Design of an ARM9-based embedded industrial personal computer system

A design method of slot-embedded industrial personal computer (IPC) system based on ARM9 is presented in this paper. This method includes the design of hardware structure and software management platform of the IPC system. The hardware structure, which includes PCI communication module, man-machine interface module, Ethernet communication module and CAN bus communication module, is addressed in detail. The Linux operating system is employed as the software management platform, and a dual-core structure is used to study its real-time performance. The proposed system has the merit of low cost, strong versatility, stable and friendly interface. It will be widely used in the field of industrial control.
