微控DMA原理及其在测控领域的应用

MICROPROGRAMMING-CONTROLLED DIRECT MEMORY ACCESS AND ITS APPLICATION IN THE FIELD OF TEST,MEASUREMENT AND CONTROL

提出了一种基于微编程的新型ＤＭＡ方式──微控ＤＭＡ（ｍｉｃｒｏｐｒｏｇｒａｍｍｉｎｇ－ＣｏｎｔｒｏｌｌｅｄＤＭＡ）及以此为核心，借助于大容量存储区提供的系统紧耦合能力，建构通用多功能微机数据系统的原理，并探讨了该实际系统在测量、测试、控制及微机数据网络等领域的广泛应用前景。

new Direct Memory Access(DMA)based on microprogramming,Microprogram-ming-Controlled Direct Memory Access(MCDMA)is presented,and the constructional mecha-nism of a universal microcomputer data system depending on MCDMA and tight-coupling structure of bulk memory is proposed.In the end,the wide application of this system in the field of test,measurement,control and microcomputer data network is approached.
