A multimedia system includes a main special function register (SFR) configured to store SFR information; a plurality of processing modules each configured to process frames of data, based on the SFR information; and a system control logic configured to control operations of the main SFR and the plurality of processing modules. The plurality of processing modules may process data of different frames at the same time period.

Multimedia system and operating method of the same

A system-on-chip (SoC) which includes a plurality of intellectual properties (IP cores) which communicate data with a memory device operates by monitoring whether a data transaction occurs between at least one of the IP cores and the memory device, determining an operation state of the IP core according to the result of the monitoring, and supplying the IP core with power corresponding to the operation state of the IP core.

System-on-chip with capability for controlling power supply according to data transaction and method of operating the same

An image sensor includes a pixel array including at least one active pixel and at least one line-optical black (L-OB) pixel arranged in a matrix including first to nrows and first to mcolumns, the pixel array configured to output a pixel signal and a dark-level offset signal in units of columns during a read-out operation in one of the first to nrows; a row driver configured to output a selection control signal to the first to nrows; and an analog-to-digital converter (ADC) block configured to digitize the pixel signal and the dark-level offset signal. In the pixel array, a dark-level offset signal is simultaneously output from an L-OB pixel in another row during the read-out operation in one of the first to nrows. Here, 'n' and 'm' each denote an integer that is equal to or greater than &#x2018;2&#x2019;.

Image sensor

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.

Methods and devices for controlling operations of an organic light-emitting diode display

A multiplication method and a modular multiplier are provided. The multiplication method includes transforming a redundant-form multiplier by adding a recoding constant to the multiplier, performing recoding by using the transformed multiplier, and performing partial multiplication between the multiplier and a multiplicand using result values of the recoding.
