*! FILE NAME : quantization_tables.c
*! DESCRIPTION: Generation and handling quantization tables:
*! - direct - to be included in the JPEG headers and
*! - reverse - to go to the FPGA. Reverse are calculated as 0x10000/direct
*! Based on standard JPEG quality quantization tables, with the following differences
*! - FPGA uses multiplication by 65536/x instead of division by x
*! - (to better handle JP4 flavors) it is possible to use Y tables for other components
*! possibly with different quality.
*!
*! Quality is represented by 2-byte value. Each byte uses Y table if the value is Q<128,
*! and C table with (Q-128) if it is Q>=128.
*! If the High byte is zero, it is treated as Q^0x80 (Q|=(Q^0x80)<<8) for compatibility
*! with a standard single-byte Q value
*! FPGA table accomodates 8 pairs of quantization coefficients, so software tries
*! to reuse loaded tables when possible

/** @file quantization_tables.c
*
* @brief This module handles quantization tables.
*
* This modules handles quantization tables cache in two ways. First, all compressor channels use common cache
* which saves computational time, and, second, each channel uses its own cache and its own set of parameters.
* Current cache usage policy should be set with #set_cache_policy function. Default cache policy uses common cache.
*
* Generation and handling quantization tables:
* - direct - to be included in the JPEG headers and
* - reverse - to go to the FPGA. Reverse are calculated as 0x10000/direct
* Based on standard JPEG quality quantization tables, with the following differences
* - FPGA uses multiplication by 65536/x instead of division by x
* - (to better handle JP4 flavors) it is possible to use Y tables for other components
* possibly with different quality.
*
* Quality is represented by 2-byte value. Each byte uses Y table if the value is Q<128,
* and C table with (Q-128) if it is Q>=128.
* If the High byte is zero, it is treated as Q^0x80 (Q|=(Q^0x80)<<8) for compatibility
* with a standard single-byte Q value
* FPGA table accommodates 8 pairs of quantization coefficients, so software tries
* to reuse loaded tables when possible
