Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It will be appreciated that to enable the display of screen data by the screen, the screen is typically in direct signal communication with the processor. For example, taking an electronic device as an example, during a starting process of the electronic device or a process of switching from a screen-off state to a screen-on working state, the processor sends a control signal to the screen through the signal connection channel, and the screen sends a feedback signal to the processor. Upon receiving the feedback signal, the processor sends a data signal (screen data) to a driving circuit of the screen. Meanwhile, the driving circuit of the screen converts the received data signals into driving signals of the screen, and drives the screen to display data information, so that display is completed.
with the development of display control technology, in order to flexibly adapt to various display modes of a device, a plurality of processors are configured in a related display system to control one screen respectively. For example, as shown in fig. 1, the electronic device 100 shown in fig. 1 includes a first processor 110 and a second processor 120, and a screen 200, wherein the first processor 110 and the second processor 120 can respectively control the screen 200. It should be noted that the number of processors in the embodiment of the present application may be more, and is not limited to the two processors in fig. 1.
In the process of controlling a screen by a plurality of processors respectively, in order to ensure the consistency and the synchronism of the display of the screen data, when the control authority is transferred from the previous processor to the next processor, the previous processor synchronizes the screen data displayed by the current control screen to the next processor. In the research, the inventor finds that as the screen of the electronic device is larger and larger, more and more data need to be synchronized in the process of synchronizing the screen data. In the related screen data synchronization process, the screen data is composed of the pixel values of the pixels at each position of the screen, and in the specific data synchronization process, the pixel values of the pixels at each position of the screen are synchronized from one processor to another processor at one time, so that the synchronized data amount at one time is large. Taking 1920x1080 resolution 3 bytes per pixel as an example, 6.2MB of data would need to be synchronized between the two processors in an amount sufficient to cause frame loss when the processors are switched.
Therefore, the inventor proposes a screen data processing method, a device and an electronic device in the present application that can improve the above-mentioned problems. Therefore, by the method, in the process of switching the processors, because the second processor which controls the screen synchronizes part of the screen data to the first processor before switching in advance, when the processors are actually switched, the second processor can enable the first processor to control the screen to display based on the generated complete screen data only by synchronizing part of the screen data in the complete screen data, so that the data volume of the synchronized data in the process of switching the processors and the time consumed by synchronization are reduced, and the negative effects of frame loss and the like caused by single synchronization of a large amount of screen data are eliminated.
Embodiments of the present application will be described in detail below with reference to the accompanying drawings.
Referring to fig. 2, a screen data processing method provided in an embodiment of the present application is applied to an electronic device, where the electronic device includes a screen and a plurality of processors, and each processor is configured to control the screen individually, and the method includes:
Step S110: the method comprises the steps that a first processor obtains first screen data which are synchronized when a second processor hands over the authority for controlling the screen to the first processor, the first screen data are partial data in complete screen data, the first processor is a processor used for currently controlling the screen, and the second processor is a former processor used for controlling the screen.
It should be noted that, in the related screen data synchronization process, screen data synchronization is performed in units of pixels. In this manner, the last processor with control authority transmits data describing the pixel values, e.g., RGB values, displayed by each pixel point in the process of synchronizing the screen data to the next processor. In the embodiment of the application, the electronic device may perform modeling recognition on the content of the screen data in advance, and further classify the content displayed on the screen, for example, the content may be classified into clock data, electric quantity data, date data, and the like.
Further, some attributes, such as display position, size, display content, display subject, etc., may be configured for each classified data. It is understood that the display position refers to where the data of the category is displayed on the screen, the size is the size of the data of the category, and the display content refers to the content to be displayed to the user. For example, for the clock-like screen data, the content to be presented to the user is time, for example, the current time is 12 o' clock, and the display content is "12". For the clock-type screen data, the content to be displayed to the user is the electric quantity, for example, the current electric quantity is 98%, and the display content is "98%". Further, the display theme therein represents at least one of a font style, a font size, an icon style, and a background picture.
Based on the above, in the present embodiment, there may be at least two implementations of the first screen data. In one mode, the first screen data is data representing the display content in the complete screen data. For example, the first screen data includes the aforementioned "12" representing the current time, and may also include "98%" representing the current amount of power. Then in this manner the second screen data is the aforementioned attribute.
