  • Address generation interlock resolution under runahead execution
    Patent number: 7194604
    Abstract: Disclosed is a method and apparatus providing a microprocessor the ability to reuse data cache content fetched during runahead execution. Said data is stored and later retrieved based upon the instruction address of an instruction which is accessing the data cache. The reuse mechanism allows the reduction of address generation interlocking scenarios with the ability to self-correct should the stored values be incorrect due to subtleties in the architected state of memory in multiprocessor systems.
