一种紧耦合Ubuntu系统的卫星导航接收机设计

提出了一种采用ARM+FPGA架构的紧耦合Ubuntu系统的卫星导航接收机的设计,ARM上运行Ubuntu系统, ARM与FPGA之间通过 ARM自带的 GPMC接口进行通信,重点解决 Ubuntu 系统与 GPMC 通信相关的驱动软件设计问题。首先介绍了 ARM Cortex A8的GPMC接口原理,然后给出了Ubuntu系统的主要软件驱动模块的设计思路。本设计结合了ARM和FPGA各自的优点,借助Ubuntu系统自身强大的功能,加快了接收机的研发速度,增加了其稳定性。

Satel l ite Navigation Receiver Design Based on Tight Coupl ing Ubuntu System

Tight coupling Ubuntu system design of satellite navigation receiver using ARM+FPGA architecture is proposed,Ubuntu sys-tem runs on the ARM,the GPMC interface is used for communication of ARM and FPGA.The design of driving software related to GPMC communication in Ubuntu system is the key point of this paper.First,the GPMC interface principle of ARM Cortex-A8 is intro-duced,and the main driver software module design ideas of the Ubuntu system is given.This design combines the advantages of ARM and FPGA,which increases the speed and stability of the receiver.
