Integrated hardware and software task control executive

摘要: A method and system for permitting a software-based executive to execute concurrently with hardware-based executive. The allocates hardware tasks, interrupts, software interrupts defined execution spaces available on microprocessor having Applications control tasks through application programming interface (API), API. share the API functions interrupt installation management. invention all high priority space, queue. All are allocated low uses special context switch mechanism that changes currently executing task without creating another task. In this way, scheduler is always disabled, under of hierarchical "enables" protects critical sections code during reentrancies. An return revectoring provided provide preemption. When occurs, exits revectors into kernel so new can begin executing, rather than returning previously also accommodate block move operations.
