| 摘 要： | 航测图像具有分辨率高、数据量大等特点,为了将高帧频、高分辨率CCD相机的航测图像数据实时存储下来,当前的多PC机并行存储方法,已无法满足实时存储的要求,根据串行硬盘接口SATA协议,在可编程逻辑门阵列FPGA内实现了一种CCD图像数据的高速实时存储方案.此方案可以将数据采集、存储集成在单片FPGA内实现.利用V5FX70系列FPGA中的高速收发器GTX实现了SATA2.6协议,单盘速度可达到94.6 MB/S,若将多个盘组成硬盘阵列RAID,可以将CCD数据并行存储到SATA硬盘上.此方案单片FPGA最多可实现16个SATA硬盘接口,具有可高速、实时、稳定、便携等优点.

| Abstract: | Since the CCD images usually possess a huge data account with high-resolution,how to store the massive image data real-timely becomes more difficult in practical implementations.A high-speed,real-time method of CCD Image data storage system is designed.Data acquisition and storage are completed in a single FPGA chip.A SATA controller is designed based on the protocol SATA 2.6and implemented by using the GTX in V5FX70,reaching a speed of 94.6MB/s single.Combining several disks to be RAID can store the CCD da... |
