In present embodiment, this control device 210 comprises a display control module 220, a screen updates module 230, a buffer zone drafting module 240 and a display frame buffer zone 250.Wherein, the memory size of display frame buffer zone 250 for example is the half as much again of display 260 required pictures, that is this display frame buffer zone 250 can store display 260 image contents of half as much again, we are made of the picture of display 260 two 1/2 image frames at this, and wherein each image frame is made of two 1/2 image frames respectively in those image frames; This display frame buffer zone 250 can be divided into three unit in regular turn, is a first module 1, one second unit 2 and one the 3rd unit 3 in regular turn.Wherein the internal memory of each unit is that correspondence can store one 1/2 image frames.Because the display mode of display 260 all is from top to bottom to scan frame update one by one to form, thus the first half or the Lower Half of a display 260 pictures stored in each unit of present embodiment, that is 1/2 image frame or 1/2 image frame once on one.
In present embodiment, this display control module 220 can also comprise one and show index 222, a drafting index 224 and a field index 226.Wherein, show that index 222 desires to be shown in arbitrary unit in the display frame buffer zone 250 of display 260 pictures in order to indication, draw index 224 indications and desire to be drawn on arbitrary unit in the display frame buffer zone 250.Field index 226 is pointed to certain 1/2 image frame that desire is drawn, for example following 1/2 image frame of first image frame or last 1/2 image frame of the tenth image frame etc.
In present embodiment, after screen updates module 230 is accepted the demonstration control command of this display control module 220, to show that the content update of arbitrary unit in the indicated display frame buffer zone 250 of index 222 is to display 260, with first half image frame or the Lower Half image frame that upgrades this display 260.In view of the above, screen updates module 230 can be learnt the progress of these display 260 frame updatings.
Display control module 220 is sent a buffer zone rendering order in addition, and the arbitrary unit that makes 240 pairs of buffer zone drafting modules draw the indicated display frame buffer zone 250 of index 224 carries out the action that buffer zone is drawn; That is at this buffer zone drafting module 240 according to certain indicated 1/2 image frame content of field index 226, draw to the unit of drawing the indicated display frame buffer zone 250 of index 224.In this preferred embodiment, above-mentioned display control module 220 or buffer zone drafting module 240 can be carried out very complicated 3D processing action, to alleviate the calculated load of central processing unit.Or other assembly of display control program 200 finishes the rendered frame data processing earlier, only sees through buffer zone drafting module 240 the rendered frame data are copied to display frame buffer zone 250.The invention is not restricted to these three indexs and must be arranged in display control module 220, comprise these three indexs (show index 222, draw index 224 and field index 226) in only must this control device 210 to get final product.
Please refer to shown in Fig. 2 B, be a flow process synoptic diagram of Fig. 2 A display control program 200.At first set step 304, display control module 220 is drawn preparation with the content of first and second unit of drafting index 224 control display frame buffer zones 250, also be about to belong to that one the 1 image frame and one the 2 1/2 image frame content of Lower Half is drawn on respectively in above-mentioned first and second unit on one first image frame, then this is drawn index 224 and point to Unit the 3rd of drawing preparation as yet, and with these demonstration index 222 sensing first modules, and will represent the field index 226 that desire is drawn to point to one the 3 1/2 image frame.In this embodiment, the N+1 image frame tightly is connected in after the N frame, each image frame can be divided into two 1/2 image frames, the first half as above-mentioned first image frame is the one 1/2 image frame, the Lower Half of above-mentioned first image frame is the 2 1/2 image frame, the first half of above-mentioned second image frame is the 3 1/2 image frame etc., and the rest may be inferred.
Then open beginning step 308, this display control module 220 is carried out two sub-steps simultaneously: in a step display, this display control module 220 sends a screen updates order, make screen updates module 230 will show one of them location contents of index 222 display frame buffer zones 250 pointed, promptly finished 1/2 image frame content of drafting, upgrade the picture of aforementioned display device 260, that is the first half of frame update or Lower Half; In another plot step, this display control module 220 sends a buffer zone rendering order simultaneously, makes 240 pairs of one of them unit of drawing index 224 display frame buffer zones 250 pointed of buffer zone drafting module draw preparation.Then carry out step 312 and carry out a determining step, this display control module 220 judges whether above-mentioned step display is finished, if show that the picture first half has been finished in index 222 unit pointed or Lower Half is upgraded, then carry out step 320, otherwise carry out step 316.
In step 316, this display control module 220 judges whether above-mentioned plot step is finished, if above-mentioned two sub-steps are not all finished, then this flow process is got back to step 308, makes above-mentioned two sub-steps continue to carry out; If above-mentioned plot step is finished, then this flow process will be got back to step 312, and finishing up to frame updating begins to proceed step 320.
