摘　　要：针对雷达系统对记录设备通信带宽、容量及性能不断增长的需求,提出了一种基于Flash固态存储器设计的模块化平台管理架构。在分析地址管理和状态管理的基础上,通过设计一种缓存策略和有效流水记录方式实现高访存带宽,对比坏块处理信息形式选择合理处理方式,根据系统文件特点提出两种损耗均衡方法,并实现了单板256 Gbyte、访存带宽600 Mbyte/s的记录器产品。实验证明,设计实现的模块化平台管理架构对Flash存储器管理的有效性和可靠性有很大提升。In order to meet the growing demand of recording storage devices on communication bandwidth,capacity and performance for radar system,a module-based manageable platform architecture for Flash solid-state memory is presented. After the analysis of address management and recording flow ,designing of the cached strategy and the effective pipeline-recording mode to increase high memory access bandwidth is proposed. Then impacts of different methods of processing bad blocks ＆#39;＆#39;information are compared to select an efficient treatment. And measures to balance wear leveling in both cases measurements are made. Finally the recording board with capacity of 256 Gbyte is implemented with memory bandwidth approaching 600 Mbyte/s. The effectiveness and reliability of flash memory management are improved by the design and implementation of the management platform architecture.
