Please refer to Fig. 2 A and 2B, it is the sequential chart of data display processing method according to an embodiment of the invention.What need explanation earlier is that it is that unit carries out the processing of video data that present embodiment adopts sweep trace.In simple terms, present display be adopt from left to right, order from top to bottom is shown in image data on the picture one by one and form overall image.And in this disposal route, each bar line from left to right just is called as a sweep trace.Therefore, video data will be made up of multiframe (frame) image data, and a frame image data can be divided into a plurality of scan-line datas, and each bar scan-line data is provided to as the employed data when showing of a sweep trace in the picture.Moreover, because the speed that enters of image data generally can be faster than being output the speed that is used as the usefulness that shows, so used two groups of double data traffic dynamic RAM (Double Data Rate Random Access Memory in the present embodiment; DDRRAM) as the picture working area that receives image data, and with four groups of static RAMs (StaticRandom Access Memory; The sweep trace working area of buffering usefulness during SRAM) for output.According to the present invention, can adopt the DDRRAM and the SRAM of same operation frequency, also can adopt operating frequency to be higher than the DDRRAM of SRAM, but in the latter case, the input port number of SRAM is wanted corresponding lifting, so that make time that image data spent when being read out from DDRRAM can be consistent with the time that same image data is written among the SRAM to be spent.
Next the meaning of each label among key drawing 2A and 2B and Fig. 4 A to 4C.What DDR1_W represented is that first group of DDRRAM write data, and the respective operations of box indicating thereafter in corresponding time section for example represented the scan-line data that writes.The representative of sign in the follow-up square frame be operation object why, for example: the 1st scan-line data in L1 (N-1) the expression N-1 frame image data; L3 (N) represents that then the data that write are the 3rd scan-line data in the N frame image data.Similarly mark also is applicable to DDR2_W (second group of DDRRAM write data), DDR1_R (sense data from first group of DDRRAM), DDR2_R (sense data from second group of DDRRAM) and SRAM1～4 (sense data from the 1st～4 group of SRAM).
Simplify and do not lose under the representational prerequisite making every effort to, present embodiment will be explained correlation technique content of the present invention with the situation that comprises eight scan-line datas in the frame image data.Present embodiment is to hocket with two groups of DDRRAM when receiving each frame image data, wherein scan-line data L1 (N-1), L3 (N-1), L5 (N-1), L7 (N-1), L1 (N), L3 (N), L5 (N) are written among first group of DDRRAM with L7 (N), and scan-line data L2 (N-1), L4 (N-1), L6 (N-1), L8 (N-1), L2 (N), L4 (N), L6 (N) then are written among second group of DDRRAM with L8 (N).
The identical time span of each tool of time section t1～t18 shown in the figure.As can be seen from the figure, in time section t1, scan-line data L1 (N-1) is written among first group of DDRRAM.Next, in next time section t2, scan-line data L2 (N-1) can be written among second group of DDRRAM.In proper order, eight scan-line datas of N-1 frame image data will be stored to respectively among two groups of DDRRAM according to this.
The detail operations content please merge with reference to Fig. 3, and it is the detailed sequential chart of data display processing method according to an embodiment of the invention.After scan-line data L1 (N-1) is written among first group of DDRRAM (DDR1_W1 as shown in Figure 3), this scan-line data L1 (N-1) can be read out (DDR1_R1 as shown in Figure 3) at time section t2, and is stored into the first group of SRAM the inside (S1_W1 as shown in Figure 3) in the sweep trace working area at the same time.First group of SRAM received scanline data L1 (N-1) in time section t2, and in time section t3 and t4 (input speed at this hypothesis image data is the twice of output speed) with scan-line data L1 (N-1) output usefulness (S1_R1 as shown in Figure 3) for demonstrations.Mode when the employed scan-line data L1 of odd number bar sweep trace (N-1), the L3 (N-1) in handling N-1 frame image data, L5 (N-1) and L7 (N-1) is roughly as implied above, all is just with the usefulness of its output for demonstration after the complete SRAM of the being written to the inside with scan-line data.The difference of each odd number bar sweep trace processing mode only is that employed SRAM is not quite similar, so in this processing mode of other odd number bar scan-line data of repetition of explanation not.
Please merge equally with reference to Fig. 2 A and 2B and Fig. 3.From another point of view, scan-line data L2 (N-1) is written into (DDR2_W1 as shown in Figure 3) in second group of DDRRAM in time section t2.Afterwards, scan-line data L2 (N-1) can be read out (DDR2_R1 as shown in Figure 3) in second group of DDRRAM in time section t5.The scan-line data L2 (N-1) that is read out in second group of DDRRAM can be written among time section t5 in another group (being made as second group herein) SRAM (S2_W1 as shown in Figure 3).Different with the processing mode of odd number bar scan-line data, scan-line data L2 (N-1) in being written into second group of SRAM in, also by from second group of SRAM, read out for demonstration with (S2_R1 as shown in Figure 3).Yet because the restriction of output speed, the running time of output scanning line data L2 (N-1) will be across two time section t5 and t6 from second group of SRAM.Mode when the employed scan-line data L2 of even number bar sweep trace (N-1), the L4 (N-1) in handling N-1 frame image data, L6 (N-1) and L8 (N-1) is roughly as implied above, all is beginning the usefulness of its output for demonstration in the complete SRAM of the being written to the inside with scan-line data.The difference of each even number bar sweep trace processing mode only is that employed SRAM is not quite similar, so in this processing mode of other even number bar scan-line data of repetition of explanation not.
