摘要
采用了32位微控制器TSK3000A、通用Wishbone总线规范IP核和BT656视频标准等。在FPGA软核设计时,采用了基于Openbus总线的系统设计方式,利用NB2开发验证平台,在Xilinx公司的Spartan-3系列FPGA芯片上下载实现,并接入平台进行验证。该设计的系统可以将输入的模拟视频信号处理之后显示在TFT真彩LCD屏上,图像清晰,系统稳定,可移植性好。
A video capture system IP core is designed in this paper. TSK30OOA, wishbone bus IP core and BT656 video stardard are used in the design. FPGA soft core is designed base on Openbus. Then use NB2 platform and download the IP core to Xilinx Spartan-3 series FPGA. The system designed that can show process simulate video signal, and show clearly on TFT LCD. The design is stable, and can be transplanted.
