1. A processor chip configured to perform neural network processing, comprising:
a neural processing unit (NPU), comprising a processor, configured to perform the neural network processing on data;
a central processing unit (CPU) comprising a processor;
a third processor; and
a memory configured to include a secure area that is accessible by the neural processing unit and is not accessible by the central processing unit, and an unsecure area accessible by the neural processing unit and the central processing unit,
wherein the central processing unit is configured to control to transmit a start signal to the third processor to cause the third processor to provide address information of one of a plurality of artificial intelligence models stored in the unsecure area included in the memory,
wherein the third processor is configured to:
identify the one of the plurality of artificial intelligence models based on a resolution of an input content,
provide the address information of the one of the plurality of artificial intelligence models to the neural processing unit so that the neural processing unit can perform the neural network processing by accessing the secure area based on the address information.
