Abstract: A method accelerates access of a multi-core system to its critical resources, which includes preparing to delete a critical node in a critical resource, separating the critical node from the critical resource, and deleting the critical node if the conditions for deleting the critical node are satisfied. An apparatus includes a confirmation module for the node to be deleted and a deletion module to accelerate access of a multi-core system to its critical resources.
