摘　　要：介绍了一种基于DSP的高速数据采集与处理系统方案,给出了方案构成的硬件系统平台设计,并详细阐述了各硬件系统平台的具体构成。对采集后的数字信号的后续处理做了简要介绍,并给出了数字下变频模块的具体实现,利用嵌入式逻辑分析仪测试了并验证了AD采样信号的正确性。该数据采集与处理系统具有一定的通用性和可扩展性,具有一定的工程应用价值。A scheme of the high speed data acquisition and processing system based on DSP is introduced in the paper. The design of hardware system is proposed and the composition is described in detail. The processing of the latter digital signal acquisited is briefly introduced and the realization of digital down conversion is given.The sampling signal is tested and verified correctly though embedded logic analyzer. The data acquisition and processing system has some universality and expansibility and application value in project.
