基于Nandflash阵列的高速存储技术

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900 MB/s以上，满足高分辨率高帧频CCD相机及SAR成像存储需求。

High-speed large-capacity recording based on Nandflash arrays

The implementation of traditional recording system is introduced, also an analys is is made of the Nandflash based recording arrays implemented by FPGA, which indicates the advantage of the IP core method. The Nandflash based recording sy stem takes Fibre Channel(FC) as data input interface, CPCIE as data output inter face.Test shows the write speed of the recording system is over 900 MB/s and satis fies the recording requirement for CCD and SAR cameras with high resolution and high frame frequency.
