Abstract: A method, executed by an encoding circuit, for selecting an optimal decimated grid includes estimating, among a plurality of decimated grids within a coded block, a weight decimation error for each of a vertical decimated grid and a horizontal decimated grid. A weight decimation error is estimated for each of remaining decimated grids among the plurality of decimated grids based on a corresponding weight decimation error among the vertical decimated grid and the horizontal decimated grid. For each of the plurality of decimated grids, an initial combined error is determined by combining the weight decimation error and a color format choice error. Two decimated grids having the least initial combined errors, among the plurality of decimated grids, are selected as optimal decimated grids.

Abstract: A method for driving a touch sensor controller is provided. The method includes receiving touch data from a touch sensor panel and performing interpolation on the received touch data using characterization parameters according to a size and location of a conductor to increase a number of touch data points.

Abstract: A data processing system includes a scalable encoder including an encoder and a control module. The encoder includes at least two layer encoders and has an encoder configuration determined during initialization. The control module is configured to generate an encoder control code in accordance with transmission conditions of a communication channel, the encoder control code controlling operation of the at least two encoding layers.
