CPC classification number: H04W4/02 , G01P13/00 , G01S5/26 , G06F1/12 , G06F1/14 , H04W4/33 , H04W4/80
Abstract: An approach to obtain low latency association of the audio clock in a smartphone with an incoming RF message is to use an interrupt driven routine, where the receipt of the RF message preamble generates an interrupt that reads the audio clock counter since the start of the audio session. In some embodiments such an approach may be implemented on the specialized processing cores found in smartphones that control RF communication, sensor or audio processing.
