基于龙芯2F的便携机主板设计技术研究与实现

摘要

Design computer mainboard based on Loongson 2F, and implement power clock and reset circuit, and how to extened periphery interface based on PCI bus interface. The mainboard use VxWorks as its embeded OS. The mainboard has been in product applications, and performs stable.%基于龙芯2F处理器设计紧凑型便携机主板,基于处理器内部集成的PCI总线接口扩展显示、USB2.0、IDE、千兆网络等多种外围接口,突破系统电源设计、中断路由实现等关键技术,运行VxWorks操作系统,已经应用于项目,运行稳定可靠.
