Abstract

PURPOSE:To reduce generation manhours at the time of developing a program and maintenance manhours after development with only one file for a whole system by selecting a corresponding function module-only table in accordance with an identification value showing a function module so as to obtain a device access address concerned. CONSTITUTION:Processors Pa and Pb are connected by an inter-processor bus Ba and the processor Pa and respective devices Da-Db are connected by an intra-processor bus Bb1 via a common bus interface device B1. The processor PB and respective devices Dc-Dd are connected by an intra-processor bus Bb2 via the common bus interface device B1. The respective processors Pa and Pb transmit a request signal for reading a function module type to the common bus interface device B1 by an initialization processing at start time and obtains the identification value showing the function module by the response signal. The device access addresses of the respective devices in the processors are extracted by using the function module identification value.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a processor function type identification system for identifying the function type in a function share type system in which the system is composed of multiprocessors and each processor is divided into a plurality of functions.

[0002]

2. Description of the Related Art Conventionally, in this type of identification, a file called a load module (hereinafter referred to as LM) is separately created for each functional unit, and the identification value indicating the function is changed in the contents of the station data in the file. Was identified by.

[0003]

In the conventional method, the LM
The number of created files is the same as the number of function types, which not only increases the work man-hours when developing a program, but also requires the file version number management according to the number of LM types when performing maintenance after development. This is also a factor that increases man-hours.

[0004]

According to the processor function type-based method of the present invention, in a system composed of function-divided multiprocessors, each of the multiprocessors is started by its own processor. In the initial setting process, the request signal for reading the functional module type is transmitted to the common bus interface connecting the processor and each device, and the identification value indicating the functional module is obtained by the response signal to the request signal. Yes, according to the identification value indicating the functional module, select the table dedicated to the corresponding functional module,
The configuration is such that the corresponding device access address is obtained.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1a is a block diagram of a central office switch composed of a multiprocessor for explaining an embodiment of the present invention. The processors Pa and Pb are connected by an inter-processor bus Ba, and the processor Pa and each device (for example, general-purpose IO device, dedicated SP system device) Da to Db are connected to the in-processor bus Bb via the common bus interface device BI.
1 is connected. Similarly, in the processor Pb, the devices Dc to Dd are also connected by the in-processor bus Bb2 via the common bus interface device BI.

Paying attention to the fact that each device is different for each functional module, the processor Pa, Pb has a function capable of reading a value for identifying the functional module from each device by a reading method common to all the functional modules. Build a new one.

FIG. 1B is a sequence diagram of signals for reading the functional module identification value between the processor and the common bus interface in the processor in FIG. Each of the processors Pa and Pb sends a request signal for reading the functional module type to the common bus interface device BI in the initialization process when the processor itself starts to start, and an identification value X indicating the functional module is sent by the response signal.
To get

FIG. 2 is a diagram showing an embodiment of station data in which all functional modules are integrated. The functional module identification value X obtained in FIG. 1B is used to access the device access address of each device in the processor. To extract. For example, both the device Da and the device Dc in FIG. 1A are magnetic tape (MT) devices, but the device access address in the processor Pa is I.
It is used when OA1 and processor Pb need to be accessed with different values such as IOA3.

In the MT device access program, when the MT device is accessed, the head table is indexed by the identification value X, the child table dedicated to the own function module is selected, and the device name value indicating the MT device is selected in the selected table. By indexing with IOA1 for processor Pa,
When the processor is Pb, IOA3 can be obtained.

[0011]

As described above, according to the present invention, it is not necessary to separately create a load module file for each function unit, and only one file is required for the entire system. This has the effect of reducing maintenance man-hours after development.
