摘要

提出了一种代码共享的组合式微程序控制单元的设计方法。该方法利用专用地址转换器将微指令地址表示为操作线性链的对码、元件码，从而形成微指令地址。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

Optimization Of Control Memory Size Of Control Unit With Codes Sharing

The method of design of compositional microprogram control unit with codes sharing 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 code of operational linear chain, code of components. 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
