Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing apparatus capable of running multiple operating systems. especially,
The present invention relates to an information processing device that allows you to select an operating system and run a program without any discomfort.

0002

[Background Art] A program is executed by selecting a program, for example, by inputting the program name or by displaying the program name or icon and asking the user to select it, and then specifying startup parameters to run on the operating system. A desired program is executed by passing it directly to the program starting section.

Conventionally, in an information processing apparatus having a plurality of operating systems, as shown in FIG.
It was provided for each operating system and was assumed to operate under the same operating system 20, 30.

[0004] In this case, the programs 23, 33 that can be selected by the program selection units 21, 31 are limited to programs that are compatible with the operating systems 20, 30 on which the program selection units 21, 31 themselves operate.

[0005]

[Problems to be Solved by the Invention] However, in the above-mentioned conventional configuration, if you want to execute the program 33 running on the operating system 30 after the execution of the program 23 on the operating system 20 is completed, you need to use the operating system on which the program 33 you want to run runs. This has the problem that the system 30 must be activated consciously.

[0006] The present invention solves the above-mentioned conventional problems by providing a device that allows users to select programs even on other operating systems and to use the functions of programs without making the user aware of the operating system. is intended to provide.

[0007]

[Means for Solving the Problems] In order to solve the above problems, the information processing device of the present invention includes a parameter extraction section that extracts program startup parameters from a program, and a parameter registration section that stores the program startup parameters in a parameter storage section. a first operating system having a system determining unit that determines an operating system for executing a program; and a first system switching unit that switches to a second operating system that has been determined by the system determining unit; a system restart unit that boots the system and restarts the first operating system after the program has finished executing; a parameter reading unit that reads the program startup parameters from the parameter storage unit; a second system having a second system switching section for switching to
It is equipped with an operating system.

[0008]

[Operation] With this configuration, if it is determined that a program is to be executed in the second operating system on the first operating system, the program is switched to the second operating system, the second operating system is started, The program is executed. At this time, since the startup parameters of the program are stored in the parameter storage section, the startup parameters are not destroyed even when the operating system is switched. Also,
When the execution of the program is completed, the system switching unit can return control to the first operating system.

[0009] This allows the user to use desired program functions without having to be conscious of switching operating systems.

[0010] If the program runs on the first operating system, the system is not switched and control is transferred to the conventional program starting means on the first operating system. In conventional program starting means, system switching is not performed after a desired program ends. The operation in this case is similar to the conventional technology.

[0011]

[Embodiment] An embodiment of the present invention will be explained based on FIG.

FIG. 1 is a block diagram of an information processing device according to the present invention, in which a first operating system 1 that the device starts up includes a program selection unit 3 for selecting a program to be executed from a plurality of programs; 4
A parameter extraction unit 6 extracts parameters for program startup and an operating system identifier from the program information 5 of the first operating system 1 and the second operating system.
a parameter registration unit 8 that stores parameters for program startup in a parameter storage unit 7 interposed between the second operating system 2, a system determination unit 9 that determines the operating system based on the operating system identifier, and a second operating system that switches to the second operating system. A first system switching unit 10 and a first program starting unit 11 that starts a program executed on the first operating system 1 are provided. Further, on the second operating system 2, there is a parameter reading section 12 that reads parameters for starting a program from the parameter storage section 7, and a second operating system that starts a program to be executed on the second operating system 2.
a program starting unit 13, and a second system switching unit 1 that returns control to the first operating system 1.
4 is provided. A system restart unit 15 is provided between the first operating system 1 and the second operating system 2 to start up the second operating system 2 and to restart the system after program execution on the second operating system 2 is completed. The first operating system 1 is restarted.

The operation of the information processing apparatus of the present invention will be explained below. When the information processing device is started, the program selection unit 3 operates on the first operating system 1, a desired program 4 is selected, and the parameter extraction unit 6 extracts program startup parameters from the program information 9 given together with the program 4 itself. , and an operating system identifier are extracted, respectively. The program startup parameters are stored in the parameter storage section 7 by the parameter registration section 8. On the other hand, the operating system identifier is sent to the system determination section 9. When the system determination unit 9 determines that the program is executed on the second operating system 2, the first
The second operating system identifier is output from the system switching unit 10, and the second program starting unit 13 starts operating as the first program to operate on the second operating system 2.

Next, in the second program starting section 13, the parameter reading section 12 reads out the program starting parameters from the parameter storage section 7.
This is sent to the second program starting section 13 and the program 4 is started.

When the execution of the program 4 is completed and control returns to the second program starting unit 13, the second system switching unit 14 sends the identifier of the first operating system 1 to the system restarting unit 15. By issuing the first operating system 1, the first operating system 1 is restarted and control is returned to the program selection section 3.

[0016] This allows the user to use a desired program even if the program runs on a different operating system without having to be conscious of starting the system.

If the system determining section 9 determines that it is the first operating system, control is transferred to the first program starting section 11, which operates as before.

[0018]

As described above, according to the present invention, it is possible to utilize the functions of a desired program without making the user conscious of switching the operating system.

[0019]Also, in the above explanation, there are two bootable operating systems for simplicity, but
According to the present invention, even if a bootable operating system is added, it can be easily handled with the same configuration.
