PURPOSE:To obtain the single point system enabling the high speed of fuzzy inference by converting the duration of phenomena indicating the prescribed logic state into a physical value according to the length of time and outputting the averaged physical value after averaged while reallocating the physical value converted for each element. CONSTITUTION:A fuzzy inference engine which is the basic circuit for fuzzy calculation constitutes a minimum value selection circuit with an AND gate Ga, the maximum value selection circuit with an OR gate Go, determines the maximum value in the minimum value of the value for each element with sets A and A' to obtain a conclusion B' by performing the head off by an AND gate Gm. In this case, the dimension of a membership function is expressed by the duration for the phenomena indicating the logic state such as the pulse, this duration is converted into the physical value like the amount of an electric charge, the physical value converted for each element is reallocated to be averaged, the reallocated physical value is finally converted into voltage to be outputted. Thus, the single point processing to obtain the conclusion in the fuzzy calculation can be speeded up. |
