摘要:
Processed results are received when processors make compatible computations on data of a common object. A computation command signal is generated and fed to the processors in response to a start signal from any one of the processors so that the processors can make computations with different operation timings. Then, the results of the computations made by the processors are compared with each other. Thus, apparatus capable of small size, high performance and safety at the same time can be achieved by the above construction using the processors.

An input/output control apparatus including: a unit that controls input/output of data relating to a computation of a plurality of processors in response to an access request from a second input/output unit and an access request from a first input/output unit which requires higher reliability than said second input/output unit, and orders at least one of a plurality of processors to perform a computation relating to the access request from said first input/output unit away from the computation relating to the access request from said second input/output unit in case of that said first input/output unit issued an access request, so that a same computation is made by said plurality of processors; a unit that compares the results of said computations relative to the access request from said first input/output unit provided from said plurality of processors; and a unit that allows the data associated with said computations of said processors to be output on the basis of said compared results.

A self-diagnosis system of a processor capable of realizing a sufficiently high processing ability for control tasks is provided without deteriorating reliability of safety controls even in complex diagnostic techniques. The self-diagnosis system is equipped with a diagnostic target area allocator for allocating a non-active area within a memory as a diagnosis-ready area, which is not used in a control task under execution by a main processor in an independent manner from the main processor; and a diagnostic executor for executing a diagnosis based upon a predetermined sequence in an independent manner from the main processor. In the self-diagnosis system, a diagnostic target area segmented from the diagnosis-ready area is selected, and a diagnosis of the selected diagnostic target area is carried out in each of diagnostic cycles by the diagnostic executor.

A computer system, being a stack bus system in which a plurality of computer modules are stacked and connected to one another and being capable of automatically matching and allocating bus resources such as clocks and interrupts, is provided. In the computer system including one system module and n peripheral modules, each peripheral module includes an interrupt selector, a clock selector, an arbitration signal selector, a resource decision unit, and a position identification unit. The position identification unit cooperates with a position configuration unit present in the system module to identify a position of the module, which includes the position identification unit, in the computer system, and autonomously decides bus resources used by the module. By allowing the interrupt selector, the clock selector, and the arbitration signal selector to select and use the decided bus resources, each peripheral module can match and configure the bus resources in the computer system.

A processing module to use for a processing system having a plurality of processing modules connected via a communication line is comprising mounting position information for the processing module in the communication line; a unique logical address to indicate the processing module; a database to correspond with a physical address of the processing module in the communication line; a position identification device to identify the mounting position information in the communication line of the processing module; a unique/physical address conversion device to fetch the physical address corresponding to the unique logical address from the database using a data packet having the unique logical address as a destination; and a position/physical address conversion device for searching for the physical address from the mounting position information.
摘要:
In a computer system in which a plurality of computers is connected through a network, each computer is allowed to utilize a function of another computer. There are provided policy information and autonomous configuration client for a client computer and server information and autonomous configuration server for a server computer. The policy information has information about a necessary function, a communication system corresponding to the function and application software. The client computer acquires the necessary function from the policy information and retrieves a server computer on the network. The server computer responds to the function that can be provided. The autonomous configuration client exchanges setting information with the autonomous configuration server and autonomously sets the communication system and the application software. The client computer utilizes the necessary function.

摘要:
In a computer system, a device for and a method of conducting self-diagnosis of failure such as a break and a short circuit of a data communication line remove difficulty of conducting the self-diagnosis of the break and the short circuit only by driving and monitoring the data communication line by itself. For this purpose, a diagnosis module receives information necessary for self-diagnosis from a monitoring module connected to the data communication line. The diagnosis module to conduct self-diagnosis is connected via a diagnosis communication line to the monitoring module to communicate diagnosis information between the modules.
