Abstract

A synthesis method of compositional microprogram control unit on hybrid FPGA (that contain table elements, and programmable logic arrays) is proposed. The main purpose of the method is hardware amount reduction in the control unit circuit. Usage of classes codes of pseudoequivalent operational linear chains for hardware amount reducing in the circuit and overall cost reducing of the control device is proposed. An example of the proposed synthesis method application is given. It is shown that depending on the basis circuit parameters and characteristics of the control algorithm hardware resource saving can reach 30 % in comparison to the costs of basic circuit control device implementation. Time characteristics of control units of modified and base structured are equivalent.
