PURPOSE:To set an arbitrary limit range and to reduce the delay time by controlling a selector using an output signal of a memory where an operation result of a computing element is inputted. CONSTITUTION:Inputted two binary numbers A and Bare operated in a computing element 1 and outputted. An output signal E of the computing element 1 is inputted to a memory 2 to designates an address of data stored in a certain address. Each data is stored in a certain address in the memory 2, and the data stored in the address designated by the output signal E of the computing element 1 is read and outputted as an output signal F of the memory 2. A selector 3 selects and outputs one of the signals: the signal E of the operation result outputted from the computing element 1, the first control signal C or the second control signal D, according to the logic of an output signal F of the memory 2. |
