On the basis of embedded system and data acquisition technology a practical and new intelligent controller is studied, designed and implemented for the high-speed and real-time data acquisition applications, which is based on ARM＋FPGA architecture.This paper describes the implementation of some hardware technologies such as of the minimum system of host processor ARM, the minimum system of coprocessor FPGA and the communication interface of ARM and FPGA, as well as the development of the driver of the Linux character device of FPGA, the control program of coprocessor FPGA and the application design of main processor ARM. The intelligent controller takes the advantages of the parallel computing processing structure of FPGA to control the ADC carrying out high-speed data acquisition. FPGA can be configured into a soft-core processor-Nios II embedded processor, constituting a dual-core processor system with ARM. The intelligent controller implement the management and control of FPGA, the real-time data acquisition, and the rich peripheral interface communications through ARM.
