基于PowerPC硬核的片上组合导航计算机设计

Design of Integrated Navigation Computer on a Chip Based on PowerPC Embedded Processor Core

为了满足微小型组合导航系统体积小、功耗低、精度高等方面的要求,根据新的嵌入式系统开发理念,通过软硬件协同设计将整个组合导航计算机系统集成在一片内嵌PowerPC微处理器的FPGA芯片上,实现了SoPC设计。利用FPGA内部的资源实现了组合导航系统的硬件平台,并设计了运行在该硬件平台上的底层驱动程序和组合导航软件。测试结果表明系统满足设计要求。

To meet the requirement of the size, precision and power consumption of integrated navigation system, through a new method of embedded system development and hardware and software co-design, an integrated navigation system based on PowerPC embedded processor core on a FPGA chip is proposed. In this paper the hardware platform of SINS/GPS integrated navigation computer system is designed by using FPGA internal logic source. Also, the relevant driver and navigation software are designed. Test results demonstrate the correction of the design.
