Abstract

PURPOSE:To obtain a characteristic that could not be secured by an arithemtic system, by connecting plural arithmetic circuits applying different arithemtic systems to a common input and then selecting the arithmetic circuit according to the conditions of the input obtained at a monitor circuit. CONSTITUTION:In the case of two inputs plus three arithmetic circuits, the 1st and 2nd input terminal I1 and I2 are connected in common to an arithmetic circuit P1 of the 1st arithmetic system, an arithmetic circuit P2 of the 2nd arithmetic system, an arithmetic circuit P3 of the 3rd arithmetic system and an input monitor circuit V respectively. The outputs of circuits P1-P3 are connected to an output selecting circuit S. The circuit S is controlled by the output of a circuit V, and either one of these outputs is selected to be sent to an output terminal O.
