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
