基于双DSP的惯性导航计算机平台设计

摘要

As the core of position system in chariot ,inertia navigation computer requires navigation data progressing ability with hard real-time characteristic and high precision .Design of inertia navigation com-puter platform based on dual-DSP and FPGA is described .Hardware , programmable logic and software design are introduced to explain the realization of the computer platform .To satisfying the need of system , design is accomplished focusing on characteristic of orthogonal square wave ,positive-negative pulse and synchronized square wave .It has some reference value for similar engineering design .%为满足某战车用定位定向装置向其核心部件———惯性导航计算机提出的强实时、高精度的定位和导航信息处理要求，介绍了一种采用双DSP＋FPGA的嵌入式计算机平台设计方法。从硬件设计、可编程逻辑设计、软件设计三个方面详细说明基于双TMS320 C6713 B＋FPGA的惯性导航系统计算机平台的实现。针对正交方波、正负脉冲、同步方波等惯导信号的特点展开硬件和可编程逻辑设计。从而满足了系统要求，对同类产品的工程设计具有一定的参考价值。
