摘　　要：介绍了1种基于FPGA和DSP的高速数据采集系统的设计和实现,其FPGA采用Altera公司ACEX1K系列的EPIK5OTC144_3器件,DSP芯片采用TI公司TMS320系列的TMS320C6713器件.该系统将A/D采样的数据送往FP-GA,经过FPGA预处理后送到DSP,最终通过USB接口送到主控台,其系统的数据采集的实时速度最高可达到100 MB/s,适用于大部分的高速数据采集场合.The design and realization of a high-speed data acquisition system based on FPGA and DSP is introduced in the paper. The FPGA is EPIKSOTC144_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.
