Abstract: The design and realization of a high-speed data acquisition system based on FPGA and DSP is introduced in the paper.The FPGA is EPIK5OTC144_3 which belongs to ACEX 1K serial and produced by Altera;while the DSP processor is TMS320C6713 which belongs to TMS320 serial produced by TI.The data acquired by ADC is transferred to FPGA,then transferred to DSP after being pre-processed by FPGA and finally to console via the interface of USB.The system’s real-time data acquisition rate is up to 100MBYTE/S,so it is applicable to most of the high-speed data acquisition occasions.

Key words: high-speed data acquisition, FPGA, DSP, AD9446
