Композиционные микропрограммные устройства управления с максимальным кодированием микрокоманд

Abstract

Barcalov A.A., Strunilin V.N. The composition microprogram control units with maximum coding of microcommands. The microprogram control units ( МCU ) find wide application at realization of various digital systems [ 1 ]. The composition microprogram control units ( CМCU ) are one of classes of similar devices [2,3 ]. In this work there are proposed methods, enabling to optimize hardware costs in CMCU by use of maximum coding of microcommands. There are proposed of two- and three-level structures CMCU with maximum coding of microcommands on programming logic arrays ( PLА ) and read-only memory devices ( ROM ). Algorithms of synthesis of offered structures CMCU are indicated. The optimal coding algorithm of microcommands set is described with a minimum length of a coding word
