Abstract :
The paper presents new research results of synthesis of compositional microprogram control unit with extended microinstruction format. The method is addressed for programmable logic devices such as CPLD and FPGA and it is oriented on reduction of hardware amount of CMCU addressing circuit. The reduction is reached due to decrease of the number of terms in system of Boolean functions describing the addressing circuit. The research results shows that application of the method for tested GSAs gives on average 50% decrease of hardware amount and 30% decrease of cycle time when compared to CMCU base structure.
