The user can input an operation request to a target application of at least one operating system in the CPU, and the CPU receives the operation request of the target application of each operating system. For example: the CPU is internally provided with an Android operating system, a Mac operating system and a Linux operating system, and each operating system is provided with at least one target application. A user inputs an operation request to a target application in an Android operating system and a Mac operating system, and at the moment, a CPU receives the operation request of the target application in the Android operating system and the Mac operating system.

And the CPU responds to the operation of clicking the icon of the target application of each operating system input by the user and acquires a plurality of target layers generated when the target application of each operating system is operated.
Fig. 3 is a flowchart for acquiring multiple target layers according to an embodiment of the present invention, where as shown in fig. 3, the operation request is an operation of clicking an icon of a target application 1 of an operating system 1 and an operation of clicking an icon of a target application 2 of an operating system 2 in a CPU by a user, and a target layer 1, a target layer 2, and a target layer 3 are generated when the target application 1 is operated, and the CPU acquires the target layer 1, the target layer 2, and the target layer 3 in response to the operation of clicking the icon of the target application 1, which is input by the user; and generating a target layer 4 and a target layer 5 when operating the target application 2, and acquiring the target layer 4 and the target layer 5 by the CPU in response to the operation of clicking the icon of the target application 2 input by the user.
In the embodiment of the invention, each target layer can be bound to any operating system, and each target layer can exist independently or be updated and combined. For example, target layer 1, target layer 2, and target layer 3 of target application 1 of operating system 1 may be bound to any operating system, and each target layer may exist independently; or, the target layer 1 may be bound to the operating system 2, and the target layer 1, the target layer 4, and the target layer 5 may be combined.
And 103, the DPU acquires the plurality of target layers of each operating system from the CPU, and performs synthesis processing on the plurality of target layers of each operating system to generate display data of each operating system.
The DPU acquires a plurality of target layers of the target application in each operating system from the CPU, and the DPU performs synthesis processing on the plurality of target layers of the target application in each operating system to generate display data of the target application in each operating system. For example, the DPU obtains, from the CPU, a target layer 1, a target layer 2, and a target layer 3 of a target application 1 in the operating system 1, and a target layer 4 and a target layer 5 of a target application 2 in the operating system 2, and performs synthesis processing on the target layer 1, the target layer 2, and the target layer 3 of the target application 1 in the operating system 1 to generate display data of the target application 1 in the operating system 1; the DPU performs synthesis processing on the target layer 4 and the target layer 5 of the target application 2 in the operating system 2 to generate display data of the target application 2 in the operating system 2.

In the embodiment of the present invention, each operating system corresponds to a global interrupt request one by one, for example, operating system 1 corresponds to global interrupt request 1; operating system 2 corresponds to global interrupt request 2.
And the CPU responds to the global interrupt request of the target application in each operating system and sends the acquired multiple target layers corresponding to the target application of each operating system to the DPU according to the frame rate. For example, in response to a global interrupt request 1 of a target application 1 in an operating system 1, a CPU sends a target layer 1, a target layer 2, and a target layer 3 corresponding to the target application 1 in the operating system 1 to a DPU according to a frame rate; and the CPU responds to the global interrupt request 2 of the target application 2 in the operating system 2 and sends the acquired target layer 4 and target layer 5 corresponding to the target application 2 in the operating system 2 to the DPU according to the frame rate.

As shown in fig. 3, the interrupt request includes an update interrupt request. The DPU sends an update interruption request of the target application in each operating system to the CPU in response to the display data update request of the target application. For example, the DPU sends an update interruption request 1 of the target application 1 in the operating system 1 to the CPU in response to the display data update request of the target application 1; the DPU sends an update interruption request 2 of the target application 2 in the operating system 2 to the CPU in response to the display data update request of the target application 2.
In the embodiment of the present invention, each operating system corresponds to an update interrupt request one by one, for example, the operating system 1 corresponds to the update interrupt request 1; the operating system 2 corresponds to the update interrupt request 2.
For example, in response to an update interruption request 1 of a target application 1 in an operating system 1, a CPU obtains an updated target layer 1, a target layer 2, and a target layer 3 generated when the target application 1 of the operating system 1 is subjected to an update operation, and sends the updated target layer 1, the target layer 2, and the target layer 3 corresponding to the target application 1 in the operating system 1 to a DPU; the CPU, in response to the update interruption request 2 of the target application 2 in the operating system 2, acquires an updated target layer 4 and a target layer 5 generated when the target application 2 of the operating system 2 is subjected to an update operation, and sends the updated target layer 4 and the updated target layer 5 corresponding to the target application 2 in the operating system 2 to the DPU.
And step 304, the DPU synthesizes the plurality of updated target layers of each operating system to generate updated display data of each operating system.
And the DPU performs synthesis processing on the plurality of updated target layers of the target application in each operating system to generate updated display data of the target application in each operating system.
