Embodiment
In the middle of instructions and follow-up claim, used some vocabulary to censure specific element.The person with usual knowledge in their respective areas should understand, and hardware manufacturer may be called same element with different nouns.This instructions and follow-up claim are not used as distinguishing the mode of element with the difference of title, but the criterion that is used as distinguishing with the difference of element on function.Be an open term mentioned " comprising " in the middle of instructions and the follow-up request in the whole text, so should be construed to " comprise but be not limited to ".In addition, " couple " speech and comprise any indirect means that are electrically connected that directly reach at this.Therefore, be coupled to one second device, then represent this first device can directly be electrically connected in this second device, or be electrically connected to this second device indirectly by other devices or connection means if describe one first device in the literary composition.
See also Fig. 3, Fig. 3 is the embodiment synoptic diagram of the present invention to the device of display function programming.Display function programmer 300 includes storer 310, program code programmer 320 and program code checking module 340.Storer 310 stores and is used for the functional programs code of refresh display.Program code programmer 320 is coupled to the storer 330 of storer 310 and display, and 340 of program code checking module are coupled to program code programmer 320.In the present embodiment, display can be monitor, simulated television or Digital Television.The present invention who please consults Fig. 4 simultaneously works out the process flow diagram of display function, with further understanding operating process of the present invention.In the time of the refresh display function, program code programmer 320 reads the program code (step S410) of one section preset length from storer 310, and the program code with this preset length sends program code checking module 340 to then.The program code of this preset length is a part that is stored in the program code in the storer 310.As described in prior art, the storer 330 of display is generally flash memory, is to be unit of program with the data page during its programming data, and the data volume of data page has a maximal value that limits; The data volume that program code comprised of this preset length promptly is equal to the data volume of data page, therefore can not surpass the maximal value of this qualification.The maximal value of supposing this qualification is 256 bytes, and then the data volume that program code comprised of the data volume of this data page or this preset length can be less than or equal to 256 bytes, may be 256 bytes, 128 bytes, 64 bytes or the like.
In step S420, program code checking module 340 checks whether the program code of this preset length meets certain preset state, if the program code of this preset length meets this preset state, then program code checking module 340 will produce a control signal and be sent to this program code programmer 320.On behalf of the logical value of all positions (bit) of the program code of this preset length, this preset state be all 1, if be unit with the byte, the data mode of then representing each byte and being presented is all FF (hexadecimal).Therefore if the program code with preset length of 256 bytes meets this preset state, then its all positions (256x8) are all logical value 1, or the data mode of 256 bytes is all FF (hexadecimal).The personage who has the knack of flash memory can understand, flash memory is before writing data, and the operation that can remove earlier is after removing finishes, the logical value of each of flash memory can become 1, that is the data mode of each byte is all FF (hexadecimal).Therefore the program code when preset length meets this preset state, then when the program code with this preset length writes the storer 320 of display, the storer 320 of display need not the logical value of dirty bit, that is to say, when in fact writing this kind data, do not need fully physically the storer 320 of display is carried out any operation.So when program code programmer 320 does not receive this control signal, program code programmer 320 is with regard to the program code with the current preset length that reads, according to its relative position in storer 310, write the storer 330 (step S430) of display; And when program code programmer 320 received this control signal, program code programmer 320 was not just carried out the operation that writes.
In order more clearly to describe above-mentioned operation, see also Fig. 5, Fig. 5 be block program code stored in the storer 310 510 with the storer 330 of display in the synoptic diagram of data mode of block to be written 520.Show as Fig. 5, part in block 510 required storages 310, block 520 is a block to be written in the storer 330 of display, the program code 512,516 of preset length does not meet this preset state, and the program code 514 of preset length meets this preset state, that is to say, the program code 512,516 of preset length can be considered as the non-blank-white section of program code, and the program code 514 of preset length can be considered as the blank section of program code.When operation, program code programmer 320 reads the program code 512 of preset length from block 510, and the program code 512 of preset length is sent to program code checking module 340 tests, because the program code of preset length 512 does not meet above-mentioned preset state, so program code checking module 340 does not produce control signal, and program code programmer 320 is promptly according to the relative position of program code 512 in block 510 of preset length, it is write in the block 520, form a data page 522 of block 520.
Then, whether program code programmer 320 determining program codes have all read finish (step 440), finish if all read, and then finish the flow process of program code; And it is described to hold epimere, because the program code in the block 510 does not read as yet and finishes, this moment, the program code programmer can read the program code 514 of next section preset length again from storer 310, and the program code 514 of preset length is sent to program code checking module 340 tested.Because the program code of preset length 514 meets above-mentioned preset state, so program code checking module 340 can produce control signal, and program code programmer 320 promptly can skip over the operation that the program code 514 of preset length is write block 520 according to this control signal, therefore can save the time of the program code 514 of programmed preset length.Similarly, the mode that reads, checks and write of the program code 516 of preset length is identical with the program code 512 of preset length, therefore can produce data page 526 on the corresponding position of block 520, data page 524 then is the program code 514 that corresponds to preset length.Above-mentioned step repeats always, all is written into the storer 330 of display up to program code.
As mentioned above, in device of the present invention, program code is before the storer that is written into display, all can be subjected to the check of program code checking module, if the program code that is about to be written into is the section of a blank, then can skip over the step that writes this blank procedure code, make the process of whole program code can save a large amount of time.
The above only is preferred embodiment of the present invention, and all equivalences of carrying out according to claim of the present invention change and revise, and all should belong to covering scope of the present invention.
