摘要
本文介绍了一种基于PCI总线和DSP处理器的新型脑电信号采集卡的设计与实现。利用ADSP2 1 0 6x卓越的片上处理能力和接口通信能力 ,设计了DSP与A/D转换器间的链路口接口 ,以及与PCI接口芯片间的外总线接口 ,实现了多端口并行数据传输 ,保证了脑电信号采集处理的实时性、高效性。最后给出了具体的性能参数及与国外同类型产品的比较。
This paper introduces the design and realization of a new type EEG&EP Data Acquisition Card based on PCI bus and DSP processor. To fully utilize ADSP2106x's performance, we design a link port interface between A/D converter and DSP, the external bus interface between PCI9080 and DSP. Data transfer can be performed on multiple ports in parallel, and insure the high speed and efficiency of the card. At last, the detailed parameters and the comparison between other Brain Function Analysis system are submitted.
