Abstract

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