METHOD AND DEVICE FOR INCREASING SPEED OF ACCESSING CRITICAL RESOURCE BY MULTI-CORE SYSTEM

摘要

A method for increasing speed of accessing critical resource by a multi-core system is disclosed, which includes: preparing to delete a critical node in the critical resource; separating the critical node from the critical resource; deleting the critical node if deleting conditions of the critical node being satisfied. A device for increasing speed of accessing critical resource by a multi-core system is also disclosed in the invention, which includes a module for determining nodes to be deleted and a deleting module. According to the invention, accessing the critical node to be deleted by a core which is accessing would not be effected, and accessing the critical resource in which the critical node was before by other cores would also not be effected. Thereby, it doesn't need to judge whether the critical resource is locked or lock the critical resource when the core accesses the critical resource so as to increase speed of accessing the critical resource by the multi-core system.
