Alternatively, detect whether the first program code exists abnormal including: after chip powers on, obtain the code information of the first program code；Judge whether the code information of the first program code meets pre-conditioned；When the code information judging the first program code meets pre-conditioned, it is determined that the first program code does not exist exception；And when the code information judging the first program code is unsatisfactory for pre-conditioned, it is determined that the first program code exists abnormal.
The code information of the embodiment of the present invention can be one or more in code of the identifier of program code, program length, check code or predeterminated position etc., the pre-conditioned setting of the embodiment of the present invention is corresponding to above-mentioned code information, such as, take the identifier that code information is program code, the most pre-conditioned for presetting identifier or default identifier list etc..
Alternatively, code information includes marking code, it is judged that whether the code information of the first program code meets pre-conditioned including: judge that marking code is the most consistent with the first preset value；When judging marking code and the first preset value is consistent, it is determined that the code information of the first program code meets pre-conditioned；And when judging marking code and the first preset value is inconsistent, it is determined that the code information of the first program code is unsatisfactory for pre-conditioned.
The marking code of the embodiment of the present invention is for identifying the program code of the embodiment of the present invention, different marking codes can correspond to differently program code, specifically, could be arranged to store the marking code of the first program code in the position of specifying of the first memory block, such as, the front two arranging the first memory block stores the marking code of the first program code.
The embodiment of the present invention is after the marking code getting the first program code, the marking code got and the first preset value can be compared, wherein, first preset value can be one or more default marks, when the marking code got is identical with any one default mark, then description code mark is consistent with the first preset value, now, then determine that the code information of the first program code meets pre-conditioned, when the marking code got all differs with any one default mark, then description code mark is inconsistent with the first preset value, now, then determine that the code information of the first program code is unsatisfactory for pre-conditioned.
Alternatively, code information includes the check value of the first program code, it is judged that whether the code information of the first program code meets pre-conditioned including: judge whether the check value of the first program code presets check value with first consistent；The check value and first judging the first program code preset check value consistent time, it is determined that the code information of the first program code meets pre-conditioned；And the check value and first judging the first program code preset check value inconsistent time, it is determined that the code information of the first program code is unsatisfactory for pre-conditioned.
The check value of the first program code of the embodiment of the present invention can be the check code that the length computation according to the first program code obtains, or it being arranged on the identifying code etc. that in the first program code, specific bit is put, the embodiment of the present invention illustrates as a example by the check value of the first program code is for the check code that obtains according to the length computation of the first program code.
nullSpecifically，Certain the appointment position that can be set in advance in the first memory block stores the length of the first program code，Such as，The 3rd of first memory block and the 4th length for storage the first program code，After the length getting the first program code，The check value of the first program code is calculated according to default operational rule，Such as，The result each data bit addition of the length of the first program code obtained is as the check value of the first program code，And this check value and first are preset check value compare，Wherein，First presets check value can be pre-stored within the first memory block，Check value and first at the first program code preset check value identical time，Then illustrate that the code information of the first program code meets pre-conditioned，Check value and first at the first program code presets check value when differing，Then illustrate that the code information of the first program code is unsatisfactory for pre-conditioned.
Preferably, in order to improve the accuracy for program code abnormality detection result, it is judged that whether the code information of the first program code meets pre-conditioned including: judge that the marking code of the first program code is the most consistent with the second preset value；When the marking code and the second preset value judging the first program code is inconsistent, it is determined that the code information of the first program code is unsatisfactory for pre-conditioned；When the marking code and the second preset value judging the first program code is consistent, then continue to obtain the check value of the first program code；Judge that the check value and second of the first program code presets check value the most consistent；The check value and second judging the first program code preset check value consistent time, it is determined that the code information of the first program code meets pre-conditioned；And the check value and second judging the first program code preset check value inconsistent time, it is determined that the code information of the first program code is unsatisfactory for pre-conditioned.
Specifically, the embodiment of the present invention is after the marking code and the second preset value judging the first program code for the first time is identical, the check value continuing to obtain the first program code judges again, only the check value and second judging the first program code preset check value consistent time, just determine that the code information of the first program code meets pre-conditioned, by marking code and the check value of comprehensive first program code, the embodiment of the present invention detects whether first code program exists exception, such that it is able to improve the accuracy of testing result.
It should be noted that the embodiment of the present invention comprehensively Multiple Code information can detect first code program the most extremely, however it is not limited to above two, such as, it is the most abnormal that comprehensive three kinds of code informations perform to judge to detect program in machine code three times；The execution sequence that the order performing repeatedly to judge is also not necessarily limited in above-described embodiment, such as, the embodiment of the present invention can also be that first to judge whether the check value of the first program code presets check value with second consistent, the check value and second judging the first program code preset check value consistent time, further judge that the marking code of the first program code and the second preset value are the most consistent.
Alternatively, the check value obtaining the first program code includes: obtain the code length of the first program code；And the check value of the first program code is calculated according to the code length of the first program code.
Specifically, certain the appointment position that can be set in advance in the first memory block stores the length of the first program code, such as, the 3rd of first memory block and the 4th length for storage the first program code, after the length getting the first program code, calculate the check value of the first program code according to default operational rule, such as, the result each data bit addition of the length of the first program code obtained is as the check value of the first program code.It should be noted that preset operational rule to be not limited to above-mentioned operational rule, for example, it is also possible to be that the check value of the first program code is carried out Hash operation.
