主要研究了阵列存储在遥测图像采集系统中的应用,设计了一种以CPU+FPGA为核心的图像存储转发系统,通过LVDS总线接收数字图像信号,经过阵列存储器缓存编码后,以PCM串行码的形式下传给接收机。阵列存储可以有效缓存图像数据,完成图像数据的缓存和转发功能,实现图像数据的无缝传输。
The application of array storage in telemetry image acquisition system is studied in this paper. At the same time an image data storage and transmission system based on CPU and FPGA is designed. The digital image signals which are received by using LVDS bus are transmitted ,town to sink in the form of PCM serial code after coding in the array storage. Array storage can cache image data effectively and complete the image data storage and transmit capabilities.