Alternatively, the first screen data is pixel data of an area of the full screen data where contents are automatically and dynamically changed. The area in which the content is automatically and dynamically changed may be the area in which the time is displayed, the area in which the power is displayed, or the area in which the push information is displayed. Accordingly, in this manner, the screen data of the area other than the area of the content is automatically dynamically changed to the second screen data.
it should be noted that the complete screen data is data representing the displayed content of each pixel point of the screen.
it is understood that, besides data of time, power and the like which dynamically change, other contents in the screen of the electronic device are not changed dynamically. For example, in a desktop scenario, icons on the desktop, descriptive text next to the icons, and the background of the entire desktop are typically statically present. The icon on the desktop and the description text beside the icon are usually changed after the system or the application program is updated. Similarly, the background to the desktop may be changed after the user reconfigures. In this manner, the electronic device may divide the display area of the screen in advance, so that each of the control units therein may recognize the area in which the content is automatically and dynamically changed and the area other than the area in which the content is automatically and dynamically changed, and further use screen data corresponding to the area in which the content is automatically and dynamically changed as the first screen data.
as a distinguishing method, the electronic device may establish a coordinate system with a position of a certain pixel point of the screen as an origin of coordinates, so as to divide the screen into regions by coordinates, and further distinguish a region in which the content is automatically and dynamically changed from a region other than the region in which the content is automatically and dynamically changed by the coordinates.
As indicated in the foregoing, the first processor is the processor that is currently configured to have the authority to control the screen. In order to facilitate each control unit to identify whether it is already a control unit having control authority, as a way, one control unit may add data about identifying authority transfer to the screen data in the process of synchronizing the screen data to the other control units. Optionally, the screen data synchronized in the embodiment of the present application may include two parts, one part is a data header, and the other part is a data body. The data header may store some configuration information, such as an identifier of a sending processor of the currently synchronized screen data, an identifier of a receiving processor of the currently synchronized screen data, whether to perform the permission transfer, and the like. And the screen data to be synchronized can be stored in the data body. In this way, the processor can determine whether the currently synchronized screen data is the aforementioned first screen data or the aforementioned second screen data by the content in the data header while receiving the screen data, and can know whether the transfer of the control authority has occurred currently, specifically to which processor.
Furthermore, it should be noted that each processor has a corresponding storage area for storing data. Then, for one processor to synchronize the screen data to another processor, it is understood that one particular processor transfers the screen data in its corresponding storage area to the storage area of the other processor's corresponding storage data.
Step S120: and acquiring second screen data synchronized in advance by the second processor before the permission handover, wherein the second screen data is partial data in the complete screen data.
It is understood that in order to reduce the data amount of screen data synchronized at the time of control authority transfer. The processor with the control authority synchronizes part of the screen data in the current screen data to the second processor after the data synchronization condition is met, that is, the processor with the control authority can synchronize the second screen data to other processors after the data synchronization condition is met. The synchronization here may be understood as that the processor currently having the control authority transfers the second screen data from the storage area corresponding to the processor to the storage areas corresponding to the other processors. In this manner, the first processor acquires the second screen data pre-synchronized by the second processor before the authority transfer, which can be understood as reading the second screen data pre-synchronized by the second processor before the authority transfer from the storage area corresponding to the first processor.
Step S130: generating complete screen data based on the first screen data and the second screen data.
It should be noted that in the embodiments, there are various ways to implement the first screen data and the second screen data, and then the corresponding first processor performs the process of generating the complete screen data based on the specific implementation of the first screen data and the second screen data.
optionally, in a manner that the first screen data is data representing the display content in the complete screen data, and the second screen data is the attribute, the data synchronized by the second processor in the process of synchronizing the data with the first processor is generated based on the content object. In this manner, the first processor determines the specific content of the displayed content object according to the first screen data and generates the display form of the specific content according to the second screen data in the process of generating the complete screen data. For example, if the first screen data received by the first processor includes time (content object) with specific content of 12 and the second screen data received in advance includes identification data regarding the analog clock and identification data regarding the background picture as pure black, then in this case, the first processor generates a background picture with black and displays an analog clock on the background picture, and the analog clock displays full screen data with time of 12. For another example, if the first screen data received by the first processor includes 98% of the specific content of the electric quantity (content object), and the second screen data received in advance includes the identification data about the analog battery and the identification data about the background picture as pure black, then in this case, the first processor generates a background picture as black, and displays an analog battery on the background picture, and the analog battery displays the complete screen data with the electric quantity of 98%.
