Abstract

Embodiments implement a device having a sensor element, where different data streams created as part of a sensor module integrated with the sensor element may create multiple sensor data streams from a single sensor element, and may concurrently convey information from the sensor element to respective different applications having different data parameter requirements such that the data streams each match the parameter requirements of the different applications.

Claims

1. A device comprising:

a first sensor element;

a plurality of digital filters, each of the digital filters coupled in parallel with each other to the first sensor via a signal multiplexer, wherein the plurality of digital filters comprises more than one digital filter;

a plurality of output registers, each output register coupled to one corresponding digital filter of the plurality of digital filters; and

a sensor addresser coupled to the plurality of output registers, wherein the sensor addresser concurrently outputs at least two sensor data streams, wherein the at least two sensor data streams are received at the sensor addresser from the plurality of output registers, and wherein the at least two sensor data streams have different data stream parameters.

2. The device of claim 1 further comprising:

a processor communicatively coupled to the sensor addresser that provides a first set of data stream parameters and a second set of data stream parameters which are used to create the different data stream parameters for the at least two sensor data streams.

3. The device of claim 2 wherein the processor executes a plurality of applications, each application of the plurality of applications providing a set of data stream parameters to the processor for communication to the sensor addresser as part of a request for sensor data by each application of the plurality of applications.

4. The device of claim 3 further comprising a first calibration module;

wherein the plurality of digital filters comprises a first digital filter and a second digital filter;

wherein the plurality of output registers comprises a first output register coupled to the first digital filter and a second output register coupled to the second digital filter; and

wherein the first digital filter is coupled to the first output register via the first calibration module.

5. The device of claim 4 wherein the first sensor element is a gyroscope sensor element and wherein the at least two sensor data streams comprise a calibrated sensor data stream and an uncalibrated sensor data stream.

6. The device of claim 5 wherein a first application of the plurality of applications is a camera application that receives the calibrated sensor data stream from the first output register and wherein a second application of the plurality of applications is a navigation application that receives the uncalibrated sensor data stream from the second output register.

7. The device of claim 1 wherein the signal multiplexer-further comprises an analog to digital converter and wherein the plurality of digital filters is integrated with the analog to digital converter.

8. The device of claim 7 wherein the first sensor element is a microphone and wherein the signal multiplexer and the plurality of digital filters are part of a single integrated circuit.
