JPS63182768A - Identifying system for rising method of processor - Google Patents

Abstract

PURPOSE:To realize the automatic identification of the rising method of each processor and to improve the operability with processors, by adding a constitution information storing device to those processors. CONSTITUTION:The processors 20-2n reads the processor constitution information out of a constitution information storing device 1 in the rising state of each processor. If the processor constitution information is kept in an initial state, it is regarded that all processors rise simultaneously and a normal operation is carried out. If the processor constitution information is not kept under an initial state, a set-in rising operation is carried out with its own processor cut off and a normal rising operation is carried out with its own processor kept under an operation state with reference to a part of its own processor corresponding to identifiers C0-Cn in an operation state column (d). A master processor 20 cuts off a processor having no rise and produces the processor constitution information to write it into the device 1. Thus it is possible to automatically identify the rising way of each processor with no intervention of manual operations.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for identifying a startup method for a processor, and more particularly to a method for identifying a startup method for a processor in a loosely coupled multiprocessor system.

[Conventional technology]

Conventionally, when starting up a loosely coupled multi-processor system, it was necessary to set the startup mode switch before startup, or to obtain instructions on how to start up from the console during startup. .

[Problem that the invention seeks to solve]

The above-mentioned conventional techniques require manual intervention and have poor operability. There was a problem in that the i-system did not start up or some processors were disconnected due to an error in specifying the startup method.

SUMMARY OF THE INVENTION In order to solve these problems of the conventional technology, it is an object of the present invention to provide a method for automatically identifying the startup method of each processor without requiring manual intervention.

[Means for solving problems]

According to the present invention, in a loosely coupled multiprocessor system having a mask processor that monitors the operational status of other processors, each processor is connected to a configuration information storage device, and means for writing processor configuration information from the mask processor to the configuration information storage device. and means for reading processor and configuration information from the configuration information storage device to each processor.

At startup, each processor reads the processor configuration information from the configuration information storage device, and depending on the contents of the processor configuration information, determines whether the startup of its own processor is a normal startup or an embedded startup. A processor startup method identification method is obtained, which is characterized in that processor configuration information is written into the configuration information storage device after startup and when the processor configuration is changed.

〔Example〕 Next, nine aspects of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of an apparatus to which the present invention is applied. In the figure, 1 is a configuration information storage device, and 10 is a loosely coupled multiprocessor system. This loosely coupled multi! 20 to 20n in the processor system lo are processors, of which the master processor 20 is the processor 2.
Monitor the operational status of 1 to 2n.
1. Each of the processors 20 to 2n is connected to the configuration information storage device 1.

FIG. 2 is an example of processor configuration information in the configuration information storage device l. In the figure, co % cn indicates the configuration of the processor processors 20 to 2n, in order to check whether the startup of the own processor is a normal startup in which all processors are started at the same time, or an embedded startup when other processors are in operation. Read processor configuration information from the information storage device 1.

If the processor configuration information is in the initial state, it is assumed that all the processors will be started up at the same time, and normal startup will be performed. If the processor configuration information is not in the initial state, refer to the part corresponding to the identifier of the own processor in the operation status d column, and if the own processor is disconnected, start up the built-in process, or if the own processor is in operation, start up normally. Do a raise.

After a normal startup in which all processors are started up simultaneously, the master processor 20 creates processor configuration information by placing the processors that have started up in operation, disconnects the processors that have not started up, and writes them into the configuration information storage device 1.

In addition, when a certain processor goes down and is disconnected, or a certain processor is installed and the configuration state changes, the master processor 20 creates processor configuration information based on it and stores it in the configuration information storage device 1. Write.

When instructed by the processors 20 to 2n, the configuration information storage device 1 sends the processor configuration information to the processor that gave the instruction. Further, the configuration information storage device 1 is a master processor 20
When processor configuration information is received from , the previously saved processor configuration information is replaced with new processor configuration information, and the latest processor configuration information is always saved.

〔Effect of the invention〕

As explained above, the present invention has the effect of automatically identifying how to start up each processor in a loosely coupled multiprocessor system without requiring manual intervention.
