Signal processing device and vehicle display apparatus including the same

A signal processing device comprising:

• a processor including a plurality of processor cores, wherein
• the processor is configured to execute a plurality of virtual machines on a hypervisor, and
• a first virtual machine among the plurality of virtual machines is configured to:
• transmit first data to a second virtual machine through Ethernet communication or a shared memory within the hypervisor, and
• transmit second data to an external signal processing device through the Ethernet communication or peripheral component interconnect express communication.
• wherein the first virtual machine is configured to execute an application or microservice corresponding to a first safety level or execute an application or microservice corresponding to the second safety level higher than the first safety.
• wherein the second virtual machine is executed on an operating system corresponding to a third safety level lower than the first safety.

A vehicle display apparatus comprising:

• at least one display;
• and
• a signal processing device configured to output a video signal to the display,
• wherein the signal processing device comprises a processor including a plurality of processor cores,
• wherein the processor is configured to execute a plurality of virtual machines on a hypervisor, and
