MPC852 And Vxworks-based Embedded System Design

With the rapid development of communications technology, High-speed processor and communications technologies increasingly close integration .The 32-bit embedded processor is in the rapid development in the past 10 years, there are many High-speed communications processor chips on the market, MPC852T ,produced by MOTORALA ,is a high-performance communications controller, the PowerPC core and communications peripherals integrated in one, with multiple support a variety of peripheral interfaces, communication protocols, therefore, the processor chips, especially for communications, such as communications base station.Wind River System is a company which specializes in embedded real-time operating system, software development , in real-time operating system field, Wind River System is the most internationally recognized company with a leadership role. Wind River System's VxWorks is the launch of a real-time operating system,and is a high performance, reducable embedded real-time operating system. Because of its excellent reliability and excellent real-time performance,VxWorks has been widely used in communications, , aviation, aerospace and other sophisticated technology and real-time demanding areas.Embedded processor and embedded operating systems are respectively the cores of embedded systems, hardware platforms and software platform. Because of the different target applications, hardware platforms vary, generally the operating system can not directly run on the hardware platform up ,which involves the operating system transplant, that is, BSP and driver software development.In this paper, in order to test a chip used in communication base stations, design and development of a complete set of embedded hardware and software system. Consist of MPC852T processor minimum system design, operating system migration (ie, BSP and driver software development), the upper application software design.
