摘要
为了提高星载存储器的数据管理水平,应对Flash应用复杂、国内半导体工业水平较低、航天任务性能可靠性等需求提升等挑战,基于实际卫星任务需求,结合四级流水、四倍总线扩展技术,提出一种的多分区数据管理结构设计,通过分析和仿真介绍了数据流通路的特点及性能,存储器吞吐率接近1 Gbps,能够有效满足航天任务需求。同时根据典型数传系统数据处理流程,给出了此数据结构设计下由地面接收数据逆向寻址的计算方法,在实际应用中能够大大降低地面测试、数据分析工作的复杂度。
To improving data management level to deal with the complexity of Flash operations, the lack of high-level semiconductor logic devices, and the increase of performance and reliability demands, one multi-partition data management structure design for 4-pipe-line writing and fourfold bus expansion is proposed according to real space mission request. The feature of data flow is introduced by analysis and simulation. The throughput rate can reach almost 1Gbps. On the basis of design, a data reverse-addressing method is proposed to simplify the data analysis work in typical data transmission system.
