核能谱数据采集 DMA 接口电路

A DMA Interface Circuit for Acquiring Nuclear Spectra Data

利用微机本身具有的ＤＭＡ功能，研制了一种ＤＭＡ方法的核数据快速采集接口，在一个仅５片组件的硬件接口支持下，配置相应软件便可实现核能谱的快速采集。

Based on the DMA function of microcomputer a DMA interface circuit for acquiring fast nuclear spectra data has been developed. The interface circuit, which consistitutes of only five pieces of module and matches with a corresponding software, can realize fast nuclear spectra data acquisition. (
