Abstract

The method of design of compositional microprogram control unit with codes sharing and collections of microoperations is proposed. The proposed method is based on application of special address transformer to form an address of microinstruction on the base of its representation as pair . The control algorithm is described using flow-chart with elementary operational linear chains. Such approach permits to use all positive features of codes sharing independently on characteristics of interpreted flow-chart of algorithm. The proposed method permits to decrease the size of control memory in comparison with all known methods of such control units design. An example of proposed method application is given.

基于EOLC的CMCU设计及微操作集合的编码
提出了一种具有代码共享和微操作集合的组合式微程序控制单元的设计方法。该方法基于特殊的地址转换器,在微指令对表示的基础上形成微指令地址。用具有初等操作线性链的流程图描述了控制算法。这种方法允许将代码共享的所有积极特征独立地应用于算法解释流程图的特征上。与所有已知的控制单元设计方法相比,所提出的方法允许减小控制存储器的大小。最后给出了该方法的应用实例。
