基于SOPC的数据采集显示系统的设计方法

Design Method of Data Gathering and Displaying System Based on SOPC

本论文介绍了一种新型的基于NiosII的SOPC数据采集显示系统的设计方法。该设计有效的解决了单片机领域中速度较慢的CPU和高速的A/D转换器之间的速度匹配问题。另外,利用DMA直接内存存取的数据传输技术,提高了体统的性能,解放了CPU,解决了大量数据高速采集与显示的问题。本系统SOPC芯片采用的是ALTERA公司的EP3C5E144,该系统以SOPC为核心,体现了SOPC系统集成度高、灵活性强的特点,并缩短了产品的开发周期。

One of design method of SOPC data gathering and displaying system based on NiosII is introduced in this paper.It effectively solves problem in cooperation between high speed AD conversion and lower CPU on the SCM.By using this direct memory access transfer technology improved the system characters,enhanced CPU efficiency,solved the problem of data gathering and displaying.EP3C5E144 of Altera is chosen as SOPC of this system.SOPC is the core of the system,showing high integration,flexibility,expandability of SOPC and reduction of the time of development of product.
