Description

Technical Field

[0001] This application relates to the technical field of application operation, and particularly to a device and method for operating application programs across operating systems. Background Art

[0002] With the continuous development of integrated circuit theory and the emergence of System On Chip (SoC) technology, designers' design capabilities and efficiency for chips have been improved to a certain extent, which has also increased the complexity and scale of chips. In the in-vehicle application scenario, the development of in-vehicle systems has evolved from meeting the driving needs of the main driver to meeting the entertainment needs of the main driver and then to meeting the entertainment needs of passengers. Currently, in order to meet the diverse functional requirements of in-vehicle systems, in-vehicle SoCs often have multiple processor cores with different architectures, and different systems and screens are configured for different processor cores to meet the functional requirements of different people in the in-vehicle scenario.

[0003] However, in the prior art, the most complete functions are configured for the main driver's system, while the rear-row systems are only configured with some simple functions. As a result, when rear-row passengers want to perform functions such as watching movies on their own screens, they still need the main driver to operate and play the movie and then cast it to the passengers' screens. Therefore, this method is not only unsafe and prone to causing safety accidents, but also has low inter-system interaction efficiency. Summary of the Invention

[0004] To solve the deficiencies of the prior art, the purpose of this application is to provide a device and method for operating application programs across operating systems, which facilitates the operation and use of application programs of each other between different operating systems.

[0005] To achieve the above purpose, the method for operating application programs across operating systems provided by this application includes:

[0040] Next, embodiments of the present application will be described in detail with reference to the accompanying drawings.

[0041] Embodiment 1

[0042] An embodiment of the present application provides a method for operating an application across operating systems, which facilitates operating applications across operating systems.

[0043] Figure 1 It is a schematic flowchart of the method for operating an application across operating systems of the present application. Next, reference will be made to Figure 1 The method for operating an application across operating systems of the present application will be described in detail:

[0044] Step S101: The first operating system sends an application start instruction to the second operating system through the first communication interface. Among them, the first operating system runs on the first hardware set of the multi-core heterogeneous system-on-chip, and the second operating system runs on the second hardware set of the multi-core heterogeneous system-on-chip. The first hardware set and the second hardware set belong to different hardware domains, and the first communication interface is the first inter-core communication channel between the hardware domains;

[0045] Step S102: Based on the received application start instruction, the second operating system creates a virtual display to start the corresponding application, and sends the display screen data of the application obtained by the virtual display to the first operating system in real time through the second communication interface. Among them, the second communication interface is the second inter-core communication channel between the hardware domains, and the bandwidth of the second inter-core communication channel is greater than the bandwidth of the first inter-core communication channel;

[0046] Step S103: The first operating system synchronously displays the display screen of the application for the user to view and trigger operations. Based on the user's trigger operation, the first operating system sends an in-application operation instruction including the position information of the trigger operation in the display screen of the first system to the second operating system through the first communication interface;

[0047] Step S104: Based on the position information in the application operation instruction, the application in the second operating system responds to the actual operation in the application corresponding to the position information.

[0048] In this embodiment, the type of the first operating system and the type of the second operating system are the same, both are Android operating systems. In some other embodiments, the types of operating systems include, but are not limited to, Android, Linux, QNX, and FreeRTOS.

[0049] In this embodiment, after the first operating system obtains the display screen data of the application, it converts the format of the display screen data and then synchronously displays it on the first operating system. It can be understood that due to different operating systems and different display screens, it is necessary to convert the format of the display screen data before the display screen is displayed.

[0050] It should be noted that in this embodiment, when the first operating system operates the application of the second operating system, the second operating system starts the application in the background, and the display screen of the application will not be displayed on the screen of the second operating system.

[0051] In this embodiment, before step S101, the first operating system first obtains the application information of each application program in the second operating system through the first communication interface and displays it on the first operating system for the user to select the application program to start. The application information includes but is not limited to application icons, application names, and application identification information.

