摘要
介绍了以Freescale公司的高性能嵌入式芯片MPC5200B为处理器的嵌入式系统的设计,设计了外部存储器、通信接口部分、显示控制部分等,并对其系统软件VxWorks的BSP进行了配置。MPC5200B集成有高性能的MPC603e内核和丰富的外设接口,提高了MPC5200B的处理能力,可为大多数视频处理算法提供足够的支持。最后对系统进行了验证,系统很好地满足了嵌入式视频信号处理系统的要求。
The paper introduces the embedded controller chip MPC5200B with MPC603e kernel of Freescale,and describes the system design of video processor based on MPC5200B. The structure and function of system are discussed in detail. And the BSP of the system is configured. In the system,external memory,communication interface and the display controller are designed. The MPC5200B integrates a high performance MPC603e core and plentiful peripheral interface which can improve the processor ability of MPC5200B. So it supports most of the video process arithmetic.
