基于SOPC高密度固态存储系统的研究与实现

Based on SOPC high-density solid-state storage system research and realization

针对磁盘及磁盘阵列无法适应冲击、振动等恶劣环境下的高速海量数据存储的需要,选用高密度FLASH卡——San-Disk的Ultra II CompactFlash(CF)卡组成阵列,采用Altera公司的软核嵌入式处理器Nios,应用SOPC技术由单一可编程逻辑器件(FPGA)取代"处理器+FPGA"的系统结构,就扩展容量、提高存储速度等关键技术进行研究,提出解决措施,并给出系统实现方案。

On account of the hard disk and hard disk array are not suitable to the use of high-speed mass storage under shock,vibration and extreme temperature conditions,based on the research of key technique of high-density solid-state storage system with SanDisk Ultra II CompactFlash （CF）card array,a concrete realization scheme of the system is proposed,which introduces SOPC technique with Ahera soft core embedded processor Nios.
