Detailed Description
In order to make the objects, features and advantages of the present application more obvious and understandable, 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 apparent that the described embodiments are only a part of the embodiments of the present application, and not all 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.
In the description herein, reference to the description of the term "one embodiment," "some embodiments," "an example," "a specific example," or "some examples," etc., means that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the application. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples. Furthermore, various embodiments or examples and features of different embodiments or examples described in this specification can be combined and combined by one skilled in the art without contradiction.
Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or to implicitly indicate the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.
In the present application, the on-chip integrated system is a system running on a system-on-chip, and the system-on-chip includes components such as a computing unit (core), a memory, a power supply controller, a clock controller, an interrupt controller, etc., and can execute a set of complete system functions in cooperation with embedded software.
Generally, an integrated system on chip establishes a set of system functions focused on a certain target based on components on a system-on-chip, including: an Operating System (OS), and a series of applications running on top of the OS that focus on a certain target.
For a large-scale integrated system such as an intelligent cockpit system or an intelligent home system, a plurality of on-chip integrated systems may need to be operated to respectively achieve different targets.
For example, for an intelligent cabin system, it may be necessary to separately: on the first system level chip, a first on-chip integrated system for performing security detection and displaying dashboard data is constructed and operated; on the second system level chip, a second on-chip integrated system for operating various components (such as a vehicle window, a left rear-view mirror and a right rear-view mirror) and displaying a central control interface is constructed and operated; on the second system-on-chip, a third integrated system-on-chip for implementing entertainment functions, playing multimedia, running entertainment applications, etc. is constructed and run.
The integrated system on chip is connected with the corresponding display screens based on the respective system level chips respectively, and the respective display screens are independently controlled. For example, the first on-chip integrated system controls a dashboard screen connected to the first system-on-chip to display dashboard data; the second on-chip integrated system controls a central control screen connected on the second system level chip to display a central control interface, and if the second system level chip is also connected with a left rear-view mirror screen and a right rear-view mirror screen, the left rear-view mirror screen and the right rear-view mirror screen are also controlled to display corresponding information; the third on-chip integrated system controls an In-Vehicle information (IVI) display screen connected to the third system-level chip, plays multimedia, runs entertainment applications, and the like.
In the large-scale integrated system composed of the plurality of on-chip integrated systems, it is difficult to play the same target resource, such as the boot animation or the shutdown animation, synchronously. Firstly, each on-chip integrated system needs to download the target resource to a local memory; and then, the on-chip integrated systems respectively control the display screens to play. In this process, the integrated systems on the chips may be in a state where communication is impossible (for example, the system is not started before the system is started or the system is stopped after the system is shut down), so that it is difficult to perform synchronous playing, and therefore, a situation occurs in which the first integrated system on the chip may have already played the target resource, and the second integrated system on the chip has just downloaded the target resource, and the playing is not yet achieved.
In order to solve the above problem, the present application provides a multi-screen display control method, which is applied to a first subsystem in a multi-core heterogeneous on-chip integrated system.
The multi-core heterogeneous on-chip integrated system refers to a large-scale integrated system running on a super system-level chip. The super system-on-chip refers to a device including a plurality of computing units (multi-core), a plurality of allocable memory blocks, a plurality of power controllers, a plurality of clock controllers, a plurality of interrupt controllers, and the like. The components described above may be divided into multiple hardware domains, each containing specific system resources required by a particular system, such as one or more compute units (cores), clock controllers, interrupt controllers, and available memory space, among others. System resources in different hardware domains are isolated from each other. Based on each hardware domain, a separate operating system may be installed, building and running subsystems that achieve specific goals. Interaction and cooperation among the subsystems can be realized through inter-core communication.
Thus, the multi-core heterogeneous on-chip integrated system can realize all functions of a large-scale integrated system through a plurality of specific target subsystems running on a super system-level chip.
Fig. 1 illustrates a multi-core heterogeneous integrated system on a chip 10 on which a multi-screen display control method is implemented according to an embodiment of the present application.
As shown in fig. 1, the multi-core heterogeneous integrated system on a chip 10 runs on a super system-on-chip, which at least has N first type cores, M second type cores, and other components, and is connected to a plurality of display screens through a plurality of display interfaces: a first display screen 1011, a second display screen 1012, a third display screen 1021, and a fourth display screen 1022.
The multi-core heterogeneous integrated system on chip 10 builds and operates at least two subsystems based on the super system-level chip: a first subsystem 101 and a second subsystem 102. Wherein the first subsystem 101 displays the respective outputs using the first display screen 1011 and the second display screen 1012; the second subsystem 102 displays the corresponding output using the third display 1021 and the fourth display 1022.
