Method and system for dynamically shared completion table supporting multiple threads in a processing system |
摘要 |
A method and system for utilizing a completion table in a superscalar processor is disclosed. The method and system comprises providing a plurality of threads to the processor and associating a link list with each of the threads, wherein each entry associated with a thread is linked to a next entry. A method and system in accordance with the present invention implements the completion table as link lists. Each entry in the completion table in a thread is linked to the next entry via a pointer that is stored in a link list. In a second aspect a method of determining the relative order between instructions is provided. A method and system in accordance with the present invention implements a flush mask array which is accessed to determine the relative order of entries in the said completion table. A method and system in accordance with the present invention implements a restore head pointer table to save and restore the state of the pointer of said completion table. |
