摘要:
描述了一种基于CPCI的高速固态存储板卡的设计和实现.该存储卡用于某项目中频采样存储设备上,提供中频信号的采集存储、回放及分析等功能.该存储板卡采用NAND Flash作为固态存储体,利用FPGA作为固态盘的存储控制器,同时采用文件的方式对数据进行管理.本设计采用了一种建立有效块表的方式对坏块进行管理,并通过DDR2作为坏块数据备份,进一步提高了存储时的写入速度.该存储卡数据写入速度理论上可达2GB/s,可以兼容多个应用场合,实际中频存储设备只用到了500MB/s,存储容量高达768GB
Abstract:
This paper describes the design and implementation of a high speed storage system based on CPCI, which provides data storage, process and replay analysis service during the intermediate frequency sampling procedure. The storage system is composed of two main parts, i.e. NAND Flash as its static memorizer and FPGA as its storage controller, and it already functions on XX intermediate frequency sampling project. The writing speed for data storage is further increased to 2GB/s, while 500MB/s is good enough to meet the project ’s need. The total storage volume reached 768GB and it is capable to work in multiple applications as well. The paper provided several methods to meet such improvements as in managing the data in file format, managing the bad block by effective block in the mean time using DDR2for data backup
