The real-time digital color converter core for Xilinx FPGA

Summary form only given. The subject of this paper is the color converter core for a Xilinx FPGA that can be used for RGB to YUV color conversions. Luminance and color difference coded signals (YUV) are used by many component video systems. Conversion from RGB (Red-Green- Blue) is necessary to feed a device requiring YUV input. There are many converter cores but they use only constant transformation coefficients and are optimized only by one parameter i.e. maximum input data frequency. The described converter is. optimized by two parameters: 1) the required input data frequency; and 2) the minimum of hardware complexity.
