Abstract

A system on chip (SoC) for updating a partial frame of an image 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.

Description

[0001] This application claims priority from Korean Patent Application No. 10-2013-0012007 filed with the Korean Intellectual Property Office on February 1, 2013, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0002] Embodiments of the inventive concept relate to a system on chip (SoC), and more particularly, to an SoC for updating a partial frame of an image, and a method of operating the same. Background technique [0003] As image resolutions in mobile devices increase, data communication between mobile application processors and display driver integrated circuits (ICs) is rapidly increasing. Consequently, the power consumption of mobile application processors and / or display driver ICs is also increasing. [0004] Conventional mobile phones, which mainly involve voice calls, have been rapidly replaced by smart phones, which process and display large amounts of multimedia data. Display driver ICs implemented in smartphones f...
