随着各种高速长时间物理实验要求的不断提高,系统对高速的数据采集模块的需求也越来越高。在许多特殊应用的场合中,系统也需要对大量突发的数据进行采集处理。用FPGA实现的高刷新率高分辨率图像采集系统,用于船载雷达图像记录。该系统由AD、FPGA、SDRAM组成,AD芯片把雷达提供的以VGA接口方式给出的图像信号转换成数字信号,FPGA控制时序通过整页突发的模式写入SDRAM中,并提供了后续处理的接口。
With the continuous improvement of various high-speed and long-time physics experiments, the demand for high-speed data acquisition modules in the system is also getting higher and higher. In many special applications, the system also needs to collect a large amount of unexpected data. FPGA-based high refresh rate high-resolution image acquisition system for shipborne radar image recording. The system is composed of AD, FPGA and SDRAM. The AD chip converts the image signals provided by the radar into the VGA interface into digital signals. The FPGA control sequence is written into the SDRAM through the full page burst mode and provides follow-up processing Interface.
