Abstract
The invention provides a device and a method for detecting memory errors, wherein the device comprises a detection module for detecting a memory, a monitoring module connected with the detection module and a warning module connected with the monitoring module, and the detection module is used for sending an error warning signal to the monitoring module when a memory error is detected; the monitoring module is used for suspending memory detection and sending a driving signal after the error warning signals are received; and the warning module is used for receiving the driving signal and is driven by the driving signal to send a warning signal. The method comprises the following steps: when the memory error is detected, sending the error warning signal; suspending the memory detection; and processing the error warning signal and generating the warning signal which sends an alarm on the memory errors. The device and the method can send the warning signal in time to avoid system shutdown.
Description
[technical field]
The present invention relates to the memory test technology, particularly a kind of device and method that is used to detect EMS memory error.
[background technology]
The ECC of test memory (Error Checking and Correcting, Chinese be " in bug check and the correction ") test procedure, test process is as follows:
1. the value of the relevant register of detection computations machine north bridge if find to have unusually, upgrades recording unusual file.
2. the inspection of application testing program timing records unusual file, notes abnormalities reporting errors.
The shortcoming application testing program of this mechanism finds that the ECC mistake is untimely, makes test procedure can not in time obtain handling, what is more, and the ECC mistake system that the makes machine of delaying continuously.
[summary of the invention]
Fundamental purpose of the present invention is to provide a kind of device and method that is used to detect EMS memory error, can in time find EMS memory error.
For reaching above purpose, the invention provides a kind of device that is used to detect EMS memory error, it comprises: the alarm module that is used to detect the detection module of internal memory, the monitoring module that is connected with detection module and is connected with monitoring module, and described detection module is used for when detecting EMS memory error, sends the false alarm signal to monitoring module; Described monitoring module is used for ending to detect internal memory and send drive signal after receiving the false alarm signal; And described alarm module is used to receive drive signal and by described drive, send alarm signal.
The present invention also provides a kind of method that is used to detect EMS memory error, and it may further comprise the steps: when detecting internal memory generation mistake, send the false alarm signal; End to detect internal memory; The false alarm signal is handled, produced the alarm signal that EMS memory error is given the alarm.
Compared with prior art, the device and method that the present invention is used to detect EMS memory error can send alarm signal, thereby can point out the tester in time to obtain EMS memory error and handle accordingly, to avoid system's machine of delaying.
[description of drawings]
Fig. 1 is the functional-block diagram that the present invention is used to detect the device of EMS memory error.
Fig. 2 is the process flow diagram that the present invention is used to detect the method for EMS memory error.
[embodiment]
See also shown in Figure 1, the present invention is mainly used under the linux environment, wherein, the device 200 that is used to detect EMS memory error is applicable to the mistake that detects internal memory 100, the device 200 of described detection EMS memory error comprises: be used to detect the detection module 21 of internal memory 100, the monitoring module 31 that is connected with detection module 21 and the alarm module 32 that is connected with monitoring module 31, and when detection module 21 detects internal memory 100 generation mistakes, send the false alarm signal; Described monitoring module 31 is used for ending to detect internal memory and send drive signal after receiving the false alarm signal; And described alarm module 32 is used to receive drive signal and by described drive, send alarm signal.Wherein, described alarm module 32 can be audible alerts module or video alarm module.
Please in conjunction with consulting Figure 1 and Figure 2, the method that the present invention is used to detect EMS memory error may further comprise the steps:
Step 501: detect described internal memory;
Step 502: detect described internal memory and whether produce mistake; Produce when wrong when detecting described internal memory, then change step 503 over to; And do not produce when wrong when detecting described internal memory, then continue execution in step 501;
Step 503: send the false alarm signal;
Step 504: end to detect described internal memory;
Step 505: the false alarm signal is handled, produced the alarm signal that described EMS memory error is given the alarm; Wherein, described alarm signal can be audible alerts signal or video alarm signal; The tester hears or sees and just can find EMS memory error behind the alarm signal and handle accordingly, to avoid system's machine of delaying.
