基于先进精简指令集计算机设计的采集及大容量存储

Study on Data Collection and Large Capacity Storage Based on ARM

针对炮车及步兵战车、坦克等车载系统多传感器信息采集采样速度与闪存编程速度不匹配及大容量存储的问题,提出基于先进精简指令集计算机设计(ARM)结合大容量的闪存构建车载信息采集及大容量系统,采用双口的RAM作为高速缓存的方式取代了直接对闪存进行编程的传统方法,使用流水线技术提高闪存的写入速率,实现数据采集的大容量存储。

Aimed at the problems between high speed data collection and slow program flash memory and the large capacity storage charactoristic for data collection with multisensors-mounted, on cannon, chariot and tank, a data collection system with mass storage is designed,based on ARM and high density flash memory. In this paper, pipelining technology accompanied with dual RAM as cache, instead of direct program operation, is utilized to improve program speed.
