Embodiment 1

[0020] Such as figure 1 As shown, the embodiment of the present invention provides a method for eliminating memory faults, including:

[0021] Step 101: Obtain the physical address information of the faulty memory space in the application program running space of the memory;

[0022] Step 102: Isolate the faulty memory space in the application program running space according to the physical address information of the faulty memory space.

[0023] In the embodiment of the present invention, the physical address information of the faulty memory space in the application program running space is obtained, and the faulty memory space of the application program running space is isolated according to the physical address information of the faulty memory space. When the memory unit fails bit by bit, it can also eliminate the memory failure and ensure the normal operation of the operating system and applications.

Embodiment 2

[0025] Such as figure 2 As shown, the embodiment of the present invention provides a method for eliminating memory faults, including:

[0026] Step 201: when the single board is started, for the application program running space included in the memory of the single board, start scanning from the first memory unit in the application program running space;

[0027] Wherein, the memory of the single board includes an operating system running space and an application program running space; the operating system running space is used to store an operating system, and the application program running space is used to store an application program.

[0028] Wherein, the memory unit is the smallest particle of the memory, and each memory unit occupies 64 bits or 32 bits, etc., and each memory unit has its corresponding physical address in the memory.

[0029] For example, see image 3 , the smallest particle in the application program running space is a memory unit. In the physical sp...

Embodiment 3

[0062] Such as image 3 As shown, the embodiment of the present invention provides a device for eliminating memory faults, including:

[0063] An acquisition module 301, configured to acquire the physical address information of the faulty memory space in the application program running space of the memory;

[0064] The isolation module 302 is configured to isolate the faulty memory space in the application program running space according to the physical address information of the faulty memory space.

[0065] Wherein, the acquisition module 301 includes:

[0066] The detection unit is used to sequentially detect each memory unit in the application program running space starting from the first memory unit in the application program running space;

[0067] The scanning unit is used to scan the memory space of a preset size backwards from the faulty memory unit when a faulty memory unit is detected, combine the faulty memory unit and the memory space to form a faulty memory spa...

Abstract

The invention discloses a method and a device for eliminating memory failure, belonging to the technical field of computers. The method comprises the following steps of: acquiring the physical address information of a failure memory space in an application program operation space of a memory; and isolating a failure memory space in the application program operation space according to the physical address information of the failure memory space. The device comprises an acquisition module and an isolation module. The method and the device can eliminate the memory failure.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method and device for eliminating memory faults. Background technique [0002] In the computer field, before the single board runs the operating system and the application program, it needs to store the operating system and the application program in the memory, and then run the operating system and run the application program stored in the memory through the operating system. [0003] Wherein, the application program running space of the single-board memory is used to store the application program. If the application program running space fails, the operating system may be restarted and the application program may not be able to run. At present, the single board can use the ECC (Error Correcting Code, error checking and correction) detection method to detect each memory unit included in the application program running space, and detect the memory unit with a failure bit; if the detect...
