摘　　要：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TMS320C6713B+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。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 computer 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.
