介绍了一种基于ARM9内核的工业级AT91RM9200芯片的嵌入式开发平台设计。重点讨论了硬件设计方案并给出了详细的开发流程。通过采用核心板+扩展板的硬件架构,使用现场可编程逻辑器件扩展系统功能及接口,使得本系统既适合于初学者也适合于项目开发。通过例子使用者可以快速掌握系统架构,并具有建立基于ARM9内核芯片嵌入式系统设计的能力。系统还扩展了GPIB接口便于与通用测试仪器相连。 This paper introduces a kind of embedded development platform design of industrial AT91RM9200 chip based on ARM9 core. Focus on the hardware design and gives a detailed development process. By using the core board + expansion board hardware architecture, the use of field programmable logic devices to expand system functions and interfaces, making the system suitable for both beginners and project developers. By example, users can quickly grasp the system architecture, and has the ability to establish embedded system design based on ARM9 core chip. The system also extends the GPIB interface for easy connection to universal test instruments.
