A multithreaded processor and a mechanism and a method for executing one hard real-time task in a multithreaded processor

摘要

The invention relates to a mechanism for executing one Hard Real-Time (HRT) task in a multithreaded processor comprising means for determining the slack time of the HRT task; means for starting the execution of the HRT task; means for verifying if the HRT task requires using a resource that is being used by at least one Non Hard Real-Time (NHRT) task; means for determining the delay caused by the NHRT task; means for subtracting the determined delay from the slack time of the HRT task; means for verifying if the new value of the slack time is lower than a critical threshold; and means for stopping the NHRT tasks.
