    摘要： A data processing system includes a central processing unit (CPU) in communication with a system memory. Within the system memory, there is stored legacy code that does not utilize the full features of the CPU. The data processing system also includes a code-optimizing coprocessor in communication with the CPU and the system memory. Control logic within the code-optimizing coprocessor causes the code-optimizing coprocessor to generate optimized code from the legacy code at the same time the CPU executes the legacy code, such that the optimized code is tailored according to the CPU. After the code-optimizing coprocessor has generated at least some optimized code, the code-optimizing coprocessor causes the CPU to automatically utilize at least some optimized code in lieu of at least some of the legacy code.

    摘要： A system and method for providing on-chip voltage distribution and regulation. In accordance with the system of the present invention, an IC chip includes a source voltage plane having a source supply rail for supplying power to the IC chip and a source ground rail for sinking power supplied therefrom. At least one intermediate ground rail is connected between the source supply rail and the source ground rail to divide the source voltage plane into multiple intermediate voltage planes. The intermediate ground rail serves as a supply rail for a subsequent intermediate voltage plane such that the intermediate voltage planes are series-connected.

    摘要： A method and apparatus for providing bus arbitrations in a multiprocessor system is disclosed. A computer system includes a common bus that is shared by multiple cores, such as processors. A history of bus requests for the common bus made by the cores is stored in a bus request history table. In response to bus request made by the cores, the common bus is arbitrated according to information stored in the bus request history table by an arbiter.
