Abstract
System and method for substantially reducing an involvement of an applications processor in receiving data from a touchscreen display. In one aspect, the system includes a controller may be configured in an autonomous mode where it automatically measures the touchscreen display based configuration information received from the applications processor, determines notable events based on the measurement data, stores data and event identifiers related to the notable events in a memory, and sends a notification to the applications processor when event data is available In another aspect, the system includes a controller that filters user interactions events and transmits data related to only notable events to the applications processor. Because of the autonomous and event filtering operations of the touchscreen controller, there are substantially less communications between the controller and the applications processor. This improves the speed and efficiency of the applications processor.