In step 320, these display control module 220 orders continue execution in step 324 after showing the next unit of index 222 sensings.State as preceding, three unit be with first, second, third, first, second unit etc. continues circulation in proper order.This display control module 220 will judge whether above-mentioned plot step is finished when carrying out step 324, if finished then execution in step 328, otherwise execution in step 332.If above-mentioned two sub-steps all executed finish, for example draw action faster than showing (one 1/2 image frame display update) action, then enter into step 328, these display control module 220 orders are drawn index 224 and are pointed to next unit, and after making field index 226 point to next 1/2 image frame, just get back to and open beginning step 308, to carry out the demonstration circulation of next 1/2 image frame.
In step 332, for example drawing action is slower than in showing (one 1/2 image frame display update) action, this display control module 220 makes screen updates module 230 will show that the content of index 222 unit pointed comes the picture of refresh display 260, that is carries out step display; In this simultaneously, above-mentioned buffer zone drafting module 240 still continues preparation is drawn in one of them unit of above-mentioned drafting index display frame buffer zone 250 pointed.Follow execution in step 336, display control module 220 judges whether above-mentioned steps 332 performed step displays are finished, if frame updating finishes, then carry out step 340, otherwise will continue carry out step 332, step display that order is carried out for the second time and plot step continue to carry out.
This display control module 220 will judge whether above-mentioned plot step is finished, and whether the unit of the drafting finished is promptly arranged when carrying out step 340, ready if these drafting index 224 unit pointed have been drawn, then carry out step 344, otherwise execution in step 348.In step 344, these display control module 220 orders show the next unit of index 222 sensings, draw index and point to next unit, and make this field index 226 refer to behind next 1/2 image frame, just get back to and open beginning step 308, carry out the demonstration circulation of next 1/2 image frame.In step 348, owing to there is not the unit of finishing drafting, after these display control module 220 orders show that index is pointed to a unit, just gets back to and open beginning step 308, carry out the step display that repeats a unit once more, and the still uncompleted plot step of order continues.
In present embodiment, the performed speed of above-mentioned step display and plot step will have influence on the flow process that Fig. 2 B marks.Generally speaking, drawing a whole image frame required time will so could show in real time less than the time of display update one whole image.Because the present invention tears an image frame for two halves open handles, so drawing one 1/2 image frame required times might be less than the time of half picture of display update, be a bit larger tham the time of upgrading half picture if draw one 1/2 image frame required times, but, also can reach the effect of real-time demonstration via suitable control less than the time of upgrading a whole image.
Please refer to Fig. 2 C, be a frame updating frequency diagram according to an embodiment of the invention.Situation shown in Fig. 2 C is the frame updating frequency diagram that is caused under the condition of one 1/2 image frame required times less than half image time of renewal when drawing.When being in one shown in Fig. 2 C constantly 430 the time, this demonstration index 222 has been pointed to second unit 2 that content has been completed, when being another previous time 425, the content of this Unit second 2 draws the drafting that index is carried out, promptly correspond to the Lower Half (3 times) of the three-picture frame that field index 226 grasped, in 226 the first half (on 4) of pointing to one the 4th image frame of 430 o'clock constantly field indexs, this draws 224 of indexs and points to the 3rd unit 3 in addition.
We correspond to Fig. 2 B part (step 308-312-320-324-328) with Fig. 2 C and describe at this, when being in above-mentioned moment 430, promptly begin the step 308 shown in the execution graph 2B, carry out a step display and a plot step simultaneously.In this step display, make screen updates module 230 will show the picture of the content update of second unit 2 that index 222 is pointed to display 260, also be about to the Lower Half that second location contents (i.e. three-picture frame Lower Half (3 times)) is updated to picture; In another plot step, make 240 pairs of buffer zone drafting modules draw index 224 the 3rd unit 3 pointed and draw, also be about to field index 226 the 4th image frame the first half (on 4) pointed and draw to Unit the 3rd.Then flow process proceeds to step 312, owing to be to draw one 1/2 image frame required times less than the situation of upgrading half image time shown in Fig. 2 C, in other words, above-mentioned plot step will be finished earlier than step display.In the example of this embodiment, the plot step when having finished if above-mentioned step display is not finished, then step 312 is judged step display and is not finished as yet, i.e. then execution in step 316.Thereafter, because of above-mentioned plot step is finished, so flow process returns step 312.In another example of this embodiment, if above-mentioned two steps are finished all when carrying out step 312, then then carry out step 320, will show index 222 by second unit 2 originally pointed then point to next unit, that is the 3rd unit 3.In next step 324, because of above-mentioned plot step is finished, so follow execution in step 328, make above-mentioned drafting index 224 transfer to point to next unit by the 3rd unit 3 originally pointed, that is first module 1, and make field index 226 the first half by the 4th image frame originally pointed, point to the latter half (4 times) of the 4th image frame.After finishing above step, sequential will be pushed and move to another moment 435, and above-mentioned flow process will return step 308.
