WinCE 下ARM+FPGA 系统

ARM嵌入式单片机和FPGA逻辑电路组成的系统平台是实现仪器仪表便携式、智能化发展的重要方法。系统设计的核心为ARM对FPGA进行管理控制。通过分析ARM的外围总线和与GPIO研究,设计出FPGA通过数据总线交换数据、GPIO完成状态传递的直接连接方式,有效利用了ARM处理器的地址资源,简化了接口电路;通过研究Windows CE系统驱动程序原理和编程,设计了简化的Windows CE对数据总线和GPIO驱动过程,节省了系统资源,完成了ARM+FPG A系统的多通道数据采集系统应用开发。

ARM+FPGA System Based on Windows CE

The embedded platform based on ARM and FPGA of real-time controlling is an important method to intelligent and handy instruments. The kernel of the system design is to manage and control FPGA by ARM processor. The operate principle of data bus and GPIO is analyzed, and then changing data by data bus, changing state for FPGA is designed. The designs simplify the interface circuit. The drivers＇ principle and program technique is researched. The simplification programs of data bus and GPIO are designed to economized system resource. The application multi-data collection system with ARM＋FPGA system is provided.
