Network Communication Platform Based On The PowerPC And Vxworks

In recent years, With embedded system application is more and more widely, the communications industry has experienced rapid change, Depending on the specific application, Network communication devices toward more miniaturization, low power consumption, high transmission rate in the direction of development.In this paper, For an individual with communications equipment unit as the application background, With the application fields of equipment miniaturization, low power consumption and high performance requirements, We have designed a kind of low power consumption, high transmission rate, high stability of the network communication platform, Using communication processor MPC8548 chip and embedded real-time operating system.This paper analyzes the network communication platform of the overall plan and design process, also discussed the project demonstration and chip embedded communication platform, choice of system, and completed the communication platform of the overall design of hardware circuit and the principle diagram and PCB diagram drawing, In addition, introduced the DDR2 memory extension and implementation of gigabit Ethernet front-end ports, In the end, On the basis of BSP file modifications, On the premise of generating system image, finally achieved the transplantation of the operating system.Interface to extend through the platform, we can develop small high-speed communication terminal also can develop the protocol conversion equipment and individual bearing equipment, etc.
