基于NIOS II的導(dǎo)航系統(tǒng)平臺(tái)的設(shè)計(jì)

介紹了一種新的基于NIOS II的導(dǎo)航系統(tǒng)的設(shè)計(jì)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(jì)上的靈活性和可裁減性，使得軟件設(shè)計(jì)上“平臺(tái)”的概念延伸到硬件設(shè)計(jì)中。本文就是把NIOS II硬件平臺(tái)的方案，在導(dǎo)航系統(tǒng)計(jì)算機(jī)設(shè)計(jì)上進(jìn)行了有益嘗試，實(shí)踐證明，本設(shè)計(jì)不但實(shí)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.
