In step 201, by the first frame buffer zone in current frame data write memory to be shown in this business datum.
Wherein, business datum can be specifically the business datum that need to be shown to the user, exemplarily, it can be the Query Result that the user carries out the data query business, it can be also the view data that image is processed service processing result, can also be interface data, the interface data of the user interactive business of applying unit for example.The content of business datum to be shown can be picture, word or the data such as meet, and with the form tissue of frame data.By the first frame buffer zone in current frame data write memory to be shown in this business datum, complete the processing of playing up for the treatment of the display frame data and operate, business datum to be shown is ready in internal memory, treat follow-up output display.
In step 202, the current frame data in the first frame buffer zone is transferred to display controller, the current frame data of being controlled in the first frame buffer zone by display controller shows in the enterprising line output of display interface; And in the process of the current frame data output display in the first frame buffer zone, next frame data and current frame data more to be shown, obtain the next frame data from frame data identical in current frame data and next frame data with current frame data in different frame data.
Those skilled in the art should know, display controller is to display transmission frame data, and necessary control signal is provided.For example, the display controller of liquid crystal display (Liquid Crystal Display, LCD) transmits frame data to be shown, provides necessary control signal to control LCD output display frame data simultaneously to LCD.Current frame data in the first frame buffer zone is transferred to display controller, control current frame data in the first frame buffer zone by display controller and show in the enterprising line output of display interface, the output display of frame data can be corresponding to the demonstration that refreshes of a display screen.
Current frame data in the first frame buffer zone carries out in the process of output display, next frame data and current frame data more to be shown, obtain the next frame data from frame data identical in current frame data and next frame data with current frame data in different frame data.
Shown in Fig. 3 (a), Fig. 3 (a) shows the first frame buffer zone described in the embodiment of the present invention and frame data schematic diagram identical and different in the second frame buffer zone.Take interface data as example, and each list items, for example, can be a menu item, an icon etc.Current frame data in the first frame buffer zone comprises list items 1 to list items 5 data, next frame packet to be shown contains list items 2 to list items 6 data, by comparing, obtaining the next frame data is that list items 2 is to list item 5 data with frame data identical in current frame data, in the next frame data, from frame data different in current frame data, be list items 6 data, list items 1 data no longer show.Need explanation the time, different frame data can compare with different data modes, for example, take view data as example, take image block as unit, can be by obtaining identical and different image block data between adjacent two frames.
In step 203, will in the next frame data, with frame data identical in current frame data, be written back to the second frame buffer zone in internal memory, and will in the next frame data, from frame data different in current frame data, write the second frame buffer zone.So far, in the second frame buffer zone to deposit and complete next frame data.In step 203, identical frame data are directly in internal memory, to carry out write-back, and these frame data complete the preparation of output display after being written back to the second frame buffer zone in internal memory, treat follow-up output display.The ground that compares, different frame data are in write memory, to realize the playing up in internal memory of different frame data processed to operation from internal memory.Treat the operation of playing up of display frame data, comprise according to the frame data content and being ready in internal memory, such as comprising: operation is processed in the filling of the drafting of image window, color pixel value etc.
Shown in Fig. 3 (b), the figure shows according to business datum display processing method embodiment provided by the present invention, to the write-back of frame data to be shown in the second frame buffer zone and the schematic diagram of write operation.Be depicted as example with above-mentioned Fig. 3 (a), in step 203, as shown in Figure 3 (b), by the next frame data with frame data identical in current frame data, list items 2 to list items 5 data that are about to the first frame buffer zone in internal memory are written back to the second frame buffer zone in internal memory.By list items 6 data from other zones, exterior storage zone for example, the second frame buffer zone in write memory.
Easily understand, if two frames are identical, do not need to carry out new writing, but the current frame data in the first frame buffer zone all is written back to the second frame buffer zone in internal memory.
