摘　　要：设计了一种基于DSP和AD9244的多路数据采集系统,用于采集和处理多路小信号数据。系统采用了高精度高速模数转换器AD9244和DSP芯片,并结合相关的程序和软件,实现了多路数据采集和处理。实验表明,该系统解决了DSP自身模拟转换器精度不高的实际问题。该系统体积小、功耗低,非常适用于对于体积和精度都有很高要求的应用上。Designed a kind 8 roads input small-signal data. combined with related programs show that the system has solved the volume and accuracy having of multi-channel data acquisition system based on DSP and AD9244, used to collect and deal with System used a high precision and high speed analog-digital converter AD9244 and DSP chip, and and software, implementation of the multi-channel data acquisition and processing. Experiments the practical issues of DSP its own converter accuracy is not high. The system is very suitable for very high requirements because the system has small volume, low power consumption.
