摘要:
A replicated data processing method and apparatus for a distributed processing system are provided in which a plurality of processors are connected to one another through a common transmission line. The processors perform processes using replicated data produced by resources such as files replicated in respective processors. Any processor issues an access request and broadcasts the request to the common transmission line. User's program of the processor is initiated by a first-received data in response to the request, and checks matching between the first-received data of the replicated data and the subsequently received data to repeat a retry processing for the request until a mismatch is removed.

A data management method in a distributed processing system having a plurality of processors connected through a common transmission line with at least one processor having at least one external device connected therewith, for sending to the common transmission line access commands issued to the external device by programs asynchronously executed in the programs as access messages; and wherein the processor having the external device connected therewith takes in any of the access messages related to the external device connected therewith from among the access messages asynchronously sent to the common transmission line by the programs, and the processor matches order of access to the external devices connected therewith among the received access messages.

A resource management method and system for version-up in a multiprocessor system having functions that a processor to be made version-up investigates resources under control by the own processor itself before deciding if any of the resources are to be moved and/or duplicated, that the processor can decide the processors to which the movement and/or duplication of any of the resources is destined, that the resource is moved or duplicated to the destined processor. After that, version-up of the processor to be made version up is executed, thereby effectively using the resources and making version-up while the multiprocessor system is under operation.

In a multi-computer system in which a plurality of computers connected to each other through a transmission medium share a process to be carried out under relationships among a method performed by these computers executing a control instruction, characterized as; while the plurality of computers each have specific control instruction storage means for storing instructions having influence on normal operations of the multi-computer system, when any of the plurality of computers defects an input instruction corresponding to one stored in the specific control instruction storage means, determines the status of the shared process being carried out by other computers in connections to the self-computer, and uses the result of the determination in the execution of the detected control instruction.

A loosely coupled multiprocessor computer includes an input/output control unit for fetching both a program and data derived from an external input device and also for outputting processed data to an external output device; storage for storing therein both the program and data inputted from said input/output control unit; process unit for sequentially executing a processing operation of the data based upon the program stored in the storage; and, a transmission medium for coupling the process unit, input/output control unit and storage with each other. In the loosely coupled multiprocessor computer, a serial transmission medium is employed as the transmission medium. A transmission control unit for performing both a conversion process between data to be transmitted, flowing through the serial transmission medium and the processed data, and also a transmission/reception process of the data to be transmitted via the serial transmission medium, is provided with the input/output control unit, storage and process unit. A unit process unit for controlling the input/output control unit, storage, and transmission control unit is provided with the input/output control unit and storage with the transmission control unit.

A method for executing programs in a distributed processing system includes executing in a plurality of first processors different programs which perform the same function. Messages, containing data representing execution result output from said different programs and attribute information indicating function to be performed by the different programs, are transmitted from the first processors to a network. A second processor then receives these messages and selects a message therefrom based on an analysis of the attribute information contained in all of the received messages. The second processor then executes an application program using the data contained in the selected message. Alternatively, the message-selecting step is made based on both the attribute information and data contained in the messages received in the second processor. Each of the messages from the first processors may include graphic image data which can be analyzed and shown on a display.

A data processing system for inputting data to a form display includes a scanner for inputting an image of a form document to the system, a processor for recognizing character and line patterns from the form document image supplied from the scanner to produce physical structure data of the document and logical structure data related to data input/output fields in the form document depending on the physical structure data so as to automatically produce based on the logical structure data a program to input data to the form display, a display screen for presenting thereon a form display defined by the physical structure data or normalized data obtained by correcting the physical structure data to be adaptive to a cursor pitch, a data input key apparatus, and a printer for producing a printout document based on the form display filled with the data.
摘要:
Method and system for dispensing a document form including input/output fields into which a character train or a numerical value data train is written on a screen such that the operator can easily correct it on the screen or by a format such that data can be easily input/output into/from the input/output fields thereof for processing. describing a format of the document is read out of a recording medium in which the document format has been written, the read data is displayed on the screen with a format which is the same as or similar to the format written on the recording medium. When the document form is displayed on the screen a character size per character displayed is decided from the read data, the cell is arranged on the basis of the decided character size, extra-cell data such as character or numerical value data or the like is arranged on the basis of the arranged cell, the cell and the extra-cell data are compressed so as not to overflow the display screen, and a processing procedure of items of the format displayed in the display screen is determined.
摘要:
A character data input method for an information processing system. Image information on a form which has only a format and on which no data is recorded is read from an input unit for inputting image information. A plurality of input areas in which data is recorded is prescribed by utilizing this image information. Image information on the same form on which data is recorded is thereafter read from the input unit. The format and data are discriminated from image information on the form on which data is recorded based on the recognized character pattern and border pattern of the format and the information prescribing the data input areas to recognize a character pattern in each data input area.