The business datum display processing method example according to the present invention and unrestricted, by the next frame data when frame data identical in current frame data are written back to the second frame buffer zone, can also, according to next frame data and the display position of frame data in next frame identical in current frame data, identical frame data be written back to zone corresponding in the second frame buffer zone in internal memory.
In step 204, the next frame data of being controlled in the second frame buffer zone by display controller show in the enterprising line output of display interface.
In this business datum display processing method embodiment, by the comparison to adjacent two frame data, identical data carried out to write-back in internal memory, be about to first frame buffer zone of frame data identical in adjacent two frames in internal memory and be written back to the second frame buffer zone, only by the second frame buffer zone in different frame data write memories, can reduce and reduce the time of frame data write memory, display controller is controlled can carry out the demonstration that refreshes of frame data quickly, has improved frame data and has shown the speed refreshed.
As exemplary comparison, situation for single buffer zone in prior art, and during the working model that applying unit and display controller are serial, the time that frame data to be shown is write to the buffer zone needs is 30ms, the time that display controller is controlled the output display frame data to be needed is 20ms, one frame data are corresponding to an interface display, and now the displaying time at an interface needs 30+20=50ms, within 1 second, refresh 20 frames.
If the situation of considered frame datarams write-back not, when the situation of first, second two block buffer is arranged in internal memory, applying unit and display controller can be operated in parallel working model, the time that frame data to be shown is write to the buffer zone needs is 30ms, the time that display controller is controlled the output display frame data to be needed is still 20ms, it is MAX(30 that the now demonstration at an interface needs the time, 20)=30ms, within one second, refresh 33 frames, speed has improved 65% than prior art, MAX() for getting max function.
In business datum display processing method embodiment provided by the present invention, due to the write-back adopted in internal memory, avoided the certificate of the same number of frames in frame data to be shown write memory again, avoided the operation of playing up to the same number of frames certificate, and only by different frame data write memory buffer zones, thereby frame data to be shown can be write to the time shorten of buffer zone to 15ms, the time that display controller is controlled the output display frame data to be needed is 20ms, it is MAX(15 that the now demonstration at an interface needs the time, 20)=20ms, 50 frames within one second, have been refreshed, speed has improved 150% than 20 initial frames.
It will be recognized by those skilled in the art that the debug function that the calculating in above processing time can provide by operating system, obtain respectively the Millisecond time of interframe, thereby calculate, obtain the processing time.
The business datum display processing method example according to the present invention, the method further can also comprise: the current frame data of identifying in the first frame buffer zone shows whether complete in the enterprising line output of display interface, show and complete in the enterprising line output of display interface in response to current frame data, in the process of the current frame data output display in the second frame buffer zone, another frame data more to be shown and next frame data, obtain another frame data and frame data identical in the next frame data, and another frame data and frame data different in the next frame data, another frame data are written back to the first frame buffer zone with frame data identical in the next frame data, and another frame data are write to the first frame buffer zone from frame data different in the next frame data, another frame data are next frame data frame data subsequently in business datum, and the next frame data of identifying in the second frame buffer zone show whether complete in the enterprising line output of display interface, show and complete in the enterprising line output of display interface in response to the next frame data, in the process of the current frame data output display in the first frame buffer zone, another frame data more to be shown and another frame data, obtain another frame data and frame data identical in another frame data, and another frame data and frame data different in another frame data, another frame data are written back to the second frame buffer zone with frame data identical in another frame data, and another frame data are write to the second frame buffer zone from frame data different in another frame data, another frame data are another frame data frame data subsequently in business datum.
In above embodiment, between the first frame buffer zone in internal memory and the second frame buffer zone, cooperatively interact, prevent that frame data from being rewritten in the output display process, carried out the whether completed identification of output display, recognition result is after the frame data output display in this buffer zone completes, just in the process of the frame data output display in another buffer zone, frame data and adjacent previous frame data more backward, then according to result relatively, this buffer zone is carried out to write-back, write operation, realized showing and writing parallel mode of operation, improve frame data and shown the speed refreshed, also improve the consistance of output display frame data simultaneously, avoid the appearance of flower screen phenomenon.
