    Abstract: The described techniques provide efficient semiconductor device configurations and improved processes for facilitating artificial intelligence operations. In an example, a semiconductor device may be configured with first memory for storing data before an artificial intelligence operation and second memory for storing data after an artificial intelligence operation. The use of the first memory and the second memory for storing data before and after the artificial intelligence operation, respectively, may support a simplified layout for a semiconductor device to facilitate artificial intelligence operations with minimal hardware configurations and limited software. In addition, the use of the first memory and the second memory for storing data before and after the artificial intelligence operation, respectively, may allow for processing when the domains of input data and output data are different.

    Abstract: A luminance compensator includes a memory device and a luminance compensation circuit. The memory device stores a plurality of luminance compensation data and provides first luminance compensation data and second luminance compensation data among the plurality of luminance compensation data in response to a frame rate dimming-on signal. The first luminance compensation data corresponds to a first frame rate. The second luminance compensation data corresponds to a second frame rate. The plurality of luminance compensation data is for compensating luminance of at least one region that operates with a plurality of frame rates. The frame rate dimming-on signal represents time intervals in which frame rates of the at least one region are gradually changed. The luminance compensation circuit generates third luminance compensation data in response to the frame rate dimming-on signal, the first luminance compensation data, and the second luminance compensation data.

    Abstract: A display driver circuit includes a receiver that receives a still image or a moving image, a frame buffer that stores the still image received by the receiver in a still image mode, an image processor that performs an image enhancement operation on the moving image transferred from the receiver or the still image transferred from the frame buffer, and a motion processor that performs a motion compensation operation using a current frame output from the image processor and a previous frame stored in the frame buffer in a moving image mode. The previous frame is data which, in the moving image mode, are processed by the image processor before the current frame and are then stored in the frame buffer. The previous frame is output from the frame buffer to the motion processor in synchronization with the current frame.

    Abstract: Provided are a low-power display driving circuit performing internal encoding and decoding and an operating method thereof. The display driving circuit includes a memory configured to store an input bit stream encoded by an encoder and a controller configured to determine a data path through which output frame data in a second frame period passes according to whether internal encoding is successful in a first frame period, wherein, when the internal encoding is successful, the controller performs internal encoding in the second frame period, stores a generated internal bit stream in the memory, allows the internal bit stream to pass through a low-power path to generate the output frame data, and when the internal encoding fails, the controller generates the output frame data by allowing the input bit stream to pass through a normal path in the second frame period, changes an encoding setting of an internal encoder, and repeats the internal encoding.
