Abstract: Exemplary embodiments disclose a system-on-chip (SoC) including a special function register (SFR) and an operating method thereof. The SFR comprises a first update storage element, a second update storage element, a first update logic corresponding to the first update storage element, and a second update logic corresponding to the second update storage element, wherein a clock is supplied to the first update storage element in response to the first update logic being enabled, and the clock is supplied to the second update storage element in response to the second update logic being enabled.

Abstract: 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.
