Abstract

PURPOSE:To simultaneously perform the input of commands given from an operator and cooperative actions among plural processes by handling input received from a keyboard and a coordinate input device as well as an inter- process communication event by an application program. CONSTITUTION:A process control monitor 1 containing a process control table 2 is used together with plural application processes 3 and 3' which include an application main body 6, an integrated input/output function 5 and an inter- process communication function 4 respectively. Each of both processes 3 and 3' controls the function 4 and has the function 5 which controls the input events to handle the input events C received from a keyboard 7 and a coordinate input device 8 and an input event (f) of the inter-process communication in the same way. Therefore, the same support is possible for other processes and an operator. Thus it is possible to simultaneously perform the input of commands given from the operator and the cooperative actions among plural processes.

Description

[Detailed description of the invention] [First industrial field] The present invention relates to a multi-process integration method, particularly a multi-process integration method for interactive programs such as CAD. There is a tendency for computers to become larger and larger, and from the perspective of computing resources.

It has become difficult to combine all processes into a single execution module, and the trend is toward more distributed processing [common technology].

How to combine all program routines into one execution module, overlaying appropriate functions.

There are separate processes (tasks) for each appropriate function, and a method of transferring data between processes using a file or a dedicated shared memory.

[Conventional technology] Traditional large-scale systems using multiple processes.

It consists of a process that controls the startup and completion of each system and multiple application processes, and the control process sequentially completes each process.

Is data exchanged between each process via files?

Many use shared memory, and each process.

Basically, they do not run at the same time and proceed with processing procedures JITh.

[Problem that the invention seeks to solve]

In the conventional large-scale system configuration method using multiple processes described above, multiple processes run simultaneously.

The disadvantage was that there was no cooperative operation between them. Furthermore, since there is no generality in exchanging data between processes, C
In an interactive system such as an AD system, a drawback is that it is rarely possible to universally connect a plurality of programmatically independent programs.

[Means for solving problems]

The multiple process integration method of the present invention is a process management motor that has a process management means that manages the process names and process management motors of multiple processes running simultaneously, and controls the startup and completion of each process and inter-process communication. It consists of multiple application processes equipped with a communication means between processes and an input management means for collectively managing input from the keyboard and coordinate input device and identifying the process that generated the input event, and the application program is By handling inputs from the coordinate input device and communication events between processes in the same way, command inputs from an operator and cooperative operations between a plurality of processes running simultaneously can be performed simultaneously.

〔Example〕

Next, one embodiment of the present invention will be described in detail with reference to one drawing.

FIG. 1 is a process block diagram showing a practical example of the present invention.

The multiple process integration method shown in FIG. 1 includes a process management monitor 1 having a process management table.

Application body 6. Integrated input/output function 5. It is composed of a plurality of application processes 3.3' having an inter-process communication function 4.

The process management monitor 1 has a table containing the process names, process IDs, and process statuses of all processes under its control 9, and receives information about each process in response to a request a from each application process. to be sent back. Examples of adjustments include matching the process configuration diagram to the process name, and matching the status of each process directly. The process management monitor requests the startup and completion of other processes from each application cage.
Starts new processes and completes existing processes.

Each application process 3.3' communicates directly with other processes using interprocess event communication signals.

FIG. 2 is a schematic diagram for explaining the data structure that shows the contents of event communication. In event communication, the event sender process ID or process name.

Event type Send event content. The event data is a text data string, and its format is the same as when issuing a command to an application process from a keyboard or the like.

Also, how to reflect the execution results of each command.

The same applies to keyboard input and interprocess communication. If there are 8 responses such as acknowledgment, a response request command is issued. When each application requires a response, it issues a response event to the issuer of the input event.

Each application process 3.3' has an integrated Otakata function 5 that controls the inter-process communication function 4 and manages single-person events, and receives input events C from the keyboard 7 and coordinate input device 8 and inter-process excitation. By treating f in the same way.

The same support can be provided to other processes as well as to the operator.

〔Effect of the invention〕

The multiple process integration method of the present invention allows multiple processes to run simultaneously by treating inter-process communication events and input events from the keyboard equally, and processes can communicate with each other using inter-process communication events. In addition to cooperative operation, command requests input by the operator from the keyboard and mouse can also be handled in the same way.

Also, a limit on the number of cooperating processes.

Since there is no need to make detailed arrangements between processes, it has the effect of freely integrating multiple programs.
