Abstract
Abstract An architecture for an information appliance adapted for a specific application supports a variety of appliance personalities, relying on a single core technology. The information appliance comprises an application-optimized hardware platform, including a processor, a display coupled to the processor, an input/output device coupled to an information source and to the processor, a user input device, and working memory coupled to the processor. Non-volatile memory is coupled to the processor and stores appliance operating software and application software. The appliance operating software includes logic executed by the processor, which manages information flow from the information source through the working memory to the display, and the application software includes logic executed by the processor and responsive to the user input to manage selection of information from the information source. The appliance operating software includes an operating system kernel that is adapted for the processor, and a system library that includes logic providing an interface to the application software. An operating system service layer provides an abstraction function between the system library and the appliance operating system kernel and hardware, so that the logic in the system library and above, such as in the application itself, is executable with a development platform operating system which is completely different from the operating system of the appliance.