Focusing on of the processing mode that present embodiment provided: because the DDRRAM operation that can not write simultaneously and read, so must be in the operation that DDRRAM is non-to read scan-line data when being in write state; Moreover, can be connected demonstration smoothly in order to make image frame, each the bar scan-line data in the same frame image data, must be connected with last the scan-line data that belongs to this frame image data and not overlap for when showing mutually in output.Therefore, according to above-mentioned principle, odd number bar scan-line data can just can provide next the bar scan-line data in the same frame image data to SRAM from DDRRAM after through two time sections after being provided to SRAM from DDRRAM; Relative, after even number bar scan-line data is provided to SRAM from DDRRAM, can next the bar scan-line data in the same frame image data be provided to SRAM from DDRRAM at next time section.Therefore, scan-line data L1 (N-1) is revealed in time section t3 and t4, scan-line data L2 (N-1) is revealed in time section t5 and t6, scan-line data L3 (N-1) is revealed in time section t7 and t8, scan-line data L4 (N-1) is revealed in time section t9 and t10, the rest may be inferred for all the other, to the last scan-line data L8 (N-1) is revealed in time section t17 and t18, has just finished the display operation of N-1 frame image data.
Please continue with reference to Fig. 2 A and 2B, present embodiment is for scan-line data L1 (N), the L2 (N) of N frame image data ... the processing mode of L8 (N) with to scan-line data L1 (N-1), the L2 (N-1) of N-1 frame image data ... the processing mode of L8 (N-1) has a little difference, its difference be in: the odd number bar scan-line data in N frame image data is stored among second group of DDRRAM, and even number bar scan-line data then is stored among first group of DDRRAM.But same, be stored in first group of scan-line data (as scan-line data L2 (N) and L4 (N) grade in an imperial examination even number bar scan-line data) in the DDRRAM, can after being written into the SRAM the inside fully, it just begin to carry out corresponding display operation; And be stored in second group of scan-line data (as scan-line data L1 (N) and L3 (N) grade in an imperial examination odd number bar scan-line data) in the DDRRAM, then when beginning to be written into SRAM, it promptly begins to carry out corresponding display operation.
Next please refer to Fig. 4 A to 4C, it is the sequential chart of the data display processing method of another embodiment of the present invention.In the present embodiment, identical for the processing mode of each frame image data with the embodiment shown in Fig. 2 A and the 2B, do not repeat them here.Yet this embodiment still has different expenditures with the embodiment shown in Fig. 2 A and the 2B, and these different expenditures are the time span difference of blank section (blanking period).Yet, as seen from the figure, in the display system of mode that invention is provided applicable to the blank section that possesses different time length.Though must be noted that all being in the present embodiment is the beginning scan-line data is write first group of DDRRAM, be also to be feasible mode at the beginning in fact scan-line data is write second group of DDRRAM.Various concrete variations can be learnt easily from aforesaid embodiment and the disclosed correlation principle of instructions, not repeat them here.
Can know by two embodiment shown in above-mentioned Fig. 2 A and 2B and Fig. 4 A to 4C, as long as the length of blank section (blanking period), as the time section t9 of Fig. 2 A and 2B and t18 or as time section t8～t12 of Fig. 4 A to 4C, certain specific integer multiple that can meet a scan-line data required time of DDRRAM read/write, so no matter scan-line data is from which group DDRRAM to begin to write, and image data processing mode provided by the present invention can suitably operate.
Yet the time span of the blank section of not all display system can both be the integer multiple of a scan-line data required time of DDRRAM read/write, so the time span of blank section needs suitably to adjust in some cases.Be the foundation that blank section is adjusted directly in one embodiment of the invention to handle the scan-line data required time.Please refer to Fig. 5, it is the original blank section of display system and the timing diagram that DDRRAM handles a scan-line data required time.As can be seen from Figure, the original blank section of display system is (from time point t
fTo time point t
r) approximately be equal to for one and half scan-line data processing time (DDR_SP).For adjusting original blank section is suitable length, can begin (time point tf) afterwards at original blank section, just begin to handle the next frame image data after the DDR_SP of the suitable number of forced counting.Thus, time point t
fWill be by suitably deferred backward and can requirement according to the invention.In another kind of mode, can utilize data stored in the complete output SRAM to adjust the blank section between two pictures whereby, the blank section between two pictures is adjusted to showing the integral multiple of each scan-line data required time.
In sum, by data display processing method provided by the present invention, only need use two groups of DDRRAM just can reach in the part in picture working area and make the whole normal effect of running that shows, need adopt storer more than three groups as the picture working area compared to prior art, obviously can reduce the use amount of memory element.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
