摘要： 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.

摘要： In a display controller for generating a video sync signal using an external clock, he display controller includes an initializer configured to initialize an internal parameter in response to a frame start signal. A sync signal generation circuit is configured to count the external clock, increase the internal parameter, and generate the video sync signal according to a result of comparing the internal parameter that has been increased with a setting value. An original use of the external clock may not be generating the video sync signal.

摘要： In one example embodiment, a method of operating an image data processing circuit which controls an operation of an organic light-emitting diode (OLED) display includes transforming at least one first RGB value into at least one luminance value and at least one chroma value. The method further includes adjusting the at least one luminance value and the at least one chroma value based on at least one first control value. The method further includes generating at least one second RGB value based on the at least one adjusted luminance value and the at least one adjusted chroma value. The method further includes outputting the second RGB values to the OLED display.
