Abstract: In a method of adaptive buffering in a mobile device having a host processor and a sensor processor coupled with the host processor, the sensor processor is used to buffer data received from a sensor that is operated by the sensor processor, wherein the data is buffered by the sensor processor into a circular data buffer. In response to the sensor processor detecting triggering data within the received data: the sensor processor sets a start-end marker in the circular data buffer; and a command is sent from the sensor processor to a second processor.

Abstract: A sensor processing unit comprises a microphone and a sensor processor. The sensor processor is coupled with the microphone. The sensor processor is configured to operate the microphone to capture an audio sample from an environment in which the microphone is disposed. The sensor processor is configured to perform music activity detection on the audio sample to detect for music within the audio sample. Responsive to detection of music within the audio sample, the sensor processor is configured to send a music detection signal to an external processor located external to the sensor processing unit, the music detection signal indicating that music has been detected in the environment.

Abstract: Systems and techniques for providing improved beam forming functionality and/or improve noise cancellation functionality in a microphone package are presented. In an implementation, a device includes a first microelectromechanical systems (MEMS) sensor, a second MEMS sensor, and a digital signal processor. The first MEMS sensor is contained in a first back cavity within the device. The second MEMS sensor is contained in a second back cavity within the device. The digital signal processor generates a cardioid microphone pattern based on data associated with the first MEMS sensor contained in the first back cavity and other data associated with the second MEMS sensor contained in the second back cavity, where the digital signal processor forms at least a portion of the first back cavity and the second back cavity.