[0052] It can be understood that the application information is only for the user to know which applications are available on the second operating system, and then select an application to issue an application start operation instruction. In this embodiment, it is the first operating system that obtains the reference information through the first communication interface. In some other embodiments, the application information of the second operating system can also be pre-stored in the first operating system. When it is necessary to operate the application in the second operating system, the first operating system directly reads the pre-stored application information.

[0053] In this embodiment, the first communication interface is socket communication, which is mainly used to transmit operation instructions and operation information. The second communication interface is PCIe. PCIe has a large transmission bandwidth and a fast transmission speed, ensuring the maximum degree of synchronization of operation and display.

[0054] In this embodiment, the protocol data of the socket communication includes a 1-byte data identifier and an 8-byte data content. The data identifier is used to identify the response type of the data content, and the response types include application start, application shutdown, and in-application operation.

[0055] It can be understood that for the operation instruction with the response type of application start, its data content is the application-related information of the application to be started. The application-related information is used for the second operating system to be able to start a matching and unique application. In this embodiment, since the first operating system will obtain the application icon, application name, and application identification information through the second operating system, when the user selects the application to be started, the first operating system will issue an operation instruction with the application data being the application name corresponding to the application. In some other embodiments, the data content may also be the location information and application serial number information of the application in the second operating system, etc.

[0056] In this embodiment, for an operation instruction with an application close response type, when the first operating system wants to exit after finishing the operation on the application of the second operating system, the user can issue an application close instruction through the first operating system. Based on this instruction, the first operating system stops displaying the acquired display screen data and stops acquiring display screen data from the second operating system. At the same time, the second operating system closes the application and destroys the virtual display, ending the cross-system operation of the application.

[0057] In this embodiment, for an operation instruction with an in-application operation response type, the data content is the position information of the trigger operation in the display screen of the first system. In this embodiment, both the first operating system and the second operating system are Android operating systems. When the user starts an application of the second operating system and sees the display screen of the application on the first operating system, when touching the application for operation, the first operating system obtains the position information of the touch operation in the display screen through the actual display window of the first operating system and the reported points of onTouch(), and issues an in-application operation instruction including this position information to the second operating system. After receiving this operation instruction, the second operating system passes it to the virtual display through the interface of InputManager.injectInputEvent(), thereby determining the actual operation of the application and controlling the application to respond.

[0058] Embodiment 2

[0059] An embodiment of the present application provides a device for operating an application across operating systems, facilitating the operation of applications across operating systems between operating systems.

[0060] It should be noted that in this embodiment, the device for operating an application across operating systems of the present application is described in detail with a device for operating an application across two systems. It can be understood that this device can be used between any number of systems.

[0061] Figure 2 It is a schematic structural diagram of the device for operating an application across operating systems of the present application, as Figure 2 shown, including:

[0062] A display control unit 110, a display unit 120, an application startup unit 130, and an image transmission unit 140 configured on the first operating system 100; a display control unit 210, a display unit 220, an application startup unit 230, and an image transmission unit 240 configured on the second operating system 200; the display units, application startup units, and image transmission units in each operating system are all connected to the display control unit of this system, and several applications are respectively installed in each operating system. Exemplarily, applications 301, 302, and 303 are installed in the first operating system 100, and applications 304 and 305 are installed in the second operating system 200.

[0063] Among them, the display control unit 110 and the display control unit 210 are communicatively connected through a first communication interface to transmit application information and operation instructions, and are used to control the display unit, application startup unit, and image transmission unit of this operating system to respond to the operation instructions based on the user operation instructions and the operation instructions sent by other operating systems.

