基于Miron NAND Flash的弹载数据记录器的设计

Design of Missile-borne Data Recorder Based on Miron NAND Flash

摘要:

为解决传统以三星NAND Flash为基础的弹载数据记录器存储容量有限、存储速度难以提升的问题,以兼容ONFI2.2协议的MT29F32G08ABAAA为存储芯片,采用高效流水线操作以及无效块管理的逻辑设计,对芯片工作模式进行合理配置,设计了新一代数据记录器；介绍了该记录器的工作特性、能够满足特殊环境要求的硬件设计和基于高效流水线操作以及无效块管理的高速逻辑设计,最终实现了写入速度为56 MB/s、存储容量为4 G的高速大容量数据记录器。

Abstract:

In order to solve the problems of limited storage capacity and low storage speed of Samsung NAND Flash-based missile-borne data recorder, ONFI2.2 protocol compatible MT29F32G08ABAAA is used as the memory chip. By using efficient pipeline operation and invalid block management and configuring the work mode of the chip reasonably, we design the new recorder . The paper introduces the characteristics of the data recorder, the hardware design cater to demands in specific environments, and the logical design based on the efficient pipeline operation and invalid block management.The new and large capacity data recorder with 56MB/s recording speed and 4G capacity is achieved finally.
