发明名称 Method and Apparatus for Handling Multiple Memory Requests Within a Multiprocessor System
摘要 A method for handling multiple memory requests within a multi-processor system is disclosed. A lock control section is initially assigned to a data block within a system memory. In response to a request for accessing the data block by a processing unit, a determination is made whether or not the lock control section of the data block has been set. If the lock control section has been set, another determination is made whether or not the requesting processing unit is located beyond a predetermined distance from a memory controller. If the requesting processing unit is located beyond a predetermined distance from the memory controller, the requesting processing unit is invited to perform other functions; otherwise, the number of the requesting processing unit is placed in a queue table. However, if the lock control section has not been set, the lock control section of the data block is set, and the access request is allowed.
