  • Binary translation of self-modifying code
    Patent number: 7107580
    Abstract: A simulator includes a binary translator to translate target code into host instructions to be executed on a host processor. To identify target instructions which may be modified by self-modifying code, the simulator determines whether a target instruction to be translated resides in a writeable page, and if so, inserts a run-time check into a translation cache along with translated instructions corresponding to such target instructions.
    Type: Grant

    Date of Patent: September 12, 2006
    Assignee: Intel Corporation
    Inventors: Yigal Zemach, Alex Skaletsky
  • Exception masking in binary translation
    Patent number: 7000226
    Abstract: Mapping of exception masks between source and target architectures with different numbers of exception masks enables a binary translator to translate code from the source to the target architecture and to determine an appropriate state for the source architecture if an exception is raised when executing the translated code.
