龙芯2F处理器在工控嵌入式系统中的应用

介绍了一款采用我国自行研发、具有自主产权的通用微处理器芯片——龙芯2F为处理核心的嵌入式系统设计,该系统根据工控嵌入式系统的需求特点,采用AMD GeodeTMCS5536作为系统的南桥,设计了相应的驱动电路和接口。系统板面积为140 mm×100 mm,板载FLASH和DDR2内存,硬盘、CF卡、USB、鼠标、键盘等接口,利用串、并口为系统终端。该系统具备普通PC机的所有接口,故也可作为普通PC机主板使用。

Loongson-2F processor application in industrial embedded system

This paper introduced a design of embedded system that used a general-purpose microprocessor chip,loongson-2F CPU,as its processing core.The loongson-2F CPU was designed in China and has independent intellectual property rights.The system used the driving circuit and interfaces based on the characteristics of the embedded industry controlling system and used the AMD GeodeTMCS5536 as its south bridge.The motherboard was 140 mm×100 mm in area and contained a series of interfaces,such as FLASH,DDR2 memory,hard disc,CF card,USB,mouse,keyboard etc.The system used the serial and parallel port as its terminals and can be applied to the general PC Motherboard.
