Szukana fraza: [Abstract = "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."]
