PROBLEM TO BE SOLVED: To prevent enlargement of a wiring area, when the number of computing elements of a processor is increased, and improve operation stability and performance of the processor by reducing crosstalks. SOLUTION: Arrangement is performed in the relation where a main propagating direction of an operand data signal in a register file circuit 10 (generally, the direction coincides with the direction of a bit line for constituting a resistor file) and the main propagating direction of data signal, in the course of operation processing in fixed-point computing element circuits 20, 21 and floating-pint computing element circuits 30, 31 intersect orthogonally with each other. All of the computing element circuits 20, 21, 30 and 31 are arranged on one straight line, in such a manner that bit slice pitches are made identical and bit positions coincide with each other. A wiring for transmitting an inputted operand data signal and a wiring for transmitting an outputted operand data signal are made to be arranged alternately, and crosstalk is reduced.
