[VHDL-FPGA-Verilog] color_converter_latest.tar

Description: The main purpose of the core is a color transform tasks such as CIE XYZ<->RGB, different RGB<->RGB and RGB<->YCbCr operations. The main part of color conversions from one to another color system concludes in 3x3 matrix multiplication with vector addition. Therefore the present core performs true 3x3 matrix multiplication and vectors addition of the input data stream. In the package ccfactors_pkg.vhd presents matrixes for all of the most popular conversions. You can use these defines or type own factors. Input DATA_WIDTH is changeable and defines by the GENERIC param of the module. Precision of the matrix factors also is changeable. Default precision – 10-E6. Better than enough for color conversion tasks.
