Abstract

Multiple processor systems are provided. A first processor is configured to monitor the state of at least one other processor by comparing received signals. When the first processor determines that another processor needs to be reset, the first processor provides a reset signal to a reset pin of the processor that needs to be reset. The first processor may reset itself after providing the reset signal.

Claims

1. A device comprising:

a first processor and a second processor each configured to receive an input signal;

wherein the first processor is configured to process the input signal to generate an output signal and transmit the output signal to the second processor;

wherein the second processor is configured to

(i) compare the input signal to the output signal to determine whether the input signal corresponds to the output signal, and

(ii) transmit a reset signal to the first processor in response to determining that the input signal does not correspond to the output signal; and

wherein the first processor is further configured to load firmware in response to receiving the reset signal.

2. The device of claim 1, wherein the input signal comprises a power signal.

3. The device of claim 2, wherein the power signal comprises a USB VBUS signal.

4. The device of claim 1, further comprising a wireless receiver configured to transmit the input signal to the first processor and the second processor.

5. The device of claim 1, wherein the input signal has a first voltage level and the output signal has a second voltage level.

6. The device of claim 5, wherein the second processor is configured to compare the input signal to the output signal by comparing the first voltage level to the second voltage level.

7. The device of claim 1, wherein the second processor is configured to compare the input signal to the output signal by comparing first timing information of the input signal to second timing information of the output signal.

8. The device of claim 1, wherein the second processor is configured to reset after transmitting the reset signal to the first processor.

9. The device of claim 1, wherein the device is configured to be worn by a user and further comprising:

at least one sensor configured to measure movements of the user while the device is worn by the user; and

a memory configured to store movement data generated by the at least one sensor and corresponding to the movements of the user.

10. The device of claim 9, wherein the device is configured to be incorporated into an article of apparel worn by the user.

11. The device of claim 10, wherein the article of apparel comprises one of a watch, an armband, a wristband, a necklace, a shirt, or a shoe.

12. The device of claim 9, wherein the device is configured to by worn around a wrist of the user.

13. The device of claim 9, wherein the at least one sensor comprises an accelerometer.

14. The device of claim 13, wherein the accelerometer comprises a multi-axis accelerometer.

15. The device of claim 9, wherein the device is configured to form at least one parameter based on the movement data generated by the at least one sensor.

16. The device of claim 15, wherein the at least one parameter comprises one or more of a speed of the user, a distance traveled by the user, a number of steps taken by the user, an energy expenditure of the user, activity points earned, or currency earned.

17. The device of claim 1, further comprising:

a battery; and

a wireless power receiver configured to charge the battery in response to wireless electromagnetic energy received.

18. The device of claim of claim 17, wherein the battery is configured to initiate a reset process for the first processor and the second processor in response to receiving energy from the wireless power receiver.

19. The device of claim 1, further comprising:

a button configured to initiate a reset process for the first processor and the second processor when pressed.

20. A device comprising:

a first processor and a second processor each configured to receive an input signal;

wherein the second processor is configured to transmit, to the first processor, a reset signal in response to determining that the input signal does not correspond to an output signal generated by and received from the first processor which is configured to process the input signal to generate the output signal; and

wherein the first processor is further configured to load firmware in response to receipt of the reset signal.
