Abstract: A system on chip (SoC) and a method of operating the same are provided. The SoC includes a central processing unit (CPU) controlling a memory operation and a display operation on a current frame of an image based on generation of the image and an interrupt signal; an image generator requesting data of the current frame from a memory according to control of the CPU; a UD unit determining whether the current frame is updated, detecting whether an update region is a partial frame based on virtual addresses included in a request of the image generator, and outputting the interrupt signal corresponding to the update region to the CPU; a memory controller storing the update region in the memory according to the control of the CPU; and a display controller accessing the memory and outputting the update region to a display device according to the control of the CPU.