It should be noted that the identification data is data for identifying the content object. For example, if the transmitted identification data is time _1, it can be identified as a mode clock, and for example, if the transmitted identification data is time _2, it can be identified as a digital clock. The data amount of the synchronized data can be reduced by transmitting the identification data instead of directly synchronizing the pixel data of the content identified thereby.
Optionally, in a manner that the first screen data is pixel data of an area in the complete screen data, where the content is to be automatically and dynamically changed, and the screen data of an area outside the area, where the content is to be automatically and dynamically changed, is the second screen data, the data synchronized between the control units is direct pixel data. Also, it is understood that the second processor performs in a coordinate manner in generating the first screen data and the second screen data. Then, in the process of generating the complete screen data, the first processor splices the pixel data according to the respective corresponding coordinate regions of the first screen data and the second screen data, so as to generate the complete screen data. For example, as shown in FIG. 3, in the screen content shown in FIG. 3, area 99 may be used to display time, power, push information, etc., while area 98 may be used to display a desktop or display an interface for a particular application. It will be appreciated that the time, power, and push information may be dynamically changing content, and the desktop or interface of a particular application may be relatively static content, then the second processor may determine region 99 as the region where the content is to be automatically dynamically changed and region 98 as a region other than the region where the content is to be automatically dynamically changed. It can be understood that, compared to the case where the pixel data corresponding to the area 99 and the area 98 are synchronized only when the control authority is transferred, and the data of the area 98 is synchronized in advance, the pixel data of the area 99 is only synchronized when the control authority is transferred, and the amount of data of the synchronization data required when the control authority is switched can be reduced.
In addition, other area division methods may be used in addition to the area division method shown in fig. 3. For example, as shown in fig. 4, if a region 97 is provided in the region 98 for displaying a time control, the region 97 may be determined as a region in which the content is automatically and dynamically changed, in this manner, the first screen data includes pixel data of the region 99 and the region 97, and the second screen data includes pixel data of the region 96.
Step S140: displaying the full screen data based on controlling the screen.
According to the screen data processing method, under the condition that the electronic equipment comprises a screen and a plurality of processors, each processor is used for independently controlling the screen, a first processor used for currently controlling the screen acquires first screen data synchronized by a second processor used for controlling the screen, the first screen data is partial data in complete screen data, second screen data synchronized by the second processor in advance before permission transfer is acquired, the second screen data is partial data in the complete screen data, and complete screen data is generated based on the first screen data and the second screen data; and controlling the screen to display based on the generated complete screen data.
Therefore, by the method, in the process of switching the processors, because the second processor which controls the screen synchronizes part of the screen data to the first processor before switching in advance, when the processors are actually switched, the second processor can enable the first processor to control the screen to display based on the generated complete screen data only by synchronizing part of the screen data in the complete screen data, so that the data volume of the synchronized data in the process of switching the processors and the time consumed by synchronization are reduced, and the negative effects of frame loss and the like caused by single synchronization of a large amount of screen data are eliminated.
Referring to fig. 5, a screen data processing method provided in an embodiment of the present application is applied to an electronic device, where the electronic device includes a screen and a plurality of processors, and each processor is configured to control the screen individually, and the method includes:
Step S210: the method comprises the steps that a first processor obtains first screen data which are synchronized when a second processor hands over the authority for controlling the screen to the first processor, the first screen data are partial data in complete screen data, the first processor is a processor used for currently controlling the screen, and the second processor is a former processor used for controlling the screen.
Step S220: and acquiring second screen data synchronized in advance by the second processor before the permission handover, wherein the second screen data is partial data in the complete screen data.
step S230: generating complete screen data based on the first screen data and the second screen data.
step S240: and controlling the screen to display based on the generated complete screen data.
