A method and system for implementing a live operating system upgrade of a computer system. The method includes generating a first copy of a previous operating system environment of the computer system. The computer system is then booted to a subsequent operating system environment.

A development and runtime framework for applications that execute in real-time operating systems. Application development is enhanced through simple instructions that allow a programmer to declare functions and sets of functions as tasks and supertasks, respectively, and manage the execution of functions, tasks and supertasks with priorities. A compiler or pre-processor provides tools for generating the code for tasks and supertasks, and the management code for managing execution. Function calls may be made directly to functions within supertasks via respective entrypoints, and the tasks are managed based on the functions being invoked. Within a supertask, a higher priority function may be runnable while a lower priority function of that supertask is suspended. A cookie is used to recognize when a register update for a supertask may be omitted, enabling more efficient context switching.
