基于铁电存储器的弹载数据高速存储系统研究

Research on Missile-Borne High Speed Data-Storage System Based on Ferroelectric RAM

针对某型弹道修正弹测试外弹道数据的需要,设计了弹载高速数据存储系统.系统采用铁电存储器(FRAM)作为数据存储载体,以TI公司DSP微控制器作为核心控制芯片.针对GPS接收机帧数据协议及传输特点,设计了包含基于中断的环形缓冲区以及数据检测校验模块的控制程序,确保数据准确接收.试验表明,铁电存储器容量大,存取速度快,整个系统工作稳定可靠,满足了弹载数据实时存储的要求.

To meet the demand of measuring the exterior ballistic of a certain trajectory correction projectile, a missile-borne high speed data-storage system was designed. This system adopted Ferroelectric RAM （FRAM） as the storing medium and TI DSP chip as the core control chip. According to the characteristics and protocols of the GPS frame data, a control program including ring buffer module based on interruption and data verification module was designed, and thus the accuracy of the data accepted was ensured. The results of the experiments show that FRAM has the advantages of fast access, large capacity. The whole system works stably and reliably, and meets the requirements of missile-borne data real-time storing.
