摘要
设计了基于Power PC的嵌入式计算机最小系统,该系统由硬件系统和软件系统组成。硬件系统以P2020为核心,以DDR3和Flash为存储介质,以FPGA为逻辑控制单元,通过Local Bus实现对外总线,通过串口和千兆网实现通信接口;软件系统采用Vx Works6.8操作系统,实现了多核SMP对称多处理架构。功能测试和后期应用表明,该最小系统具有嵌入式计算机运算、控制、通信等基本功能,同时性能稳定,环境适应性强,可扩展性好。
Design a minimum embedded computer system based on PowerPC processor, The System is composed of hardware system and software system. System hardware to p2020 as the core, to DDR3 and flash as the storage me- dium, using FPGA as the logic control unit, by local bus external bus, realize the communication interface through the serial port and Gigabit network; software system adopts VxWorks6.8 operating system, realize the multi core SMP symmetric multi processing architecture. Functional testing and late application show that this system has the basic functions of embedded computer operation, control, communication and other basic functions, at the same time, stable performance, strong adaptability to environment and good expansibility.
