The most important challenge with the approach of the 21st century is to realize intelligent electronic systems that have instant responsiveness and are superior in such flexible information processing functions as flexible interpretation, approximate judgement, and analogy by intuition. This paper first describes four-terminal devices that substantially increase the functions of the transistor as a baseline device. By using neuron MOS transistors as four-terminal devices, flexware that can instantaneously switch its logical operation function in response to a control signal has been realized. Further, in this paper, a data flow path minimum architecture fundamentally resolving the bottleneck of the present von Neumann computers is described and the MSB-priority bit flow architecture is examined as an advance on von Neumann computers that allows the implementation of approximate judgement in a digital computer paradigm. By using a redundant number system, arithmetic operations, which usually are performed from the lower bits up, and the comparison operations, which usually are performed from the higher bits down, can both be realized by bit flow from the top down. Since the results are put out from the higher-level bits, it is possible to stop lower-level operations whenever a decision is reached. Hence, unnecessary operations can be omitted, and approximate judgment is possible. These original technologies are treated as a basis for the realization of intelligent electronic systems.
