Abstract
Task execution control for a multiprocessor wherein at a time point when a post issue task ends the use of a shared resource, the shared resource is released, another task which is running on another processor is allowed to lock the shared resource, and thereafter the task is made ready. After that, the post procedure is initiated, and thereafter through the high-speed dispatch procedure, the processor is granted first to a task which has failed to lock the shared resource, and the task is prompted to retry to lock the shared resource.
