Signal processing device and display apparatus for vehicle including the same

A processing device comprising:

• a processor configured to perform signal processing for a first display and a second display that are configured to be located in a vehicle, wherein:
• the processor is configured to execute first, second, and third virtual machines on a hypervisor in the processor, the second virtual machine is configured to be operated for the first display, the third virtual machine is configured to be operated for the second display, and the first virtual machine executed in the processor comprises:
• a first interface configured to receive sensor data from a sensor device in the vehicle and a radio signal from a tuner in the vehicle, and an input and output server interface configured to transmit, to at least one of the second virtual machine or the third virtual machine, data corresponding to the sensor data or the radio signal received from the first interface, and wherein the first virtual machine is configured to:
• receive, through the first interface, air conditioning data of the vehicle, process the received air conditioning data, and
• transmit, to at least one of the second virtual machine or the third virtual machine through the input and output server interface, the processed air conditioning data.
