摘　　要：研究设计了基于ARM+FPGA的实时数据采集的嵌入式平台,采用FPGA完成高速数据采集,通过ARM对FPGA进行管理控制。解决了测量仪器中高速数据采集与处理速度不匹配的问题以及Linux系统下中断的产生。通过ARM的高级外围总线实现了ARM与FPGA在测量仪器上的接口以及Linux系统下FPGA设备的驱动程序开发。An embedded platform based on ARM and FPGA real-time data acquisition is presented. FPGA is used to complete highspeed data acquisition, through ARM to manage and control of FPGA. The problem of mismatch between the high-speed data acquisition and processing speed is resolved, and the interruption of the Linux system is also provided. The interface of the measuring instruments for ARM and FPGA is implemented through ARM＇ senior external bus, and the driver for FPGA device under Linux system is provided.