To this end, the N first type cores of the super system-on-chip and other required components may be divided into a first hardware domain, and a first type Operating System (OS) may be installed based on the first hardware domain to form a first subsystem 101; the M second-type cores of the super system-on-chip and the corresponding hardware resources are divided into a second hardware domain, and a second-type OS is installed based on the second hardware domain to form a second subsystem 102.
The first subsystem 101 and the second subsystem 102 may interact and cooperate through inter-core communication. Inter-core communication may be through communication modules on the super system-on-chip, such as mailboxes (mailboxes) and shared memory, to send commands and exchange data.
For a plurality of display screens connected on the super system level chip, a display interface connected with each display screen can be divided into a certain hardware domain, a subsystem based on the hardware domain can generate display information, the display information is sent to the display screens through the display interfaces, and the corresponding display screens are directly controlled and used.
The subsystems based on the hardware domain can also acquire output information which is required to be displayed by other subsystems through inter-core communication, generate display information according to the output information which is required to be displayed by other subsystems, and send the display information to a display screen through a display interface. In other words, the subsystems in the multi-core heterogeneous on-chip integrated system can send instructions and output information to other subsystems through inter-core communication, and indirectly control and use a certain display screen through other subsystems.
Therefore, the display interface for connecting the display screen can be more flexibly distributed in the hardware domain.
For example, a display interface with a first display screen 1011 and a second display screen 1012 connected thereto may be divided into a first hardware domain, directly controlled and used by the first subsystem 101; the display interface to which the third display 1021 and the fourth display 1022 are connected is divided into a second hardware domain, which is directly controlled and used by the second subsystem 102.
Or the display interfaces connected with the display screens can be divided into a first hardware domain, and a display screen centralized management module is realized in the first subsystem 101, and each subsystem indirectly controls and uses the corresponding display screen through the display screen centralized management module. Specifically, the first subsystem 101 may indirectly control and use the first display screen 1011 or the second display screen 1012 through the display screen centralized management module; the second subsystem 102 may indirectly control and use the third display 1021 and the fourth display 1022 through the display centralized management module.
In addition, each subsystem in the multi-core heterogeneous on-chip integrated system can send instructions and output information to other subsystems through inter-core communication, and indirectly control and use a certain display screen through other subsystems, so that the possibility of centrally controlling a plurality of display screens used by each subsystem through a certain subsystem is created, and the multi-screen display control method provided by the application is realized.
Assuming that, in the implementation of the present application based on the multi-core heterogeneous integrated system on a chip 10 shown in fig. 1, the first subsystem 101 centrally controls a plurality of display screens used by each subsystem, the multi-screen display control method of the present application can be implemented by the flow shown in fig. 2. Referring to fig. 2, the method includes:
operation S210, acquiring a target resource to be displayed;
the target resource to be displayed may be a text, a picture, an animation, or the like.
Operation S220, controlling at least two display screens connected to the multi-core heterogeneous on-chip integrated system 10 to synchronously display the target resource on the at least two display screens;
wherein the at least two display screens comprise display screens used by the second subsystem 102 of the multi-core heterogeneous on-chip integrated system.
The at least two display screens connected to the multi-core heterogeneous on-chip integrated system 10 refer to at least two display screens connected through a display interface on a super system chip on which the multi-core heterogeneous on-chip integrated system 10 operates.
When the first subsystem 101 controls at least two display screens connected to the multi-core heterogeneous on-chip integrated system 10, corresponding operations may be executed according to a hardware domain where the display screens are located:
if the display interface to which the first display screen 1011 and the second display screen 1012 are connected is divided into a first hardware domain and the display interface to which the third display screen 1021 and the fourth display screen 1022 are connected is divided into a second hardware domain, the first subsystem 101 may directly control the first display screen 1011 and the second display screen 1012 and indirectly control the third display screen 1021 and the fourth display screen 1022 through inter-core communication with the second subsystem 102.
If the display interfaces connected to the display screens are all divided into a first hardware domain, and the display screens are centrally controlled by the display screen centralized management module in the first subsystem 101, the first subsystem 101 may directly control the first display screen 1011, the second display screen 1012, the third display screen 1021, and the fourth display screen 1022 through the centralized management module.
In the present application, display refers to a broad display, and includes not only display of static resources such as text and images, but also playback of dynamic resources such as animation and video, and projection of static resources or dynamic resources.
In the application, synchronous display mainly means that a plurality of display screens start to display at almost the same time and keep the display contents synchronous and consistent during display; in the application, the synchronous display does not include ending the display at the same time, and the plurality of display screens can end the display at different times according to needs.
Since the target resource is acquired by the first subsystem 101, the display screen used by each subsystem is controlled by the first subsystem 101. Therefore, the target resource only needs to be downloaded once and then can be simultaneously sent to the display screens used by the subsystems, and even under the condition that the third display screen 1021 and the fourth display screen 1022 are indirectly controlled by the second subsystem 102 through inter-core communication, the delay is very small and even is not easy to be detected by naked eyes, so that the synchronization of display in the display screens is easier to realize.
