彩色空间转换的VHDL源代码，可以实现CIE XYZ<->RGB， different RGB<->RGB和RGB<->YCbCr之间的相互转换，使用3x3矩阵模板(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.)
