Abstract

PURPOSE:To eliminate errors at the time of the replacement of a module and to facilitate module control by providing a read-only circuit for each replacement unit of an information processor and writing information which is required during the replacement in the circuit. CONSTITUTION:The replacing module 41 consists of a processor body 51, the writable read-only memory circuit 61 where information on features of the processor body 51 is written, a readout control circuit 62, and a switching circuit 63. A module number and a replacement indication symbol as the information written in the read-only memory circuit 61 are effectively used to check an error during replacement and a manufacture lot number is usable as replacement history information on the device. Further, performance information is utilized as memory capacity per module, memory cycle time information, etc., when the replacing module is a memory device, and used as information for system reconstitution such as arithmetic processing time when the module is an arithmetic unit.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a replacement module management system used in an information processing device.

[Conventional technology 1 Conventionally, this type of replacement module has displayed the module name, module number, 1-minimal number, symbol indicating compatibility, and manufacturing lot number by a visual display method such as stamping inside the module. .

[Problems to be Solved by the Invention] 1 The above-mentioned conventional replacement module management method uses a visual judgment method such as stamps or etched characters, so there is a risk of misreading the display contents or misreading the display information. Due to the small size, there were drawbacks such as misjudgment of compatibility. In addition, there are many drawbacks such as the inability to immediately respond to management by manufacturing loft and provision of information on exchange history, the management method becomes complicated if replacement modules are classified by performance, and modules with inclusive compatibility In many cases, it takes time to investigate and confirm the exchange, which was also a drawback.

An object of the present invention is to provide a dedicated reading circuit for each replacement unit of an information processing device, and to write detailed information necessary at the time of replacement into the readout circuit. An object of the present invention is to provide an easily exchanged module management system.

Means for Solving Problem 1 J The exchange module management system of the present invention does not indicate the characteristics of each exchange module in a plurality of devices constituting an information processing device, and , a rewritable read-only memory circuit into which history information or performance information is written, and a circuit that reads the output of this read-only memory circuit.
1. A system t that manages a system configuration within the information processing device by successive outputs from each of the memory circuits.
It is characterized by comprising a 1.1 configuration management device.

l Fruitful village r Shiri -1 Next, the present invention will be explained with reference to the drawings.

FIG. 1 shows a block M of an information processing apparatus including an embodiment of the present invention. Inside the information processing device 1 is the system control device 1
Each device (
(including system control device and system configuration management device) are constructed in module units, each of which can be replaced.
In some cases, each device consists of multiple modules, each of which serves as a replacement unit.

FIG. 2 is a block diagram showing the internal configuration of the exchange module shown in FIG. It is composed of a read control circuit 62 that controls the output of the read-only memory circuit 61 and sends it to the switching circuit 63, and a switching circuit 63 that switches information between the processing device main body 51 and the continuous read-only memory circuit 61.

The information written to the read-only memory circuit 61 includes the module number, compatibility designation symbol, manufacturing lot symbol, performance information, etc. The module number and compatibility designation symbol are effective for checking errors during replacement, and the manufacturing lot symbol. can be used as device replacement history information.

In addition, performance information can be used, for example, if the replacement module is a memory device, such as the memory capacity per module and memory cycle time information, and if it is a processing unit, it can be used as information for system reconfiguration, such as calculation processing time information. .

〔Effect of the invention〕

As explained above, the present invention adds a rewritable read-only memory circuit containing -X information indicating its characteristics to each replaceable module of an information processing control device, and by reading this, the module can be replaced. This has the effect of eliminating time errors, automatically reconfiguring the system from the performance information of the replacement module, and facilitating the management of replacement bTj history information.
