*! DESCRIPTION: Generation and handling quantization tables: * @brief This module handles quantization tables.
*! - direct - to be included in the JPEG headers and *
*! - reverse - to go to the FPGA. Reverse are calculated as 0x10000/direct * This modules handles quantization tables cache in two ways. First, all compressor channels use common cache
*! Based on standard JPEG quality quantization tables, with the following differences * which saves computational time, and, second, each channel uses its own cache and its own set of parameters.
*! - FPGA uses multiplication by 65536/x instead of division by x * Current cache usage policy should be set with #set_cache_policy function. Default cache policy uses common cache.
*! - (to better handle JP4 flavors) it is possible to use Y tables for other components *
*! possibly with different quality. * Generation and handling quantization tables:
*! * - direct - to be included in the JPEG headers and
*! Quality is represented by 2-byte value. Each byte uses Y table if the value is Q<128, * - reverse - to go to the FPGA. Reverse are calculated as 0x10000/direct
*! and C table with (Q-128) if it is Q>=128. * Based on standard JPEG quality quantization tables, with the following differences
*! If the High byte is zero, it is treated as Q^0x80 (Q|=(Q^0x80)<<8) for compatibility * - FPGA uses multiplication by 65536/x instead of division by x
*! with a standard single-byte Q value * - (to better handle JP4 flavors) it is possible to use Y tables for other components
*! FPGA table accomodates 8 pairs of quantization coefficients, so software tries * possibly with different quality.
*! to reuse loaded tables when possible *
*! * Quality is represented by 2-byte value. Each byte uses Y table if the value is Q<128,
*! Copyright (C) 2008 Elphel, Inc. * and C table with (Q-128) if it is Q>=128.
