Abstract
Systems and methods for improving operation of an electronic device that includes a processing pipeline. The processing pipeline includes a prediction block that determines prediction residuals based on difference between uncompressed image data corresponding with a pixel tile and prediction of a first pixel group in the pixel tile and difference between the uncompressed image data and prediction of a second pixel group in the pixel tile, a run encode block that replaces a first of the prediction residuals with an escape value and a second of the prediction residuals with a run length value when a run starting in the first pixel group and continuing into the second pixel group is detected, and an entropy encode block that generates compressed image data corresponding with the pixel tile by entropy encoding a third of the prediction residuals, the escape value, and the run length value when the run is detected.
