介绍了一种新的基于NIOSII的导航系统的设计方案.NIOS是建立在FPGA上的嵌入式微处理器软核,由于它硬件设计上的灵活性和可裁减性,使得软件设计上“平台”的概念延伸到硬件设计中。本文就是把NIOSII硬件平台的方案,在导航系统计算机设计上进行了有益尝试,实践证明,本设计不但实现了预期功能,而且为以后在其他导航产品上快速的移植硬件和软件系统,提供了有力保证。
This paper introduces a new design scheme of NIOSII-based navigation system.NIOS is an embedded microprocessor soft core built on FPGA. Because of its hardware design flexibility and cuttability, "The concept extends to the hardware design. This article is the NIOSII hardware platform for the navigation system computer designed to make a useful attempt, the practice has proved that this design not only to achieve the desired function, but also for other navigation products in the future rapid porting of hardware and software systems, provides a powerful Guarantee.
