Novel personal electronics device with simultaneous multi-processor operation
First Claim
1. A personal electronics device comprising:
- a non-embedded processor configured to perform a set of functions;
an embedded processor configured to perform a limited set of functions compared to the non-embedded processor and configured to control operation of the non-embedded processor;
a display coupled to the embedded processor and the non-embedded processor and configured to selectively display information from the embedded processor and the non-embedded processor; and
an input device coupled to the embedded processor and non-embedded processor to allow a user to provide instructions to the embedded processor and non-embedded processor;
wherein the embedded processor and non-embedded processor are configured to selectively operate simultaneously.

Abstract
A novel personal electronic device includes a first (embedded) and second (non-embedded) processors including associated operating systems and functions. In one aspect, the first processor performs relatively limited functions, while the second processor performs relatively broader functions under control of the first processor. Often the second processor requires more power than the first processor and is selectively operated by the first processor to minimize overall power consumption. Protocols for functions to be performed by the second processor may be provided directly to the second processor and processed by the second processor. In another aspect, a display controller is designed to interface with both processors. In another aspect, the operating systems work with one another. In another aspect, the first processor employs a thermal control program. Advantages of the invention include a broad array of functions performed by a relatively small personal electronics device.
