Abstract: Provided is a control method of a deep neural network (DNN) accelerator for optimized data processing. The control method includes, based on a dataflow and a hardware mapping value of neural network data allocated to a first-level memory, calculating a plurality of offsets representing start components of a plurality of data tiles of the neural network data, based on receiving an update request for the neural network data from a second-level memory, identifying a data type of an update data tile corresponding to the received update request among the plurality of data tiles, identifying one or more components of the update data tile, based on the data type of the update data tile and an offset of the update data tile among the calculated plurality of offsets, and updating neural network data of the identified one or more components between the first-level memory and the second-level memory.

Abstract: A display device includes a display panel including a plurality of data lines; a plurality of data drive ICs configured to provide data voltages to the data lines; and a controller configured to rearrange video data received from an external device and transmit region-wise video data to the plurality of data drive ICs, to receive coordinates of information regions included in the video data and store video data of the information regions in advance, to calculate a checksum for checking an error in the region-wise video data based on the coordinates, to transmit the coordinates and the checksum to the data drive ICs and receive feedbacks about comparison results with respect to the checksum, and when a data drive IC that has failed is confirmed based on the feedback results, to update video data of the information region displayed by the data drive IC to region-wise video data of a normal data drive IC and output the video data.
