介绍了一个基于 DSP,用于采集北京谱仪实验数据的智能模数变换插件的设计方法。此插件是为替代 SL AC于 80年代生产的同类产品而设计的。插件上的 DSP实现了实时数据预处理功能。同时使用了FPGA构造 VME总线接口 ,提高了集成度 A design method of intelligent A / D conversion plug-in based on DSP for collecting experimental data of Beijing spectrometer is introduced. This plug-in is designed to replace the same products that SL AC produced in the 1980s. The DSP on the plug-in implements real-time data preprocessing. At the same time using the FPGA structure VME bus interface, increased integration
