介紹了一種新的基于NIOS II的導(dǎo)航系統(tǒng)的設(shè)計方案. NIOS是建立在FPGA 上的嵌入式微處理器軟核, 由于它硬件設(shè)計上的靈活性和可裁減性，使得軟件設(shè)計上“平臺”的概念延伸到硬件設(shè)計中。本文就是把NIOS II硬件平臺的方案，在導(dǎo)航系統(tǒng)計算機設(shè)計上進行了有益嘗試，實踐證明，本設(shè)計不但實現(xiàn)了預(yù)期功能，而且為以后在其他導(dǎo)航產(chǎn)品上快速的移植硬件和軟件系統(tǒng)，提供了有力保證。

Abstract: This paper introduces a new design scheme for the navigation system platform based on NIOS II. NIOS is an imbedded micro-processor’s soft core based on FPGA . Because of the flexibility of the hardware’s design, we can popularize the conception of“platform” from the software’s design to the hardware’s. It is proved that this design works well, and it assures that the hardware and software system could be fast replanted to other navigation products.
