摘　　要：RGB,YCrCb是表示颜色时经常用到的两种颜色空间,在应用中经常需要实现它们之间的转换。在此结合FPGA运算的特点,推导出一种适合在FPGA上实现从RGB到YcrCb颜色空间转换的算法,该方法能有效节省逻辑资源。运用VHDL语言编写程序实现电路,调用DSP48 Slice模块实现乘法运算,采用流水线设计,运算速度快,实时性好,易于在实际工程中实现。RGB and YCrCb color spaces are usually used to describe color,and sometimes people need to achieve the conversion between them.A new algorithm to implement the conversion from RGB to YCrCb color space was deduced,which bases on FPGA′s characters and can effectively reduce the cost of logic resources of FPGA device.The circuit is described in VHDL language,and uses the DSP48 Slice module to implement the multiplicative calculation.The line production design is adopted.It makes the conversion velocity fast and real-time performance tetter,and it is easily applied in practical project.
