摘要： The application relates to a method and a processor configuration for processor work distribution. The distribution of work among processor cores or units in a processor configuration is normally implemented by global and/or local queues. If several competing cores want to access those queues to add or remove work items a locking mechanism for the queue has to be applied, such as semaphores or locks. However, deadlocks can occur when processes wait for semaphores to get released but nobody releases them. The solution to this problem is a processor configuration (100) comprising dedicated memory areas (111-114) storing the individual processor load status for each processor unit (121-124) and a method for work distribution using the stored individual processor load status thereby not requiring a locking mechanism on the memory.
