Embodiment one
With reference to Fig. 1, show the flow chart of steps of the method for testing embodiment of a kind of on-chip study data of the present invention, specifically can comprise:
The text to be measured of step 101, reception user input;
In embodiments of the present invention, described text to be measured can comprise Chinese or English.In a particular application, can be that test macro of the present invention increases display interface, be received the text to be measured of user's input by this display interface.Certainly, in actual applications, other parameter information of user's input can also be received by this display interface, the information such as the display position of such as text to be measured, Charactes Display width and Charactes Display height.
The method of testing of on-chip study data of the present invention specifically can be applied to variously to be had in the terminal equipment of Presentation Function, such as watch-dog, due to less demanding to color displays of watch-dog, but need to ensure real-time, and 2BPPOSD uses 2bit to represent a pixel, so corresponding four kinds of color indexs, usual use 0 represents background, 1-3 represents other color index, although the color that 2BPPOSD does not have true color so to enrich, but the demand that can greatly reduce bandwidth, these features make 2BPP be applicable in watch-dog.The embodiment of the present invention is all described for the 2BPPOSD of watch-dog test, and other application scenarios is cross-referenced.

In embodiments of the present invention, when text to be measured being carried out on watch-dog Overlapping display, first need in the expansion character library set up, inquire about lattice information corresponding to each character obtained in described text to be measured, the video image that then described lattice information is added to shows.
In one preferred embodiment of the invention, the step of the lattice information that the described character read in the expansion character library set up in advance in described text to be measured is corresponding, specifically can comprise:
Step S11, the dot matrix original position that the character determined in described text to be measured is corresponding in described expansion character library;
Because English dot matrix word library is different with the formation of Chinese dot matrix word library, therefore, the process obtaining lattice information is not identical yet.In actual applications, Chinese character can adopt two internal codes to represent, namely two bytes represent.Chinese dot matrix word library is according to region-position code sequential storage, and therefore can obtain the dot matrix original position of Chinese character according to region-position code, wherein, the front two of region-position code is called district's code, and latter two become bit code.After acquisition dot matrix original position, the dot matrix of corresponding character can be read from this position.
When described text to be measured is Chinese information, can by following formulae discovery dot matrix original position:
District's code=internal code upper byte-0xa0 (1)
Bit code=internal code low byte-0xa0 (2)
Dot matrix original position=((district's code-1) × 94+ (bit code-1)) × Chinese character dot matrix byte number (3)
In actual applications, English can store according to ASCII (AmericanStandardCodeforInformationInterchange, USA standard code for information interchange), uses a byte representation.Therefore, when described text to be measured is english information, can by following formulae discovery dot matrix original position:

Receive dot matrix width information and the dot matrix elevation information of user's input.
Then dot-matrix joint number specifically can pass through following formulae discovery:
Dot-matrix joint number=dot matrix width × dot matrix height/8 × 2 (5)
Wherein, the bit number shared by each character of text to be measured that dot matrix width × dot matrix height is arranged for user, then divided by the byte number that 8 can obtain shared by each character of text to be measured, be finally multiplied by the dot-matrix joint number that 2 can obtain 2BPP form again.
Step S13, the dot matrix original position corresponding in described expansion character library according to the character in described text to be measured, read the lattice information of dot-matrix joint number corresponding to described character from described expansion character library.
After acquisition dot matrix original position, from original position, read the lattice information of corresponding dot matrix byte number, the video image that then lattice information is added to shows.
To sum up, in the embodiment of the present invention, after the text to be measured receiving user's input, the lattice information that each character in described text to be measured is corresponding can be read in the expansion character library set up in advance, described lattice information is added on video image and shows, to test display effect, due to pixel two bit representations in this expansion character library, also namely this expansion character library is 2BPP character library, so, when carrying out 2BPPOSD test, according to this expansion character library, can at the text to be measured of the display screen display 2BPP form of watch-dog.By the embodiment of the present invention, when carrying out 2BPPOSD data test, the expansion character library that can have multiplexingly set up, without regeneration test data, substantially increases testing efficiency at every turn.

