Abstract
The invention relates to the technology of data storage, in particular to a method of storing important data of televisions. The invention provides a reliable and effective method of storing important data of televisions. The technical proposal is as follows: a polishing unit region stored with programs and rest spaces in a FLASH memory of televisions into a plurality of storage units, recording initial and end addresses of the storage units; each storage unit stores one parameter, and the size of the storage space of the parameters is ensured according to the lengths of the parameters; parameters needing stored are stored to find out the storage units of the parameters when the amendment is needed, and the values of the amended parameters are then stored after the current values; the current value is the first non-empty area storage value found from the end address when the transfer is needed. Adopting the storage method in the invention saves the EEPROM memory, reduces the cost, effectively uses the FLASH memory space and reduces the chance of losing the data.
Description
Technical field
The present invention relates to data storage technology, relate in particular to a kind of television set important data storage method.
Background technology
At present, also have the data quite a lot can not be in the television set with software solidification, still need to be stored in other nonvolatile storage, traditional selection is to be stored in the EEPROM (Electrically Erasable Read Only Memory) that follows the IIC serial communication protocol, usually the microprocessor of television set all is the speed communication with it with tens Kbps, finishes corresponding read-write operation.Though this comparatively simple and direct communication modes has brought convenience for development and Design, the geometric parameter of some important parameters of television set Default Value such as factory's debugging, chip parameter, option parameter etc. all are stored among the EEPROM.But because Core of TV set need work long hours in the environment of high pressure, high heat, many static, will be unfavorable for the performance of reliability, anti-static ability and the antijamming capability of communication, EEPROM also very easily is interfered and causes significant data to be made mistakes.
Summary of the invention
Technical problem to be solved by this invention is: be subject to operational environment influence and the shortcoming of obliterated data proposes a kind of reliable and effective television set important data storage method at storage mode of the prior art.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of storage means of television set significant data may further comprise the steps:
A. having program stored therein and the module unit area dividing that clashes of remaining space is arranged in FLASH (flash memory) memory with television set is several memory cell;
B. parameter of each cell stores, the initial and end address of writing down this unit;
C. determine the memory space of this parameter according to each parameter length, will need stored parameters to store said memory cells into;
When d. needing to revise certain parameter, find the memory cell of this parameter, and then the parameter value of revising is stored in currency after, if when being stored to the end address then the content of eraseable memory unit and the parameter of revising is stored to initial address after;
When e. calling certain parameter, the area stores value from the end address reverse find to first non-NULL is exactly the parameter current value.
Described parameter is divided into user data and non-user data, when parameter is non-user data, also wants execution in step between step c and steps d:
F. stored parameters is cured.
Described FLASH memory is the external memory of television set microprocessor.
Described FLASH memory is the internal memory of television set microprocessor.
The invention has the beneficial effects as follows: do not need significant data is stored among the EEPROM, saved EEPROM, reduced cost, effectively utilized the FLASH storage space, reduced the chance of loss of data.
Description of drawings

Fig. 2 is non-storage of subscriber data parameter schematic diagram;
Fig. 3 is a storage of subscriber data parameter schematic diagram.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
With reference to Fig. 1, for storage means of the present invention, be several memory cell at first with having program stored therein in the external of television set microprocessor or the built-in FLASH memory and erase block unit (block) area dividing of remaining space being arranged, parameter of each cell stores, and the initial and end address of writing down this memory cell, determine the memory space of this parameter again according to the length of each parameter, will need stored parameters to store said memory cells at last.When needing to revise certain parameter, find the memory cell of this parameter, and then the parameter value of revising is stored in currency after, be that memory space is full the time if be stored to the end address, wipe the parameter in this memory space, amended parameter is begun to deposit in from initial address.In the time of need calling certain parameter, be exactly the parameter current value from the area stores value of first non-NULL of end address reverse find.
Above-mentioned said parameter is divided into non-user data and user data.Wherein, non-user data is that television set is stored in the maintenance/factory/data such as design in the FLASH memory when dispatching from the factory.User data is that television set is stored in image in the FLASH memory, sound when dispatching from the factory, user such as tuning adjusts data.The FLASH memory can be the internal or external memory in the television set microprocessor.
For non-user data, its memory allocation is referring to Fig. 2, is 128KB as the block cell size of FLASH memory, and certain subprogram takies 64KB, and so non-user data can take remaining 64KB space.The memory space of distributing to parameter D is ox10000 to ox10078, promptly can store 20 address values, and initial parameter D_0 is stored among the 6Byte that ox10000 begins, and then D_0 storage during modification, when calling, reverse find non-NULL regional parameter values is solidified regional intrinsic parameter simultaneously.
For user data, its memory allocation is referring to Fig. 3, when the block unit of FLASH memory is bigger, the boot program can not take whole block district, with storage of subscriber data in the block unit at boot program place, distribute the zone of certain byte number as memory space after the boot program, for each parameter, the initial address of each parameter is fixing, during certain parameter of modification of program, after new modification value was placed on initial value, parameter i_n represented the n time modification value of parameter i.During call parameters, determine the parameter memory location, call from memory space end address reverse find non-NULL regional parameter values then by initial address.
