Abstract

Selectable communication interface configurations for motion sensing devices. In one aspect, a module for a motion sensing device includes a motion processor connected to a device component and a first motion sensor, and a multiplexer having first and second positions. Only one of the multiplexer positions is selectable at a time, where the first position selectively couples the first motion sensor and the device component using a first bus, and the second position selectively couples the first motion sensor and the motion processor using a second bus, wherein communication of information over the second bus does not influence a communication bandwidth of the first bus.

Claims

1. A module for a motion sensing device, the module comprising:

a device component including a motion processor and at least one first motion sensor, wherein the motion processor comprises a microprocessor;

wherein the motion processor processes a plurality of motion algorithms;

at least one second motion sensor connected to the device component; and

a host processor connected to the device component, where data from the at least one first motion sensor or data from the at least second motion sensor is available to the host processor.

2. The module of claim 1, where the host processor collects data directly from the at least one first motion sensor or data from the at least one second motion sensor.

3. The module of claim 2, where the host processor controls the at least one second motion sensor.

4. The module of claim 1, where the device component further comprises a first memory to directly store data from the at least one first motion sensor or to store data from the at least one second motion sensor.

5. The module of claim 4, where the host processor can request the device component to control the at least one first motion sensor or the at least one second motion sensor.

6. The module of claim 1, where the data from the at least one first motion sensor or the data from the at least one second motion sensor is available for motion processing.

7. The module of claim 1, further comprising a second memory external to the device component for storing the data from the at least one first motion sensor or data from the at least one second motion sensor.
