In the article two methods of designing of CMCU are proposed. Both methods are oriented on application in the system-on-a-chip where dedicated memories can be used for implementation of control memory of CMCU. First method is based on the CMCU with base structure that was previously used only to the programmable devices (PLD). In the article some required changes in the structure of CMCU in order to use System-On-Chip devices (SoC) with built-in memories were proposed. Second method is based on using of part of the address of microinstruction as a code of the output o operational linear chain (OLC). The results of research of effectiveness of both methods are shown. The researches conducted by authors base shown that the best under the characteristics of interpreted flow-chart method of CMCU permits to decrease an amount of logic-elements in comparison with CMCU with base structure up to 35+42%.
