Abstract

PURPOSE:To remarkably simplify the system generation by obtaining individual information of a constitution apparatus at the time of generating a system by setting the information to the constitution apparatus side in advance and reading it out successively from a central processor. CONSTITUTION:When a system generation is started in a central processor 2, the central processor 2 executes read-out with respect to the port sequence (A to F) of a high speed bus 1 by using a prepared instruction in order to obtain apparatus constituting information. Subsequently, based on the constituting information which is read out, the system generation peculiar to each computer system is executed. In such a way, at the time of generating a system, the constituting information can be obtained automatically in the central processor 2 without giving information from the outside, a designation mistake is not generated, and the system generation can be simplified remarkably.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a computer system generation method.

[Conventional technology]

Conventionally, information on the constituent devices of a computer system has been provided from an external source, such as an operator console or external memory, at the time of system generation.

[Problem to be solved by the invention]

The above-mentioned conventional system generation method has a drawback in that the person generating the system must investigate the information of the constituent devices in detail and specify the information without error when generating the system.

[Means to solve the problem]

In the computer system generation method of the present invention, the configuration information of the device is included in the component device side in advance, and the operating environment is set using the configuration information reading mechanism for obtaining the configuration information in the computer main body and the read configuration information. The operating environment can be automatically set without providing information from the outside.

〔Example〕

Next, the present invention will be explained in detail with reference to the drawings.

Referring to FIG. 1, one implementation of the present invention includes a high speed bus 1 with a central processing unit 2. Main memory control device 3. Console control device 4. Online control device5. The disk controller 6 and the magnetic tape controller 7 are connected to boats A and 7, respectively.
Connected by B, C, D, E, and F.

The central processing unit 2 is provided with a configuration information reading mechanism 20, and the other component devices (3 to 8) read configuration information 30 to 80.
have.

FIG. 2 shows main memory configuration information 30 controlled by the main memory control device 3, and FIG. 3 shows disk configuration information 60 controlled by the disk control device 6, which is stored in ROM, deep switch, etc. be done.

The beginning of this configuration information is the device ID (in the example, the main memory is "" o o" and the disk is ".

10”), and the device ID must be uniquely determined within the computer system.
The model number of the connected device and information necessary for the configuration of that device are stored as individual information.

FIG. 4 shows an instruction format for reading out 30 to 80 pieces of configuration information of each device connected to the high-speed bus 1. The operation code (OP) of the instruction and the storage area of the read information (
It has the port number of high-speed bus 1 for reading (capable of register storage) and reading.

Next, the operation of executing system generation will be explained.

When system generation is started in the central processing unit 2,
In order to obtain equipment configuration information, the central processing unit 2 uses the prepared command to read the boat order (A to F) of the high-speed bus 1, and then reads the read configuration information. Based on this, a system specific to each computer system is generated.

〔Effect of the invention〕

As explained above, in the present invention, the individual information of the component devices at the time of system generation is set in advance on the component device side, and the information is sequentially read out from the central processing unit, so that the system can be generated based on that information. , configuration information can be automatically obtained within the central processing unit without providing information from outside during system generation, eliminating specification errors and greatly simplifying system generation.