Step S250: and after the first processor detects that a data synchronization condition is met, synchronizing second screen data in the screen data corresponding to the current display scene to the second processor, wherein the first screen data represent the display content of the current display scene, and the second screen data represent the display theme of the current display scene.
it should be noted that, in the display theme selection scene, the user may frequently switch the display theme so as to select a display theme required by the user. Based on the foregoing, after the display theme is updated, the processor currently having the authority to control the screen synchronizes the display theme selected by the user as the second screen data to the second processor, and the latest synchronized second screen data covers the last synchronized second screen data, so that if the continuous synchronization of the second screen data for multiple times does not contribute to the final generated screen data, but is only covered by the second screen data received later, a great waste of resources is caused.
In order to solve the problem, as a mode, after the first processor detects that a data synchronization condition is satisfied, the step of synchronizing the second screen data in the screen data corresponding to the current display scene to the second processor includes:
when the first processor detects that a data synchronization condition is met, acquiring target data, wherein the target data is partial data in second screen data in screen data corresponding to a current display scene; synchronizing the target data to the second processor and starting to detect whether a continuous transmission condition is met; and if the condition is met, synchronizing data except the target data in second screen data in the screen data corresponding to the current display scene to the second processor.
Optionally, the continuous transmission condition includes: and not detecting that the data synchronization condition is met again within a specified time after the target data is synchronized to the second processor. It can be understood that if it is not detected again that the data synchronization condition is satisfied within the specified time length, it may be determined that the user has determined the display theme required by the user, and the display theme is not switched again within a short time. Then in this case the first processor may synchronize the remaining not yet synchronized data of the data that needs to be pre-synchronized to said second processor.
Optionally, the second screen data includes font style data, font size data, icon style data, and background picture data, and the target data is data with the smallest data size among the font style data, the font size data, the icon style data, and the background picture data. It will be appreciated that synchronizing the least amount of data ahead of time may further reduce wasted data transmission resources. For example, the font style data, font size data, icon style data, and background picture data included in the second screen data are 100k, 110k, 500k, and 1MB in this order. Then the target data in this case can be determined as the font style data of 100K, because if the next selected display theme is still switched, the wasted transmission resources are the resources consumed for transmitting the 100K, whereas if the next selected display theme is directly synchronized to the second processor, the data of 100K, 110K, 500K and 1MB are wasted (i.e. the transmission resources of 1MB +500K +110K +100K 1734KB are wasted).
By one approach, the data synchronization condition includes: after the electronic equipment is started; or when a display theme of the electronic device is changed, wherein the display theme includes at least one of a font style, a font size, an icon style, and a background picture.
It should be noted that, in the multiple processors of the electronic device provided in the embodiments of the present application, the data processing capabilities of different processors may be different. The data processing capability here is understood to be the amount of data or the number of threads that can be processed per unit time. For example, if the first processor is a general-purpose processor and the second processor is a low-power processor, the data processing capability of the first processor is stronger than that of the second processor. Then, as an adaptation, when the general-purpose processor is used as the first processor, the generated first screen data synchronized to other processors (e.g., low power processors) is pixel data of an area of the complete screen data where the content is to be automatically dynamically changed. If the general-purpose processor is used as the second processor, the generated first screen data synchronized to other processors (for example, the general-purpose processor) is data representing the display content in the complete screen data, so that the data processing capability of the processor for controlling the screen authority is adapted to the amount of data to be processed in the process of switching the general-purpose processor and the low-power processor, thereby improving the overall operation effect of the electronic device.
it can be understood that, in this way that the first screen data is the data representing the display content in the complete screen data, the synchronized data is the identification data identifying the display content and the display subject, and the processor receiving the identification data identifying the display content and the display subject needs to generate the pixel data first before generating the complete screen data, so the data processing capability requirement of the processor generating the complete screen data based on the identification data identifying the display content and the display subject is relatively high. In the mode that the first screen data is pixel data of an area in the complete screen data, where the content is automatically and dynamically changed, the operation required by the processor for acquiring the control screen authority is only the splicing of the pixel data, and the data processing capability of the processor is relatively low. Therefore, the data processing capacity of the processor obtaining the authority to control the screen can be adapted to the amount of data required to be processed by the configuration mode.
