基于DSP和CPLD技术的捷联惯导系统小型化导航计算机的设计

Miniaturization Navigation Computer Based on DSP and CPLD for SINS

为了满足捷联惯导系统小型化应用的需要,设计了基于DSP技术和CPLD技术的小型化导航计算机。整个系统是以数字信号处理单片机TMS320LF2407A为核心的单CPU结构的计算机系统,CPLD的设计主要是实现对激光陀螺和加速度计输出信号的计数。整个系统具有结构简单、体积小、功耗低且能满足系统实时性的要求。

To adapt to the miniaturization of SINS, a miniaturization navigation computer based on the technologies of DSP and CPLD （complex programmable logic devices） is developed. The core of the computer control system with a single CPU consists of the high speed DSP singlechip computer TMS320LF2407A. The count functions of the signal of RLG and the signal of accelerometers are designed with CPLD. Thus, the system has the advantages of simple structure, smaller size and lower power consumption. And the real-time performance of the system is met.
