ABSTRACT:
Method and means for controlling the execution sequence of a first sequence of modules in a first task. The first sequence of modules are linked to one another and have at least one sequence of execution. The method stores in each of the first sequence of modules a skip value representing which of subsequent modules to execute. The method executes the first of the first sequence of said modules, and then executes the next of the modules indicated by the skip value. Conservation of processor bandwidth is accomplished by avoiding the loading of modules which will not be executed.Method and means are further provided for simultaneous activation/deactivation of a set of tasks by a processor, each of the tasks normally executed in a sequential fashion by one or more processors. A list of tasks to be activated/deactivated is stored, including the timing relationship for the activation process. The list is then implemented as frame numbers for activation and requested state in the actual task list. The executing processor compares the requested state to the actual state for each task, and if different, compares the value of the activation frame with the current frame. If the current frame equals or exceeds the activation frame, then the requested active state is transferred to the actual state.
