Based on FPGA and ARM, one solution is proposed to enhance the accuracy, real-time performance and synchrony in high-speed multichannel data acquisition. The data acquisition system is developed in hardware and software. The modules of data sampling, caching, communication and clock synchronization are designed with the FPGA device of EP4CE115F23C6 as the logic control core in the data acquisition front end. The high-speed acquisition, caching and transmission of data are achieved by the FPGA device. On the basis of WINCE 6.0, the ARM microprocessor of S5PV210 is selected as the upper computer to send the control instructions to the FPGA device. Via the ARM, the parameters can be set and the acquired data can be stored, processed, displayed.Compared with the previous data acquisition solutions, the tests show that the above-mentioned method has the advantages of high precision, high speed, good synchrony, real-time processing and free transmission.
