Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention is applied to a main frame link communication means of a microcomputer. In particular, the present invention relates to a micro mainframe link communication means when a process executed on a microcomputer operation system connected to a host computer system performs distributed processing with a process executed on the host computer system.

〔overview〕

The present invention enables communication processing that is not affected by the status of the operating system by separately controlling the operating system and the micro mainframe link communication processing means in a microcomputer that performs distributed processing of processes together with a host computer. , the operating system can be used in almost the same way as when processes do not communicate.

[Conventional technology]

In the conventional example, a microcomputer system connected to a host computer system, an operating system running there, a process using a micro mainframe link running on the operating system, and data exchange with the host computer system are used. On the microcomputer system side, when a process that uses the micro mainframe link on the microcomputer system requests communication with the host computer system, the process that uses the micro mainframe link goes into a dormant state. Then, the communication process communicates with the host computer system, and when the communication request is completed, the process using the micro mainframe link enters the execution state and realizes communication with the host computer. Or, for a communication processing process that is running simultaneously with a process that requires micro mainframe link communication on the operating system, requests and data reception from the process that requires micro mainframe link communication to the communication process is The transfer is performed by an inter-process communication means provided by the operating system, and is realized by communication processing with a host computer process.

[Problem that the invention seeks to solve]

In such a conventional example, when processing communication in a microcomputer system, a process using a micro mainframe link on the microcomputer system requests communication with the host computer system, and the process using the micro mainframe link stops. state, the communication process communicates with the host computer system, and when the communication request is completed, the process that uses the micro mainframe link enters the running state and realizes communication with the host computer, so the request source If there is a process in the process that can be performed in parallel with the communication process, that process cannot be performed. In addition, requests and data reception from processes that require micro mainframe link communication to the communication process are handled by processes that are running simultaneously with processes that require micro mainframe link communication on the operating system. If the handover is performed using the inter-process communication means provided by the operation system and realized by communication processing with the process of the host computer system, the management of the resources used by the communication process is performed by the microcomputer-based operation system, and the communication with the host computer is performed. The execution of a process that performs communication processing is affected by the execution of other processes running on the operating system, and the timing of communication operations with the host computer changes depending on the status of other processes running on the operating system. It becomes necessary to absorb this in communication processing, resulting in a load on communication processing.

In either case, there is a drawback that the processing efficiency of distributed processing with the process using the micro mainframe link executed on the host computer system is reduced.

The present invention aims to eliminate such drawbacks, and aims to provide a microcomputer that does not reduce distributed processing efficiency due to micro mainframe communication.

A shared resource management means 11 is provided, which sets resources related to micro mainframe link communication independently of the operating system of the own device, and manages resources shared by the operating system of the own device and the communication processing means.

Next, the operation of this embodiment will be explained.

In the micro mainframe link execution control means 101, at startup of the operation system 12 of the microcomputer system 100, the micro mainframe link communication processing means 14, the microcomputer system execution management means 15, the communication timing generation means 16,
The shared resource management means 11 and the microcomputer system 10
0, disconnects the communication resources 104 from the operation system 12, switches the shared resources 102 from the operation system 12 to the shared resource management means 11, and after the operation system 12 is started up, communicates with the micro mainframe link communication processing means 14 and generates communication timing. When a resource request to the shared resource 102 occurs from the micro mainframe link communication processing means 14 or the operation system 12, and the microcomputer-based execution management means 1
5 issues a request m for management information of the shared resource 102, the shared resource management means 11 is activated.

The microcomputer execution management means 15 uses the communication status of the communication resources 104, the timing information of the communication timing generation means 16 that generates the communication processing timing of the micro mainframe link communication processing section 14, and the shared resource 1.
The execution of the operating system 12 and the micro mainframe link communication processing means 14 are controlled by referring to the management information of the shared resource management means 11 that manages the shared resource management means 11 that manages the mainframe link communication processing means 14. Microcomputer execution management means 15

〔Effect of the invention〕

As explained above, the present invention incorporates a micro mainframe link communication processing means and a micro convenience system execution management means outside the operation system at the time of startup of a microcomputer system. Since execution control is performed between the microcomputer's operating system and the micro mainframe link communication processing means, communication processing can be performed based on the status of communication resources independent of the operating system and is not affected by the status of the operating system. This has the advantage of being able to operate independently of communication processing with the system.

In addition, a process that uses a micro mainframe link and is executed on a microcomputer-based operating system is a process that does not use the micro mainframe link except to receive and receive data from the micro mainframe link communication processing means. Since the operation system can be used in the same way as the above, there is an effect that distributed processing can be efficiently realized on the microcomputer system when linking the microcomputer system with the host computer.
