摘要
该文介绍了串口通信标准,提出了基于NIOS II嵌入式软核处理器的串口通信设计方案,重点研究基于NIOS II的串口电路的硬件设计过程,阐述了在NIOS II集成开发环境下串口通信的软件实现过程。基于NIOS II的串口通信可应用于导航解算系统,实现导航解算芯片的数据库加载。
This paper introduces the standard of UART communication, and puts forward the scheme of UART communication which based on the NiosⅡ embedded softcore processor, then emphasizes on studying the hardware design process of UART. Under the Nios Ⅱintegration development environment , it expatiates the process of software implement for UART communication . The UART communication based on the NiosⅡ processor can apply in the navigation solution system , achieve to load the database to the navigation solution chip.
