基于FPGA的色彩空间转换系统设计

Design of Digital Video Processor System on FPGA

对TVP5150视频解码器输出的ITU-R BT.656格式数据,采用Xilinx公司Virtex-4系列的FPGA作为主控芯片,设计了一种色彩空间转换系统,重点描述了系统的整体设计、TVP5150芯片的配置和FPGA内部色彩空间转换系统的设计,包括解交织模块、串并转换模块、颜色空间转换模块、帧缓存模块和VGA时序和控制模块,完成了从YCbCr信号到RGB信号的转换,并使用ADV7123视频D/A转换芯片转换后通过VGA显示出来。

On the TVPS150 video decoder output of ITU-R BT.656 format data, the Xilinx Virtex-4 series of FPGA chip are used as the master to design a color space conversion system. Focus on describing the system＇s overall design, TVPS150 chip configuration and the internal color space conversion system design of FPGA are introduced, including the solution of mixed module, string and converted to the module, color space conversion module, modules and VGA frame buffer timing and control module. The signal conversion from the YChCr to RGB signal is made. The ADV7123 video D/A conversion chip is used and converted through the VGA display.
