11. The method of claim 10 , wherein the first SoC is at least substantially identical to the second SoC.

12. The method of claim 10 , further comprising:
shifting one or more operations between the first and second sets of operations to balance processing workload between the first and second SoCs.

13. The method of claim 12 , further comprising:
monitoring a first temperature value adjacent the first SoC; and
monitoring a second temperature value adjacent the second SoC;
wherein the shifting of the one or more operations is responsive to the first and second temperature values.

14. The method of claim 10 , wherein the first set of operations comprises performing computer vision, machine learning, and video encoding and the second set of operations comprises running application logic, performing rendering functions, and managing wireless communications.

15. The method of claim 10 , where the performing the first set of operations comprises driving a first camera and a second camera with the first SoC and the performing the second set of operations comprises driving a first display and a second display with the second SoC.
