The further technical scheme of technical solution problem of the present invention is: described font information comprises font dot array data memory location, describes the information of dot array data size.
The further technical scheme of technical solution problem of the present invention is: described font dot array data and described linear data structure be storage or separately storage continuously.
The further technical scheme of technical solution problem of the present invention is: in the described B step, the value of the font dot array data address in the described data block changes with the variation of font dot array data memory address.
The further technical scheme of technical solution problem of the present invention is: when the memory address of font dot array data is constant in the described data block, determine the value of font dot array data memory location in the described linear data structure.
The further technical scheme of technical solution problem of the present invention is: when the memory address of the font dot array data in the described data block changes, revise the value of dot matrix font data address in the described linear data structure.
The technical scheme of technical solution problem of the present invention is: make up a kind of matrix font library initialization system, comprise font storehouse parsing module, memory module, also comprise data block, to be built into data block behind the described font storehouse parsing module parsing font storehouse, described data block comprises that font dot array data and record comprise the linear data structure of font information, with described data block store in memory module.
The further technical scheme of technical solution problem of the present invention is: described font dot array data and described linear data structure be storage or storage continuously separately.
The further technical scheme of technical solution problem of the present invention is: the value of described font dot array data address changes with the variation of memory address.
The further technical scheme of technical solution problem of the present invention is: the value of described font dot array data address is initial value or modified value, described modified value be initial value and off-set value and.
The technique effect that technical solution of the present invention produces is: by designing a kind of matrix font library initialization method, the method that namely makes up data block, loading data block is carried out the initialization in font storehouse, simultaneously, by making up a kind of matrix font library initialization system, namely comprise font storehouse parsing module, memory module, data block, the process of the font storehouse being resolved, made up linear data structure operated by making up data block before initialization, had improved the initialization speed of matrix font library greatly.

Embodiment
Below in conjunction with specific embodiment, technical solution of the present invention is further specified.
The present invention designs a kind of matrix font library initialization method, comprises the steps:
A, structure font data piece: resolve the font storehouse, the font data of described parsing is arranged to data block, described data block comprises that font dot array data and record comprise the linear data structure of font information.
B, loading data block: described data block is loaded into internal memory.
As shown in Figure 1, step 100, make up the font data piece, at first the font storehouse is resolved, make up data block with the font data of resolving, described data block comprises font dot array data and linear data structure, and described linear data structure comprises record font dot array data memory location and the font information of describing the dot array data dimension information.Step 200 loads data block, and described data block comprises font dot array data after the parsing and the stored position information of font information and described font dot array data.
As Fig. 2, shown in Figure 3, described data block comprises linear data structure 1 and font dot array data 3, described linear data structure 1 comprises memory location 11, describes the information 12 of word size, the address of the corresponding font dot array data 2 of stored position information 11 storages in the described linear data structure 1.Two parts of described data block are that linear data structure 1 and font dot array data 2 can be stored or separately storage continuously.
As Fig. 2, shown in Figure 3, stored position information 11 values in the described data block neutral line data structure 1 change with the variation of memory address.The value of the stored position information 11 in the described linear data structure 1, whether memory address when looking embedded device data block being written into internal memory fixes, be divided into two kinds: under the situation that memory address is fixed, the value of the stored position information 11 of each sensing dot array data is determined in the linear data structure, can directly calculate actual value, the data block of generation does not need through the memory address correction; Under the unfixed situation of memory address, the value of the stored position information 11 in the described linear data structure 1 needs to revise, the relativity shift value of the stored position information 11 of each sensing particular glyph dot array data 3 is determined in the linear data structure, therefore, the address value of the stored position information 11 in the described linear data structure 1 be start address and offset address and, for example: with respect to the start address of data block second portion, the off-set value of the dot array data memory location of first font is 0, record-shifted value is added the modified value that start address is the memory location.
When data block is written into the internal memory use, because the font in the data block is through resolving and the linear data structure structure, therefore, directly be written into data block and namely can use font dot array data 3, save a large amount of time-consuming procedure such as resolving font storehouse and structure linear data structure in the initialization procedure, saved initialization time greatly.
As shown in Figure 4, the present invention makes up a kind of matrix font library initialization system, comprise font storehouse parsing module 4, comprise that also data block makes up module 6, described font storehouse parsing module is resolved the font storehouse, resolve the back and form font information 5, described font information 5 is built into data block by data construct module 6 again, described linear data structure comprises font dot array data 2 and record font information 12 and stores the address information 11 of described font dot array data position.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention does, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
