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.
