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.

receiving sensor data directly from a sensor by a signal multiplexing module;

outputting a first sensor data stream and a second sensor data stream from the signal multiplexing module of the sensor data received from the sensor, the first sensor data stream having different data stream parameters from the second sensor data stream;

filtering, using a first digital filter coupled to the signal multiplexing module, the first sensor data stream to create a first filtered sensor data stream;

filtering, using a second digital filter coupled to the signal multiplexing module and concurrently with filtering the first sensor data stream using the first digital filter, the second sensor data stream to create a second filtered sensor data stream;

receiving the first filtered sensor data stream at a first output register;

receiving the second filtered sensor data stream at a second output register;

receiving, at a sensor addressing module, a first query regarding available streams;

receiving, at the sensor addressing module, a set of requested data stream parameters;

communicating a response to the first query regarding available streams;

receiving, at the sensor addressing module, a first request for the first sensor data stream from a first application resulting from the response, the sensor addressing module communicatively coupled to the first and second output registers;

receiving, at the sensor addressing module, a second request from a second application for the second sensor data stream;

concurrently outputting at least a first portion of the first filtered sensor data stream from the first output register and at least a second portion of the second filtered sensor data stream from the second output register via the sensor addressing module.

The method of claim 1 wherein concurrently outputting at least the first portion of the first sensor data stream from the first output register and at least the second portion of the second sensor data stream from the second output register via the sensor addressing module comprises communicating the first filtered sensor data stream to the first application beginning at a first time and ending at a second time and communicating the second filtered sensor data stream to the second application beginning at a third time and ending at a fourth time, wherein the third time is later than the first time and the third time is earlier than the second time.

3. The method of claim 1 further comprising:

communicating, from the sensor addressing module to the first digital filter, the set of requested data stream parameters; and

updating the first sensor data stream using the set of requested data stream parameters at the first digital filter prior to communicating the response to the first query.