according to the screen data processing method, in the process of switching the processors, because the second processor which controls the screen synchronizes partial screen data to the first processor before switching in advance, when the processors are actually switched, the second processor can enable the first processor to control the screen to display based on the generated complete screen data only by synchronizing partial screen data in the complete screen data, so that the data volume of the synchronized data and the time consumed by synchronization in the switching process of the processors are reduced, and negative effects such as frame loss and the like caused by single synchronization of a large amount of screen data are eliminated.
Furthermore, in the screen data processing method provided in this embodiment, the first processor may also synchronize the second screen data with the second processor, so that the second screen data stored in other processors may be updated in real time, and after the first processor hands over the control right to the screen to the second processor, the second processor may also generate the screen data quickly.
Referring to fig. 6, a screen data processing method provided in an embodiment of the present application is applied to an electronic device, where the electronic device includes a screen and a plurality of processors, and each processor is configured to control the screen individually, and the method includes:
Step S310: and when the electronic equipment enters a low-power-consumption mode, the second processor transfers the authority for controlling the screen to the first processor, and synchronizes first screen data to the first processor.
It should be noted that, in this embodiment, the entering of the low power consumption mode by the electronic device may be entering the low power consumption mode based on an event of automatic configuration, for example, when it is detected that the electric quantity is lower than a specified value, the entering of the low power consumption mode is triggered, or when it is detected that no application program other than the system program runs in the electronic device, the entering of the low power consumption mode is triggered. Further, the low power consumption mode may also be entered in response to a manual operation by the user.
The low power consumption mode may be a mode in which some functions are turned off (for example, a network access function is turned off), or may also be a sleep mode. Wherein in the sleep mode, the electronic device may display only the power and the time in the screen.
step S320: the method comprises the steps that a first processor obtains first screen data which are synchronized when a second processor hands over the authority for controlling the screen to the first processor, the first screen data are partial data in complete screen data, the first processor is a processor used for currently controlling the screen, and the second processor is a former processor used for controlling the screen.
Step S330: and acquiring second screen data synchronized in advance by the second processor before the permission handover, wherein the second screen data is partial data in the complete screen data.
step S340: generating complete screen data based on the first screen data and the second screen data;
Step S350: and controlling the screen to display based on the generated complete screen data.
According to the screen data processing method, in the process of switching the processors, because the second processor which controls the screen synchronizes part of the screen data to the first processor before switching in advance, when the electronic equipment enters the low power consumption mode to execute the actual switching of the processors, the second processor can enable the first processor to control the screen to display based on the generated complete screen data only by synchronizing part of the screen data in the complete screen data, so that the data volume of the synchronized data and the time consumed by synchronization in the switching process of the processors are reduced, and the negative effects of frame loss and the like caused by single synchronization of a large amount of screen data are eliminated.

Step S410: the first processor monitors screen control permissions.
Step S420: and if the first processor monitors that the authority for controlling the screen is transferred from the second processor to the first processor, receiving screen content description information synchronized by the second processor, wherein the screen content description information represents the content to be displayed by the screen.
It is understood that the screen content description information herein is description information generated based on the displayed content object, and is different from the specific pixel value of each pixel point. For example, for the example of a display clock, the content of the corresponding screen data in the form of the screen content description information may be a clock displaying a specified pattern at a specified position, and the corresponding screen data in the form of a pixel value may be a pixel value of each specific pixel point of the clock.
Step S430: the first processor controls the screen to display based on the screen content description information.
In one way, the screen content description information may be full screen data including display content and a display theme for controlling a scene displayed on the screen when the second processor hands over the right.
Alternatively, the screen content description information may be partial data in the full screen data, such as the aforementioned first screen data. In this way, the second screen data included in the complete screen data is pre-synchronized by the second processor to the first processor before the permission handover, so that after the first processor acquires the first screen data, the complete screen data can be calculated based on the pre-synchronized second screen data, thereby controlling the screen to display the complete screen data.
