摘要
本文介绍了两种方法将外设接入Avalon总线,以构建基于NiosII嵌入式处理器的SOPC的方法,分别是通过自定制接口直接接入总线和以通用I/O口的方式接入总线,并编写了可供用户直接调用的相关程序。两种方法均在Altera的cycloneII系列器件上进行了验证,试验结果正确。
This paper introduces two methods of connecting a peripheral component to Avalon bus to construct a sopc design based on NiosII embedded processor, which are connecting to the Avalon bus directly and connecting through general I/O. It also provides re-lated software programs for users. The two methods are proved by experiment on cyclonII device from Altera Company, and also the result turns out to be good.
