PURPOSE: To provide a neural network using a digital architecture.

CONSTITUTION: A method is to transfer a signal among plural digital processing elements. A stage for storing plural digital signals and providing one of the plural digital signals to an output bus 28 in accordance with an address signal and a stage for increasing the address signals and energizing control signals at the time of increasing the address signals are provided. Furthermore, a stage for transferring the output signals of the plural digital processing elements to continuous routes through plural electrically separated conductors 30 in response to the control signals so that the output signals of the plural digital processing elements are synchronized with the prescribed signals of the plural digital signals for a processing in the plural digital processing elements 14-24 is provided.
