    Abstract: A method, an apparatus, and a computer program product for processing touchscreen information are provided. The method may include receiving touchscreen data that includes node values representative of signals generated by a touchscreen panel, generating a first data frame including difference values, and transmitting the first data frame over a control data bus. Each of the difference values may be calculated as a difference between one of the node values and a different node-related value wherein the first data frame has a predefined size. The first data frame may be configured to permit a receiver of the first data frame to reconstruct the touchscreen data without information loss.

    Abstract: Implementations disclosed herein provide systems and methods for improved processing of touch sensor data with improved scalability and reduced standby power. Touch-related algorithms may be partitioned between the touch screen controller and the application processor or host such that the system can function with low standby power and low interface bandwidth while providing a scalable solution for enhanced user experience. In some aspects, a small digital processing engine and memory remains in the analog front end (AFE) of the touch screen controller to perform imagine forming algorithms that are mostly related to noise reduction and filtering schemes.

    Abstract: Methods, systems, computer-readable media, and apparatuses for recognizing touch input for a touch panel are presented. In some embodiments, a method for recognizing touch input for a touch panel includes scanning the touch panel over a first frame including at least one touch panel blob resulting from a touch on the touch panel. The method also includes scanning the touch panel over a second frame including at least one touch panel blob resulting from a touch on the touch panel. The method additionally includes processing the touch panel blob within the first frame based at least in part on a first touch-reporting sensitivity and processing the touch panel blob within the second frame based at least in part on a second touch-reporting sensitivity. The method further includes determining whether a valid touch exists based at least in part on the processing step.
