摘　　要：介绍了传统高速存储的实现方式,分析了用Nandflash实现海量存储的优点,实现了基于Nandflash阵列的实时高速存储模块。存储模块采用光纤FC作为数据输入端,在FPGA控制下实时存储到Nandflash阵列中,并将存储的数据通过CPCIE总线下传给其他模块作实时或事后分析、判读、处理、回放。实验结果表明,基于Nandflash的存储阵列,存储速度可达到900MB/s以上,满足高分辨率高帧频CCD相机及SAR成像存储需求。The implementation of traditional recording system is introduced, also an analysis is made of the Nandflash-based recording arrays implemented by FPGA, which indicates the advantage of the IP core method. The Nandflash-based recording system takes Fibre Channel（FC） as data input interface, CPCIE as data output interface. Test shows the write speed of the recording system is over 900 MB/s and satisfies the recording re- ctuirement for CCD and SAR cameras with hie, h-resolution and hi,h-frame-frequency.