[0064] Exemplarily, taking the first operating system as an example, the functions of each unit are explained. Among them, the application startup unit 130 is used to start the corresponding application in the first operating system based on the operation instructions; the display unit 120 includes a virtual display unit 121 and a physical display unit 122. The virtual display unit 121 is used to capture the display screen data after the application program starts, and the physical display unit 122 is used to display the application information on the screen of the first operating system 100 for the user to select to start or display the display screen data of the application program received by the image transmission unit 140 for the user to view and operate; the image transmission unit 140 is communicatively connected to the image transmission unit 240 on the second operating system 200 through a second communication interface to transmit the display screen data captured by the virtual display unit 121.

[0065] It should be noted that the virtual display unit is created after receiving the application startup instruction, and the physical display unit is created when the image processing unit receives the display screen data of the application and when displaying the application information.

[0066] Among them, each operating system runs on different hardware sets of a multi-core heterogeneous system-on-chip. Different hardware sets belong to different hardware domains. The first communication interface is the first inter-core communication channel between the hardware domains, and the second communication interface is the second inter-core communication channel between the hardware domains. The bandwidth of the second inter-core communication channel is greater than the bandwidth of the first inter-core communication channel.

[0067] It can be understood that the first operating system and the second operating system respectively have screens for their own operating systems to use.

[0068] In this embodiment, the operation instructions include an application start instruction, an in-application operation instruction, and an application close instruction.

[0069] In this embodiment, the application information includes an application icon, an application name, and application identification information.

[0070] In this embodiment, the first communication interface is socket communication, and the second communication interface is any one of Mailbox and PCIe.

[0071] It should be noted that in this embodiment, the image transmission unit 140 uses the v4L2 architecture to transmit the display screen data of the application.

[0072] The working process of this embodiment is as follows: When a user of the first operating system 100 wants to operate an application 305 of the second system 200, the display control unit 110 of the first operating system 100 obtains all the application information on the second operating system 200 from the display control unit 210 of the second operating system and displays it on the screen of the first operating system 100 for the user to select. When the user selects to start the application 305 according to the displayed information, the display control unit 110 of the first operating system 100 sends an application start instruction to the display control unit 210 of the second operating system 200. After receiving the application start instruction, the second operating system 200 controls the application start unit 230 to start the corresponding application 305 and controls the display unit 220 to create a virtual display unit 221 to capture the screen data after the application 305 is started. Synchronously, the image transmission unit 240 transmits the screen data after startup to the image transmission unit 140 of the first operating system 100. After receiving the screen data, the physical display unit 122 displays the screen data on the screen for the user to view and operate the application 305. When the user triggers an in-application operation, the display control unit 110 of the first operating system 100 sends an in-application operation instruction to the display control unit 210 of the second operating system 200. After receiving the in-application operation instruction, the display control unit 210 of the second operating system 200 controls the application 305 to perform the corresponding operation. When the user wants to exit, the display control unit 110 of the first operating system 100 sends an application close instruction to the display control unit 210 of the second operating system 200. At the same time, the display control unit 110 of the first operating system 100 closes the physical display unit 122 to stop displaying the acquired display screen data and controls the image transmission unit 140 to stop acquiring the display screen data. After receiving the application close instruction, the display control unit 210 of the second operating system 200 closes the application and destroys the virtual display, ending the cross-system operation of the application.

[0073] Similarly, the process of a user of the second operating system 200 operating an application of the first operating system 100 will not be elaborated here.

[0074] It should be noted that both the first operating system 100 and the second operating system 200 are Android operating systems. When the user starts an application of the second operating system and sees the display screen of the application on the first operating system, when the user triggers an in-application operation, the display control unit 110 of the first operating system 100 will obtain the position information of the touch operation in the display screen through the actual display window of the first operating system 100 and the reported points of onTouch(). The display control unit 110 of the first operating system 100 sends an in-application operation instruction including the position information to the display control unit 210 of the second operating system 200. After receiving the operation instruction, the second operating system 200 passes it to the virtual display through the interface of InputManager.injectInputEvent(), and then determines the operation that the application 305 actually needs to perform, and controls the application 305 to respond.
