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 controlunits design. An example of proposed method application is given.

Two methods are proposed targeted at reduction in the number of look-up table elements in logic circuits of compositional microprogram control units (CMCUs) with code sharing. The methods assume the application of field-programmable gate arrays for the implementation of the combinational part of the CMCU, whereas embedded-memory blocks are used for implementation of its control memory. Both methods are based on the existence of classes of pseudoequivalent operational linear chains in a microprogram to be implemented. Conditions for the application of the proposed methods and examples of design are shown. Results of conducted experiments are given.
