【摘要】 本文提出了一种基于CMMB+DSP+FPGA架构的数字电视PMP设计方法,由移动多媒体广播接收子系统实现移动电视信号的调谐、解调,输出数字信号送给DSP解码,DSP直接将YUV420格式信号串行输出给FPGA,FPGA将YUV数据串转并,插值放大,色度转换,并采用SDRAM作为视频数据帧缓存,输出RGB数据以帧频56HZ显示于LCD显示器。该系统采用FPGA完成复杂的视频数据处理工作,降低了DSP主频使用率,增加了系统的灵活性和可扩展性。更多还原

【Abstract】 In this paper,a design method of digital TV PMP based on CMMB+DSP+FPGA architecture was presented.The mobile TV signal was tuned and demodulated by the mobile multimedia broadcasting receiver.Then the DSP decoded the digital signal and sent serial YUV420 data to FPGA,FPGA transformed the serial data to Parallel data and interpolated and converted color.Finally SDRAM was used for frame buffer,the output RGB data was displayed on the LCD monitor by the rate of 56 HZ.The system used FPGA to process complex video data,it lowered DSP frequency utilization,increased flexibility and expansibility.更多还原
