Abstract

(57) [Summary] [Purpose] Only the self-tests of specific items specified in advance are executed at software reset so that they can be used immediately after software reset. [Configuration] Central processing unit 1, storage device 2, input device 3
And a display device 4, a specific program is selected in advance from various self-test programs, the self-test program is stored in the storage device 2, and the self-test program is called from the storage device 2 at the time of software reset. To execute.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an information processing device, and more particularly to an information processing device having a self-test function (self-diagnosis function).

[0002]

[Prior Art]

 In a conventional information processing device, when a software reset is performed from the power-on state (when the OS or the like is being activated), each device such as each control chip and input / output device in the central processing unit is excluded except for the memory test. The initialization of etc. is performed again. This is almost the same as the self test from the power off state.

[0003]

[Problems to be solved by the device]

 In the above-mentioned conventional information processing apparatus, since a series of self-tests are executed every time a software reset is performed, unnecessary test items are also executed, and it takes time to restart the OS. There was a problem of poor operability.

The present invention has been made in view of such circumstances, and its problem is that only a self-test of a specific item designated in advance is executed at the time of software reset, and the device can be used immediately after software reset. It is to provide an information processing device that can do it.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides a selection means for selecting a program of a specific test item from various self-test programs, a storage means for storing the selected self-test program, and a software reset time. Self-test executing means for executing the self-test program called from the storage means.

[0006]

[Action]

 At the time of software reset, only the specific self-test program selected from various self-test programs is executed in advance. Therefore, compared to the case where the self-test is executed for all test items, until the OS starts up again. Time will be shorter.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of an information processing apparatus according to an embodiment of the present invention. In the figure, 1 is a central processing unit, 2 is a storage unit, 3 is an input unit, 4 is a display unit, and the storage unit 2, the input unit 3 and the display unit 4 are controlled by the central processing unit 1. When numerical data or the like is input from the input device 3, it is processed by the central processing unit 1. The result is input to the display device 4 and stored in the storage device 2. In such an information processing device, particularly a personalized device, when the OS (operating system) or the like goes down, a soft reset (software reset) is executed to restart the OS. At this time, a self-test (self-diagnosis) is simultaneously executed.

FIG. 2 shows a test item setting method. In this figure, only the parts related to the present invention are described, and general operations required for the device are omitted. First, several patterns of test items to be executed at the time of soft reset are selected in advance from various self-test programs (step 21). Next, the program of the selected test item is stored in the memory (step 22). Finally, the execution key corresponding to each test item is set (step 23).

FIG. 3 is a flowchart showing a process at the time of soft reset. A soft reset is executed by pressing the execution key set by the user (step 31). The program of the test item corresponding to the execution key is called from the memory and executed (step 32). When the self-test ends, the OS starts up (step 33).

[0011]

[Effect of the device]

 According to the information processing device of the present invention, only a specific self-test program selected from various self-test programs in advance is executed at the time of software reset, so that the self-test is executed for all test items. Compared to the above case, it takes less time until the OS starts up again, and it can be used sooner after software reset.
