Synthesis of Control Unit with Modified Microinstructions

Abstract

The method of optimization of the hardware amount in addressing circuit of compositional microprogram control unit is proposed. Method is based on expansion of the microinstruction format by the field with code of the class of pseudoequivalent operational linear chains. Minimization is reached due to decrease of the number of terms in system of Boolean functions describing the addressing circuit. An example of application of proposed method is shown.