Can adopt various internal memory writing mode well-known to those skilled in the art that frame data are write to frame buffer zone, the business datum display processing method example according to the present invention, specifically can be by applying unit by direct memory access (Direct Memory Access, DMA) mode writes the first frame buffer zone by current frame data to be shown from external memory unit, and will in the next frame data, from frame data different in current frame data, from external memory unit, write the second frame buffer zone.
Those skilled in the art will be appreciated that, adopt the advantage of dma mode transmission data, for example, with interrupt mode, compare, because dma mode does not need the participation of central processing unit, and, in the process of data write memory, memory address is revised, is transmitted the counting of word number etc., also with hardware circuit, directly realizes.Therefore, dma mode further improves the speed of frame data write memory, also is conducive to save the central processing unit resource.
The business datum display processing method example according to the present invention, because obtaining frame data from two different buffer areas, display controller carries out output display, therefore, before the frame data by a buffer zone are transferred to display controller, the frame data that can also whether be disposed in another buffer zone to display controller are identified, confirm in display controller transmission frame data again under idle state, avoid frame data being sent to display controller and can not showing, the frame data that bring thus block or frame data are retransmitted.
Particularly, currently to display controller display controller was controlled to next frame data in the second frame buffer zone before the enterprising line output of display interface shows, the method can also comprise: whether the identification display controller is disposed to the frame data output display in the first frame buffer zone, be disposed in response to the frame data output display in the first frame buffer zone, the frame data in the second frame buffer zone are transferred to display controller; And identification display controller whether the frame data output display in the second frame buffer zone is disposed, in response to the frame data output display in the second frame buffer zone, be disposed, by the next frame data transmission in the first frame buffer zone to display controller.
Business datum in above each embodiment, described in step 201, can be the Query Result that the user carries out the data query business, can be also image process business view data out, or the interface data of the user interactive business of concrete applying unit.
Due to the business datum of different business operational correspondence, the data volume size of the same number of frames certificate between adjacent two frames normally can be distinguished.For example, carry out the interface data of user interactive by applying unit for the user, under a lot of scenes, in front and back two frame data to be shown, a lot of data are identical.For instance, the user arrives mobile cursor under different menu bars on operation interface, former and later two show that between the frame data of exporting, difference only is to demonstrate different drop-down menus, perhaps in the operation interface of slip icon, former and later two show that the frame data of output are respectively show first to the 5th icon and show second to the 6th icon, its difference only is not show first icon, and the 6th icon is shown.For this reason, can be identified this class business datum, when belonging to specific business datum, that carries out the consecutive frame data relatively reaches write-back, otherwise, can not carry out the comparison of consecutive frame data, directly by another buffer zone in the whole write memories again of next frame data.
Therefore, in another embodiment of business datum display processing method of the present invention, at the current frame data in controlling the first frame buffer zone by display controller when the enterprising line output of display interface shows or the current frame data in controlling the first frame buffer zone by display controller after the enterprising line output of display interface shows, can also comprise: whether applying unit is identified this business is the user interactive business; If this pending business is the user interactive business, carry out in the process of the current frame data output display in the first frame buffer zone next frame data more to be shown and the operation of current frame data; Otherwise, in the process of the frame data output display in the first frame buffer zone, by the second frame buffer zone in next frame data write memory to be shown; The next frame data of being controlled in the second frame buffer zone by display controller show in the enterprising line output of display interface.
According to another embodiment of business datum display processing method, request is controlled in the first demonstration that applying unit sends in response to the user, carry out the operation of the first frame buffer zone in current frame data write memory to be shown, and the second demonstration control request sent in response to the user, carry out next frame data more to be shown and frame data identical in current frame data.The second demonstration that the user sends is controlled request and can be based on user interactive, for example, sliding mouse and changed menu bar, thus need to show the next frame data, triggered and carried out next frame data more to be shown and frame data identical in current frame data.
