Abstract
A parallel pipelining method of operation of a touch sense controller for processing data into a touch map is disclosed. A current full scan of response signals to at least one excitation of a touch sense array is received using a first thread of a processing device. The current full scan of response signals is processed using a second thread of the processing device to render a touch map corresponding to the touch sense array. A next full scan of response signals is received using the first thread. Receiving the next full scan and processing the current full scan are performed substantially simultaneously.