Situation shown in Fig. 2 C with regard to the turnover rate of an entire frame, uses the frame display update rate of System and method for provided by the present invention identical with double buffering; Right the present invention but can utilize less display frame buffer zone to reach identical turnover rate, therefore reduces the consumption electronic products that internal memory is applicable to that area is compact.
Please refer to Fig. 2 D, be another frame updating frequency diagram according to an embodiment of the invention.Situation shown in Fig. 2 D is when drawing one 1/2 image frame required times greater than upgrading half image time but the frame updating frequency diagram that is caused under the condition less than the whole image time of renewal.When being in one shown in Fig. 2 D constantly 530 the time, this demonstration index 222 has been pointed to the first module 1 that content has been completed, when being previous time 510, the content of this first module 1 draws index indication first module 1, promptly correspond to the Lower Half (1 time) of field index 226 indicated one first frames, in the latter halfs (2 times) of one second frame of 226 sensings of 530 times field indexs constantly, this draws 224 of indexs and points to the 3rd unit 3.
We correspond to Fig. 2 B part (step 308-312-320-324-332-336-340-344) with Fig. 2 D and describe at this, when being in above-mentioned moment 530, promptly begin a step display and a plot step of the step 308 shown in the execution graph 2B.Screen updates module 230 will show the picture of the content update display 260 of the first module 1 that index 222 is pointed, and the first image frame Lower Half that also is about to first module 1 content is updated to the Lower Half of picture; In another plot step, make 240 pairs of above-mentioned buffer zone drafting modules draw index 224 the 3rd unit 3 pointed and draw, also be about to field index 226 second image frame the latter halfs pointed and draw to Unit the 3rd.
Upgrade 535 constantly of the round-robin moment 530 to one in the 3rd shown in Fig. 2 D, step 312 is all judged above-mentioned step display and is not finished as yet, promptly continues execution in step 316.Because the situation shown in Fig. 2 D, be when drawing a field required time, so in this example, step 316 will judge that above-mentioned plot step also fails to finish, so flow process is got back to former step 308 greater than upgrading half image time but less than the whole image time of renewal.
When being between the moment 535 to another moment 540, because of the step of above-mentioned demonstration first module 1 is finished, so step 312 will be followed execution in step 320 after finishing, order shows index 222 by the first module 1 of original sensing then point to second unit 2, and second unit 2 in be dissolved in the first half (on 2) of one second image frame that a previous time 520 drawn.In this example, when the plot step of judging above-mentioned drafting the 3rd unit 3 when an inferior step 324 has been finished, then will then carry out step 328, otherwise execution in step 332.Because drafting time this moment is longer than display refresh time, do not finish as yet so judge the plot step of drafting the 3rd unit 3 before the moment 540 in step 324, therefore enter into step 332 and carry out step display and still draw preliminary work; In other words, military order screen updates module 230 will show that the content update of second unit 2 that index 222 is pointed is in the picture of display 260, the second image frame first half (on 2) that also is about to Unit second 2 contents is updated to the first half of picture, in the plot step of still field index 226 second image frame the latter halfs pointed being drawn in 540 o'clock constantly to the 3rd unit 3.Then in an inferior step 336, judge once again whether step display is finished, because the situation shown in Fig. 2 D, be when drawing a field required time greater than half image time of renewal but less than the whole image time of renewal, so in this example, when the step display of this step 336 has been finished, then the step of carrying out 340 will be judged plot step and also finish.In view of the above, to continue execution in step 344, between the moment 540 and 545 as shown in Fig. 2 D, to show that index 222 turns to the 3rd unit 3 by original second unit 2 pointed, turn to first module 1 with drawing index 224 by original the 3rd unit 3 pointed, and the last field (on 3) that field index 226 is pointed to a three-picture frame by the second image frame Lower Half (2 times).
The picture that the present invention does not limit display cuts into two 1/2 image frames and constitutes, we also can be constituted a picture by a plurality of image frame, certainly the unit of stored picture frame also is not limited to 3, when the image frame render speed faster than showing (image frame renewal) speed, the number of unit that we can control to the stored picture frame near or be less than the image frame number of a picture, otherwise when being slower than demonstration (image frame renewal) speed as if the image frame render speed, also can be reduced to below the capacity twice originally wanting the unit of the above stored picture frame of picture capacity twice or twice.Therefore, no matter embedded system (embeddedsystem) or system-on-a-chip (system on chip) adopt apparatus and method provided by the present invention, the consumption that then can reduce hardware cost by the minimizing of internal memory and reduce electric power.
