  • Processing of self-modifying code in multi-address-space and multi-processor systems
    Patent number: 7822924
    Abstract: A method and system of storing to an instruction stream with a multiprocessor or multiple-address-space system is disclosed. A central processing unit may cache instructions in a cache from a page of primary code stored in a memory storage unit. The central processing unit may execute cached instructions from the cache until a serialization operation is executed. The central processing unit may check in a message queue for a notification message indicating potential storing to the page. If the notification message is present in the message queue, cached instructions from the page are invalidated.