Wherein, width represents character duration information, and height represents character height information.
Step S22, read each dot character in standard dot matrix word library according to described byte number, conversion process is carried out to each dot character step-by-step.Namely each point of each dot character is represented by original 1bit, and being converted to 2bit represents, obtains corresponding 2BPP character.
Because expansion character library is 2BPP character library, therefore, for each point in dot matrix, can represents by four kinds of colors, particularly, can represent with 0,1,2,3.In one preferred embodiment of the invention, described according to existing standard dot matrix word library in the order of dot character, before each dot character being carried out to the step of conversion process, described method can also comprise:
Font color, outline color and background color in expansion character library is set;
The described order according to dot character in existing standard dot matrix word library, each dot character is carried out to the step of conversion process, specifically can comprise:
According to the order of dot character in existing standard dot matrix word library, judge that whether each point in each dot character is the point in character, if so, then the color of this point is replaced with described font color; Otherwise, judge that whether this point is the point in profile, if so, then the color of this point replaced with described outline color; Otherwise, the color of this point is replaced with background color.
In a kind of application example of the present invention, according to the order of dot character in existing standard dot matrix word library, judge in each dot character, whether each corresponding position is 1, if 1, illustrate that this point is the point in character, then the color of this point is replaced with described font color, such as, represent with 2; If the position of correspondence is 0, illustrate that this point is the point in background, then judge that whether this point is the profile of character further, if so, then the color of this point is replaced with described outline color, such as, represent with 1, otherwise replace with background color, such as, represent with 0.Dot matrix word library can be converted to 2BPP character library by above-mentioned steps, and can the color of self-defined font and background color etc., make the foundation expanding character library more flexible, in addition, the present invention can arrange outline color to word, thus it is more clear that font is shown.
In a particular application, dot matrix word library can be divided into laterally storage according to the difference of bytes store mode and longitudinally store, and in the embodiment of the present invention, preferably the dot matrix unification in expansion character library is converted to horizontal storage mode.Certainly, in actual applications, also can adopt longitudinal storage mode, the present invention is not limited for the dot matrix storage mode in expansion character library.
In a kind of application example of the present invention, above-mentioned process dot matrix word library being converted to 2BPP character library can be realized by a character library crossover tool, with reference to Fig. 4, show a kind of character library crossover tool interface of the present invention schematic diagram.Wherein, what inputfile (input file) represented is existing standard dot matrix word library position; What outputfile (output file) represented is the memory location expanding character library; Width (wide) represents the character duration arranging expansion character library, and height (height) represents the character height of expansion character library; Direction (direction) represents that the dot matrix storage mode of expansion character library is horizontal or longitudinal; Dotcolor (color of point) is the color of character in expansion character library, represent with numerical value 2, foilcolor (outline color) is the outline color of character in expansion character library, represent with numerical value 1, intervalcolor (gap color) is the background color of character in expansion character library, represents with numerical value 0.
After click convert (conversion) button, this crossover tool can find standard dot matrix word library according to the standard dot matrix word library position shown in inputfile, and open this standard dot matrix word library, then byte number needed for the rear each character of conversion is determined according to the character duration width arranged and character height height, each dot character in standard dot matrix word library is read according to this byte number, conversion process is carried out to each dot character step-by-step, it is the some use dotcolor replacement of 1 in each dot character, be 0 point judge whether further again to add profile, the point that can add profile uses foilcolor to replace, remaining uses intervalcolor to replace.In actual applications, when judging whether some points can add profile, need to determine this point be whether in Fig. 3 topmost or bottom or Far Left or rightmost point, if so, then need not add profile.After character conversion process all in dot matrix word library being completed, namely generate expansion character library, the expansion character library of generation is kept at the position that outputfile specifies.After establishing expansion character library, the test of 2BPPOSD data can be carried out according to this expansion character library.
