A general neuro-computer and system using it is capable of executing a plurality of learning algorithms, providing an instruction execution speed comparable with a hard wired system, and practically neglecting a time required for rewriting microprograms. The neuro-computer is constituted by a neuron array having a plurality of neurons, a control storage unit for storing microinstructions, a parameter register, a control logic, and a global memory. A host computer as a user interface inputs information necessary for the learning and execution of the neuro-computer to the system, the information including learning algorithms, neural network architecture, the number of learnings, the number of input patterns, input signals, and desired signals. The information inputted from the host computer is transferred via a SCSI to the neuro-computer to perform a desired neural network operation.

Neuro-computer system for executing a plurality of controlling algorithms

An information life cycle management system and an information organizing method using the computer system stores information objects composed of a database and program, and a data processing device for processing an information object which is a block of the information in the storage device. Processing and execution of an information object is managed based on information life cycle states, starting with generation of the information object and ending with aborting the information object. An information accessor manager governs the available operation type and area of use of manager information based on the information life cycle state. As information object definition language defines attributes of the information structure and information life cycle state and the managed information object. The information objection is managed in accordance with contents defined by the language. An administrator of the information object with an information life cycle transform language controls the transform sequence and timing of the information life cycle state transformation for each information object. A transform of the information life cycle state is controlled in accordance with the contents defined the language. An information access unit provides an access language for using the information object and selecting and executing a proper access method based on the information life cycle state of the information object. Thus, the information is processed safely and efficiently based on the information life cycle state starting with the generation state and ending with the abort state of the information object.

Information life cycle processor and information organizing method using

An object-oriented data base management system connected to a plurality of data bases includes a class definition unit, a static inheritance processing unit included within the class definition unit, a message processing unit, a dynamic inheritance processing unit included within the message processing unit, and an object management unit. The object-oriented data base management system is of the type that defines the inheritance relationship between a plurality of classes and an arbitrary class and the inheritance priority order, the class being a basic unit of programming, and executes the data processing by solving the inheritance relationship between classes in accordance with the priority order. There is prepared, for each class, updatable inheritance solution status information which the static inheritance processing unit causes to be stored in a table. The inheritance solution status information includes status information and time information. The status information is representative of whether or not inheritance between the class and the superclasses can be completely solved, and the time information is representative of a time when the status is established. When a message processing is requested for an object of a class, the dynamic inheritance processing unit searches the method designated by the message while referring to the inheritance solution status information regarding the class and the superclass stored in the table.
