摘要： The signal processing device includes a processor to execute a plurality of virtual machines, a first memory to store a file corresponding to a first application executed based on entry into a standby mode, and a second memory to load a file stored in the first memory based on the switching from the standby mode to an active mode, wherein the processor is configured to restore the first application based on the file loaded to the second memory during the switching from the standby mode to the active mode, terminate a second application executed in another virtual machine based on the entry into the standby mode, turn on the other virtual machine based on the switching from the standby mode to the active mode, and execute the second application after an operating system is executed. Accordingly, it is possible to shorten a booting period or wakeup period of some applications that are executed in the vehicle.
