    Abstract: Systems and methods are disclosed for determining a touch position from data received from a touch panel. In one implementation, an apparatus for processing a touch input signal includes a processor that may be configured for parallel processing, a touch device, a memory, operably connected to the processor, and configured to store processor instructions. The processor instructions can configure the processor to receive a plurality of data points corresponding to a plurality of touch events on the touch device, determine a center of mass estimate from the plurality of data points, determine a search radius of center of mass estimate, and determine an optimal touch point position based on the center of mass estimate and the search radius using the processor.

    Abstract: Systems, methods, and apparatus for communication virtualized general-purpose input/output (GPIO) signals over a serial communication link. A method performed at a device coupled to a serial bus includes determining that GPIO state information corresponding to a physical GPIO pin or signal is available in an event register that has a first bit width and includes information identifying one or more devices associated with the event register, and exchanging the GPIO state information with the one or more devices over the serial bus. The GPIO state information may be transmitted over the serial bus in accordance with configuration information stored in the event register. The configuration information may include an address identifying the one or more devices. The configuration information may include addressing information identifying a target register in the one or more devices. The configuration information may include information identifying a mode of communication for transmitting the GPIO state information.

    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: Systems, apparatus and methods for touch detection are presented. Multiple fingers (two to five) from one hand are tracked based on fast moving fingers being group in a fixed position relative to one another. Touch points are matched from a first time to a second time wherein the matching minimizes relative movement between the tracked fingers. In some embodiments, a touch sensor receives first and second touch data comprising touch detections. A processor matches, for several candidate matches, touch detections from a first set to a second set. For each match, the processor further computes a rotation and translation matrix between the first set and the second set; applies the rotation and translation matrix to the first set to determine a result; and calculate a Euclidian distance between the result and the second set. Finally, the processor selects a match, from the several matches, having a minimum Euclidian distance.
