基于FPGA的智能分区存储系统设计

常规炮弹于恶劣环境下，内部信号采集处理系统存在意外瞬时掉电的情况。针对掉电情况下数据存储错误的问题，提出了一种基于FPGA的智能分区存储方法，在研究NAND Flash读写、擦除和存储的特点的基础上，设计了一种智能分区存储系统，实现了存储数据开始地址的智能检测及断电自动跳址开始下一次数据的续存。实弹试验证明，该系统提高了FLASH存储区域的利用率，有效的解决了数据存储系统在常规弹药制导化应用过程中的实际问题。

Designing of Intelligent Control for Data Acquisition System Based on FPGA

If conventional projectile in the harsh conditions, data errors would happen when editorial system instantaneous power off in accident, so an intelligence partition storage technology of recorder in ammunition was presented based on FPGA. Memory read and write, erase, storage characteristics of NAND Flash was studied at previous, the function that intelligent detection of address for data storage every time and automatic jump to next address without manual operation was brought about at this system. It has proved in projectile experiments, the system improved storage area utilization of flash memory effectively and solved the practical problems in the process of application that data storage in conventional munitions guidance.