It should be noted that, in the embodiment of the present application, only the first subsystem 101 and the second subsystem 102 in the multi-core heterogeneous integrated-on-chip system 10 are shown in fig. 1, and in practical applications, the multi-core heterogeneous integrated-on-chip system may include more than two subsystems, and the first subsystem 101 may be used to control all display screens used by all subsystems in the multi-core heterogeneous integrated-on-chip system 10, or may be used to control only a part of display screens used by a part of subsystems of the multi-core heterogeneous integrated-on-chip system 10.
In addition, in other embodiments, the number of display screens used by each subsystem is not limited, and may be 0 or 1 or more, including the first subsystem for controlling the display screens used by the subsystems.
Fig. 3 to 6 show another embodiment of the present application. The embodiment realizes an intelligent cockpit system based on a multi-core heterogeneous on-chip integrated system.
As shown in fig. 3, the smart cabin system is provided with a plurality of display screens, for example, a left rear view mirror 3011, a right rear view mirror 3012, a streaming media (HUD) 3021, a dashboard 3022, an IVI main screen 3031, and an IVI sub-screen 3032.
A plurality of computing units are arranged in a super system-on-chip based on the intelligent cockpit system, X cores and other required components are divided into a first hardware domain, an operating system RTOS is installed based on the first hardware domain, and a left rear-view mirror application 3014 and a display screen centralized management module 3013 are deployed on the RTOS to form a left rear-view mirror subsystem 301 and a right rear-view mirror subsystem 301; dividing Y cores and other required components into a second hardware domain, installing an operating system Linux based on the second hardware domain, and deploying a streaming media application 3023 and a dashboard application 3024 on the Linux to form a dashboard subsystem 302; the Z cores and other required components are divided into a third hardware domain, an operating system Android is installed based on the third hardware domain, and a multimedia playing application 3033 is deployed on the Android to form an entertainment subsystem 303.
The display interfaces connected with the display screens in the intelligent cabin are divided into a first hardware domain, the left rearview mirror subsystem 301 and the right rearview mirror subsystem 301 are used as a first subsystem, and the display screens are managed and controlled by the display screen centralized management module 3013 in the left rearview mirror subsystem 301 and the right rearview mirror subsystem 301. Each subsystem can indirectly control and use the corresponding display screen through the display screen centralized management module 3013.
For example, the left and right rearview mirror applications 3014 in the left and right rearview mirror subsystems 301 indirectly control and use the left and right rearview mirrors 3011 and 3012 to output prompt information given in a specific scene through the display screen centralized management module 3013; the stream media application 3023 in the dashboard subsystem 302 indirectly controls and uses the stream media 3021 to project important driving information such as speed per hour, navigation, and the like onto a windshield in front of the driver through the display screen centralized management module 3013, so that the driver can see the important driving information such as speed per hour, navigation, and the like without lowering or turning his head as much as possible; the dashboard application 3024 in the dashboard subsystem 302 indirectly controls and uses the dashboard 3022 to display dashboard data such as fuel volume, speed per hour, tire pressure, etc. through the display screen centralized management module 3013; the multimedia playing application 3033 in the entertainment subsystem 303 indirectly controls and uses the main IVI screen 3031 and the auxiliary IVI screen 3032 to play multimedia through the display screen centralized management module 3013.
Fig. 4 shows a software architecture adopted by the left and right rearview mirror subsystems 301 to control the multiple display screens to synchronously display the same target resource (e.g., power-on animation or power-off animation) through the display screen centralized management module 3013.
As shown in fig. 4, the display screen centralized management module 3013 is configured to: acquiring a target resource; then, a Video Processing Unit (VPU) thread 30131 is started to decode the target resource, and an animation playback thread 30132 is started at the same time; the Video Processing Unit (VPU) thread 30131 sends the animation data obtained from the decoding target resource to the playback thread, and then the animation playback thread 30132 takes charge of the animation playback logic on each screen, and sends the animation data to each display screen: a left rear view mirror 3011, a right rear view mirror 3012, a streaming media (HUD) 3021, a dashboard 3022, an IVI main screen 3031, and an IVI sub screen 3032, etc., for synchronous display.
The left and right rearview mirror applications 3014 notify the display screen centralized management module 3013 through interprocess communication when the left rearview mirror 3011 and the right rearview mirror 3012 are needed to display information; then, the display centralized management module 3013 ends playing the target resource in the left rear view mirror 3011 and the right rear view mirror 3012 through the animation playing thread 30132.
When the streaming media application 3023 needs to use the streaming media 3021 projection information, the display screen centralized management module 3013 is notified through inter-core communication; then, the display screen centralized management module 3013 ends playing the target resource in the streaming media 3021 through the animation playback thread 30132.
