Abstract
Method for executing a task composed of a set of sequential and alternative processes. The method includes the steps of: a) assigning to each process a hardware resource need and time constraint; b) allocating to each process a time-slot having a duration corresponding to the time constraint of the process; c) identifying a branch point at which is decided the execution of one or other of two alternative processes; d) allocating to the two alternative processes a common time-slot; e) assigning to the common time-slot a resource need equal to the larger of the resource needs of the two alternative processes; f) iterating from step c) for each branch point; g) organizing the resulting time-slots in an execution template associated with the task; and h) configuring real-time multitasking system to constrain the execution of the task according to the resource needs assigned to the time slots of the execution template.
