## Abstract

According to an embodiment, a vehicle device where drawing is executed by a plurality of applications includes a GPU that executes drawing based on a drawing request from the plurality of applications, a normal queue to which a drawing request for the GPU is input, and a priority queue to which a drawing request of preferentially executing processing over the normal queue is input. The GPU is configured to process the drawing request input to the normal queue in a round-robin fashion while preferentially processing the drawing request input to the priority queue.

## Claims

a graphic processing unit that draws a surface, which is image data to be displayed on a display device as a content, on at least one of a plurality of physical surfaces based on a drawing request from the plurality of application programs wherein the physical surfaces are storage areas formed on a memory and each of the physical surfaces is individually allocated to a respective one of the plurality of application programs;
a normal queue to which a drawing command for the graphic processing unit is input; and
a priority queue to which a drawing command of preferentially executing processing over the normal queue is input, wherein
the graphic processing unit is configured to process the drawing command input to the normal queue in a round-robin fashion while preferentially processing the drawing command input to the priority queue.

### Claim 2 (depends on 1)

The vehicle device according to claim 1, wherein at least one of the plurality of application programs inputs, to the priority queue, a drawing command for an image that needs to be periodically updated.

### Claim 3 (depends on 1)

The vehicle device according to claim 1, wherein at least one of the plurality of application programs inputs, to the priority queue, a drawing command for an image for displaying a warning.

### Claim 4 (depends on 1)

The vehicle device according to claim 1, wherein at least one of the plurality of application programs:
specifies a priority portion to be preferentially processed in an image for which drawing is requested;
inputs a drawing command for the priority portion to the priority queue; and
inputs a drawing command for a remaining portion other than the priority portion to the normal queue.

### Claim 5 (depends on 4)

The vehicle device according to claim 4, wherein at least one of the plurality of application programs:
inputs a drawing command for an image to be displayed on a meter display configured to provide full graphic display; and
inputs, as the priority portion, at least one of a drawing command for a portion in the image corresponding to an indicator of a meter and a drawing command for a portion in the image corresponding to a warning light of the meter to the priority queue.

### Claim 6 (depends on 4)

The vehicle device according to claim 4, wherein at least one of the plurality of application programs:
inputs a drawing command for an image to be displayed on a meter display configured to provide full graphic display; and
inputs, to the priority queue, a drawing command for deleting the priority portion that has been drawn last time.

### Claim 7 (depends on 1)

The vehicle device according to claim 1, wherein
priorities are given to the plurality of application programs,
a drawing command from the application program having a relatively high priority is input to the priority queue, and
a drawing command from the application program having a relatively low priority is input to the normal queue.