When the dashboard 3024 needs to display dashboard data using the dashboard 3022, it notifies the display screen centralized management module 3013 through inter-core communication; then, the display centralized management module 3013 ends the playback target resource in the dashboard 3022 via the animation playback thread 30132.
When the multimedia playing application 3033 needs to play multimedia by using the IVI main screen 3031 and the IVI sub screen 3032, the display screen centralized management module 3013 is informed through inter-core communication; then, the display screen centralized management module 3013 ends playing the target resource in the IVI main screen 3031 and the IVI sub screen 3032 through the animation playing thread 30132.
Fig. 5 illustrates a display frame used in the display screen centralized management module 3013. Referring to fig. 5, each Display screen managed in the Display screen centralized management module 3013 corresponds to a Display Controller (DC) 501. The display controller 501 sets a plurality of display layers (layers): the display layer 1, the display layer 2, the display layer 3 and the display layer 4 are used for acquiring corresponding display data from a plurality of data sources. The display layer 1 is used for displaying a video or an image which needs to be subjected to color conversion; the display layer 2 is used for displaying an image without color conversion; the display layer 3 is for displaying display data output from the display processor DP 1; the display layer 4 is used to display the display data output from the display processor DP 2. Then, the display data (including the color of each pixel) of each display layer and the background color are subjected to pixel color combination processing (Alpha Blending) to obtain the display data to be finally displayed on the display screen, and the display data is sent to the display interface. After the display screen receives the display data through the display interface, the display data can be displayed on the display screen.
The display layer 1 and the display layer 2 may be controlled by the display screen centralized management module 3013, and are configured to display the target resource in each display screen synchronously.
The display processor DP1 and the display processor DP2 may use a dedicated communication channel or a general inter-core communication module to communicate with each subsystem (e.g., the dashboard subsystem 302 or the entertainment subsystem 303), obtain instructions and output information sent by each subsystem, perform corresponding processing according to the instructions and the output information, and output display data expected to be displayed by the corresponding subsystem. In this way, each subsystem can be caused to display the display data output by the corresponding application in the corresponding display screen through the display processor DP1 and the display processor DP 2.
Taking the display of the boot animation as an example, after booting, the display screen centralized management module 3013 may send display data of the boot animation to the display layer 1 of the display controller 501 of each display screen through the display layer 1, where each subsystem is not yet started at this time, and the display layer 3 or the display layer 4 does not have any display data. At this time, the display data after the pixel color combination processing is the display data of the boot animation. Therefore, the display screens can synchronously display the startup animation.
When the subsystem is started up, and the display screen centralized management module 3013 is notified through inter-core communication that the corresponding application is started, the display screen centralized management module 3013 may stop sending the boot animation data to the display layer 1 of the display controller 501 of the corresponding display screen, and the display screen may end playing the boot animation. Then, the display layer 3 and the display layer 4 of the display controller 501 receive the display data sent by the corresponding subsystem, and the display layer 1 and the display layer 2 do not have any display data any more, so that each display screen displays the display data of the corresponding application in the corresponding subsystem.
In the embodiment of the present application, since the configurations of the display screens are different (for example, the resolutions, the sizes, the aspect ratios, and the like are different), if the acquired target resource is directly sent to the display screens, problems such as mismatch with the display screens, image missing or distortion, and the like are likely to occur.
Therefore, in the embodiment of the application, the configuration information of each display screen may be stored in advance, the configuration information of each display screen is obtained before the animation playing thread 30132 sends the target resource to each display screen, and the target resource is customized according to the configuration information, so as to obtain the customized resource corresponding to each display screen. Therefore, the target resource can obtain better display effect in each display screen.
Fig. 6 shows a main flow of the left and right rearview mirror subsystems 301 of the first subsystem for centrally controlling the display target resources of the display screens through the display screen centralized management module 3013, including:
step S6010, pre-storing the target resource in the target data storage area.
In the embodiment of the present application, in order to adapt the display contents of different display screens, when packaging the target resource, the resolution is 5760 × 720, and a separate partition of a memory card, for example, a multimedia MMC (eMMC) card, is used as the target data storage area.
Step S6020, in the system start-up process, loads the target data storage area to the first subsystem.
Step S6030, the target resource to be displayed is acquired from the target data storage area.
Therefore, the target resource does not need to be downloaded, and the time for acquiring the target resource is greatly shortened.
In step S6040, the Video Processing Unit (VPU) thread 30131 is started to decode the target resource.
After the VPU decodes, a large buffer of data can be generated.
In step S6050, an animation playback thread 30132 is started.
In step S6060, the animation playback thread 30132 performs customization processing on the target resource according to the configuration information, and obtains a customized resource corresponding to each display screen.
