using an optimized swap32() function and inlining several huffman decoder functions. Decoding is sped up by ~10% (PP5002, PP5022, MCF5249) and ~22% (MCF5250). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27225 a1c6a512-1295-4272-9138-f99709370657
