The invention only needs to adopt one software version to be written into FLASH with different internal structures, in addition, only uniform input information such as data content to be written, the size, the writing target address and the like needs to be provided in use, and the automatic compatible processing on FLASH with different internal structure can be realized. The use is simple, and mistakes are not easy to occur. The invention has the effect of prolonging the service life of FLASH, and is applicable to the development of embedded software.

Description

A kind of software processing method of the automatic compatible with multiple model FLASH based on set-top box

[technical field]

The present invention relates to field of embedded software, specifically be meant a kind of software processing method of the automatic compatible with multiple model FLASH based on set-top box.

[background technology]

Along with the development of digital TV terminal, function is become stronger day by day, and client's demand personalization difference is also day by day obvious simultaneously.The difference of demand has proposed challenge to the digital TV set-top box design of hardware and software.With the main components and parts FLASH on the set-top box, traditional digital TV set-top box is at the FLASH of different capabilities, different model, must use different designs, must do different software operations at the characteristic of the FLASH of different model simultaneously; This just causes needs to use different software corresponding with the FLASH of different model.Production and management cost are caused waste.

[summary of the invention]

Technical problem to be solved by this invention is to provide a kind of software processing method of the automatic compatible with multiple model FLASH based on set-top box, be that a kind of outside only need provide data content, the size that need write and write destination address, the software processing method of the FLASH of automatic compatible processing different internal structure.

The present invention solves the problems of the technologies described above by the following technical solutions:

A kind of software processing method of the automatic compatible with multiple model FLASH based on set-top box comprises the steps:

Step 100: beginning;

Step 101: the compatible Flash list data list of definition in the program context environment;

Step 102: configuration program voltage VPP;

Step 103: give relative initial address;

Step 104: from Flash list data list, obtain corresponding piece number and corresponding block size;

Step 105: the data of from the data buffer zone, taking out corresponding block size;

Step 106: to the write operation of programming of corresponding FLASH piece;

Step 107: the data buffer zone size is deducted the data length that has write, and relative address adds the data length that writes;

Step 108: the validity of judging the address according to the reference address of input; Be to change step 109 over to; , do not change step 110 over to;

Step 109: whether the judgment data buffering area is empty, and buffer size is not 0 and changes step 103 over to, writes until the data buffer zone data and finish;

Step 110: discharge program voltage VPP;

Step 111: finish.

The invention has the advantages that: only need to adopt a software version, write the FLASH of different internal structure, and using only need provide data content, the size that will write and write unified input information such as destination address, gets final product the FLASH of automatic compatible processing different internal structure.Use simply, be difficult for makeing mistakes, and play the effect in the useful life that prolongs FLASH, be applicable to the exploitation of embedded software.

[description of drawings]

The invention will be further described in conjunction with the embodiments with reference to the accompanying drawings.

Fig. 1 is the theory diagram of a kind of FLASH data automatic identification writing method based on set-top box of the present invention.

Fig. 2 is the flow chart of a kind of FLASH data automatic identification writing method based on set-top box of the present invention.

[embodiment]

Fig. 1 is the theory diagram of a kind of FLASH memory data automatic identification writing method based on set-top box of the present invention.

The method of the controlled transmission of " Data Control " expression data among the figure, i.e. the software processing module that the present invention describes; The storage that need write is in random asccess memory; Data are by the control of set-top box master chip, and the method that writes according to data automatic identification writes data in the FLASH memory.Thereby finish this software flow.

Fig. 2 is the flow chart of a kind of FLASH data automatic identification writing method based on set-top box of the present invention.Mainly comprise the steps:

Application configuration: preset the feature of FLASH, set up the data list structure of FLASH feature;

Read information: according to type and the feature of the FLASH that discerns, invoking compatible program reads corresponding FLASH characteristic information;

Carry out read-write motion:, call corresponding read-write driver and carry out read-write motion according to the FLASH type and the model of identification.

Concrete detailed step is as follows:

Step 100: beginning;

Step 101: the compatible Flash list data list of definition in the program context environment;

Step 102: configuration program voltage VPP;

Step 103: give relative initial address;

Step 104: from Flash list data list, obtain corresponding piece number and corresponding block size;

Step 105: the data of from the data buffer zone, taking out corresponding block size;

Step 106: to the write operation of programming of corresponding FLASH piece;

Step 107: the data buffer zone size is deducted the data length that has write, and relative address adds the data length that writes;

Step 108: the validity of judging the address according to the reference address of input; Be to change step 109 over to; , do not change step 110 over to;

Step 109: whether the judgment data buffering area is empty, and buffer size is not 0 and changes step 103 over to, writes until the data buffer zone data and finish; Step 110: discharge program voltage VPP;

Step 111: finish.

The present invention only need adopt a software version, writes the FLASH of different internal structure, and uses and only need provide data content, the size that will write and to write unified input information such as destination address, gets final product the FLASH of automatic compatible processing different internal structure.Use simply, be difficult for makeing mistakes, and play the effect in the useful life that prolongs FLASH, be applicable to the exploitation of embedded software.
