System and method for improved processing of touch sensor data

摘要

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.

1. A system for improved processing of touch sensor data, comprising:
a touch panel; a touch detection module configured to capture touch data comprising at least a first touch event on the touch panel; a touch panel processing module configured to perform initial processing tasks on the touch event data and store filtered data, wherein the initial processing tasks comprise noise reduction functions and image forming functions; and an application processing module configured to perform additional processing tasks on the filtered data, wherein the additional processing tasks comprise touch validation functions.
