Should be appreciated that general the description with the following detailed description of more than the present invention is all exemplary and explanat, and it is intended that the present invention as claimed in claim provides further explanation.
Accompanying drawing explanation
Being that they are included and constitute the part of the application in order to provide further understanding of the invention including accompanying drawing, accompanying drawing illustrates embodiments of the invention, and plays the effect explaining the principle of the invention together with this specification.In accompanying drawing:
Fig. 1 illustrates the flow chart of the basic step of the static storage area storage verification method according to the present invention.
Fig. 2 illustrates flow chart according to another preferred embodiment of the invention.
Detailed description of the invention
With detailed reference to accompanying drawing, embodiments of the invention are described now.
With reference first to Fig. 1, the figure shows the flow chart that the static storage area according to the present invention stores the basic step of verification method.This static storage area storage verification method 100 mainly comprises the steps that
Step 101: the first data are stored in static storage area；
Step 102: close this static storage area；
Step 103: read the data in this static storage area, and be the second data by the data markers read；
Step 104: compare these first data and these second data；
Step 105: according to this result of the comparison, it is judged that whether storage operation is wrong.
It will be seen that the static storage area storage verification method of the present invention is after normal storage data, read the data just deposited at once from static storage area, judge whether storage operation is wrong by comparing the two data, if errorless, then prove that storage operation is correct, exit the method；If wrong, then can point out mistake and/or again perform data Stored Procedure.So, it is possible to eliminate the subsequent operational problems caused due to data storage errors, improve reliability and the safety of product.
Discuss a preferred embodiment of the present invention in detail below in conjunction with Fig. 2, and the operation of above-mentioned static storage area storage verification method 100 and mode of operation can also be become more fully apparent by the following detailed description with distinct.
In method 200, it is first turned on static storage area (step 201), such as this step specifically includes closedown and interrupts, by corresponding sector number to be programmed, parameter is set, the first data are stored in static storage area (step 202), these first data include write offset address and data.After completing this storage operation, close static storage area (step 203), for instance this step specifically includes removing sector number data, opens interruption.
Then, in this static storage area, data are read, for instance this step includes: closes and interrupts, arranges parameter and address reading data by corresponding sector number to be programmed, open interruption, and be the second data (step 204) by the data markers read.Relatively these first data and these second data (step 205).
As an example, the first data and the second data can be multiple data, and then correspondence compares respectively.The data such as, read in step 204 are the one or more data in this static storage area.So, in this example, this step 205 is relatively compare whether these first data is consistent with these second data or whether the plurality of first data are consistent respectively with the plurality of second data.
Or, as another example, the data read in this step 204 are the data slots (data slot of the specified byte of such as stem and the specified byte of afterbody) of at least one ad-hoc location in this static storage area, and the comparison in this step 205 is whether the data slot comparing at least one the corresponding ad-hoc location in these first data is consistent with these second data.Reading manner by the sampling type of this example, it is possible to reduce need the data volume read, thus improving operational efficiency.Certainly, the present invention can also select the data manner of comparison of other forms according to actual needs.
Finally, according to this result of the comparison, it is judged that whether storage operation is wrong.
As an example, this step can specifically include: if this result of the comparison is inconsistent, then judge that storage operation is wrong and re-executes aforesaid step 201-205；If this result of the comparison is consistent, then judges that storage operation is errorless and terminate this static storage area storage verification method.
Additionally, as another example, i.e. embodiment according to Fig. 2, this step can specifically include:
If this result of the comparison is inconsistent, then judging that storage operation is wrong, and make cumulative calculation add 1 (step 209), whether the number of times continuing to judge to perform this step 201-205 is more than preset value (step 206)；
If less than this preset value, then re-execute this step 201-205；
If equal to or more than this preset value, then point out mistake (step 207), this prompting mistake is such as display error code or send alarm；
If this result of the comparison is consistent, then judge that storage operation is errorless and terminates this static storage area storage verification method (step 208).
Those skilled in the art can be obvious, the above-mentioned exemplary embodiment of the present invention can be carried out various modifications and variations without departing from the spirit and scope of the present invention.Accordingly, it is intended to make the present invention cover the amendment to the present invention and modification dropping within the scope of appended claims and equivalent arrangements thereof.
