  • Apparatus region-based detection of interference among reordered memory operations in a processor
    Patent number: 5918005
    Abstract: The present invention is an apparatus that maps the memory address space of the computer system into regions, and detects the incorrect execution of a load operation performed earlier than a sequentially preceding (in program order) store operation. The apparatus detects out-of-order load operations, uses a region-based mapping table to keep track of the memory regions accessed by the out-of-order load operations, detects the execution of store operations into regions accessed by out-of-order load operations, and generates a program exception when interference among reordered operations is detected. The invention is applicable to static and dynamic reordering of memory operations.
