  • Architecture for generating intermediate representations for program code conversion
    Patent number: 8104027
    Abstract: An improved architecture for a program code conversion apparatus and method for generating intermediate representations for program code conversion. The program code conversion apparatus determines which types of IR nodes to generate in an intermediate representation (IR) of subject code (10) to be translated. Depending upon the particular subject and target computing environments involved in the conversion, the program code conversion apparatus utilizes either base nodes, complex nodes, polymorphic nodes, and architecture specific nodes, or some combination thereof, in generating the intermediate representation.

  • Memory consistency protection in a multiprocessor computing system
    Patent number: 7895407
    Abstract: A method and apparatus to protect memory consistency in a multiprocessor computing system are described, in particular relating to program code conversion such as dynamic binary translation. The exemplary system provides a memory, processors and a controller/translator unit (CTU) arranged to convert subject code into at least first and second target code portions executable on the processors. The CTU comprises an address space allocation unit to provide virtual address space regions and direct the target code portions to access the memory therethough; a shared memory detection unit to detect a request to access a shared memory area, accessible by both target code portions, and to identify at least one group of instructions in the first target code portion which access the shared memory area; and a memory protection unit to selectively apply memory consistency protection in relation to accesses to the shared memory area by the identified group of instructions.
