13 to 14B are diagrams referred to in the description of FIG. 10 .

First, in FIG. 13 , on a hypervisor 505 in a processor 175 in a system 500 according to an embodiment of the present invention, the first to third virtualization machines 520 to 540 are executed, and the processor ( So that the first virtual machine 520 in the 175, the second virtual machine 530 and the third virtual machine 540, for the same data transfer, the hypervisor 505 based shared memory 508 is set control is exemplified.

Accordingly, it is possible to synchronize and display the same image on the plurality of displays 180a to 180b in the vehicle.

On the other hand, it is possible to perform high-speed data communication between a plurality of virtual machines. Furthermore, even if a plurality of virtual machines are driven by different operating systems, it is possible to perform high-speed data communication.

On the other hand, when the first virtual machine 520 in the processor 175 transmits data processed in the first virtual machine 520 to another virtual machine, it is not allocated a number of memory corresponding to the number of virtual machines. , one shared memory 508 may be used. Accordingly, using the shared memory 508 instead of 1:1 data communication between virtual machines, 1:N data communication is possible.

Meanwhile, the first virtual machine 520 in the processor 175 may include an input/output server interface 522 and a security manager 526 .

Meanwhile, the second virtual machine 530 and the third virtual machine 540 may include input/output client interfaces 532 and 542, respectively. Accordingly, using the input/output server interface 522 and the input/output client interfaces 532 and 542, it is possible to perform high-speed data communication between a plurality of virtual machines.

The input/output server interface 522 in the first virtual machine 520 receives the same data transfer request from the respective input/output client interfaces 532 and 542 in the second virtual machine 530 and the third virtual machine 540, Based on this, the shared data may be transmitted to the shared memory 508 through the security manager 526 .

14A illustrates a more detailed diagram for shared data transmission.

Referring to the drawing, for shared data transmission, the input/output server interface 522 in the first virtual machine 520 transmits an allocation request of the shared memory 508 to the security manager 526 (S1).

Next, the security manager 526 may allocate the shared memory 508 using the hypervisor 505 ( S2 ), and write the shared data to the shared memory 508 .

Meanwhile, the input/output client interfaces 532 and 542 may transmit a connection request to the input/output server interface 522 after allocation of the shared memory 508 ( S3 ).

On the other hand, the input/output server interface 522 transmits information on the shared memory 508 including key data to the input/output client interfaces 532 and 542 after the shared memory 508 is allocated (S4). At this time, the key data may be private key data.

That is, on the other hand, the first virtual machine 520 in the processor 175, after the setting of the shared memory 508, information about the shared memory 508, the second virtual machine 530 and the third virtual machine ( 540) can be transmitted.

Next, the input/output server interface 522 in the first virtual machine 520 controls to create a command queue for processing commands or events, separate from data, for controlling distributed processing between virtual machines. (S5).

In the figure, it is exemplified that a command queue is generated in the command queue buffer 504 in the hypervisor 505 under the control of the input/output server interface 522 . However, the present invention is not limited thereto, and by the control of the input/output server interface 522 , it is also possible to create within the first virtual machine 520 , not within the hypervisor 505 .

Next, each of the input/output client interfaces 532 and 542 accesses the command queue buffer 504 to receive the generated command queue or information on the command queue (S6).

For example, when commands to the input/output client interfaces 532 and 542 are the same, the generated command queues may be the same.

As another example, when commands to the input/output client interfaces 532 and 542 are different from each other, different command queues may be delivered to the input/output client interfaces 532 and 542 respectively.

Next, each input/output client interface 532, 542, the input/output client interface 532, 542 accesses the shared memory 508 based on the received key data (S5), and transfers the shared data to the shared memory 508 It can be copied or read from (S7).

In particular, when the input/output client interfaces 532 and 542 receive the same shared data, the input/output client interfaces 532 and 542 access the shared memory 508 based on the same command queue and the same key data (S5). ), the shared data may be copied or read from the shared memory 508 .

Accordingly, the second virtual machine 530 and the third virtual machine 540 may access the shared memory 508 , and eventually, the shared data may be shared.

For example, when the shared data is image data, the second virtual machine 530 and the third virtual machine 540 share the image data, and eventually share the same in the plurality of displays 180a to 180b in the vehicle. The video can be displayed in synchronization.

In FIG. 14B , synchronization of the image 905a displayed on the first display 180a and the image 905b displayed on the second display 180b is performed, and the same images 905a and 905b are respectively displayed at a time T1. foreshadows to be

That is, the image data processed by the first virtual machine 520 in the processor 175 is transmitted to the second virtual machine 530 and the third virtual machine 540 through the shared memory 508 , and the image data Based on , the first image 905a displayed on the first display 180a and the second image 905b displayed on the second display 180b may be identical to each other. Accordingly, it is possible to synchronize and display the same image on the plurality of displays 180a to 180b in the vehicle.
