  • Method and apparatus for transmitting data in an integrated circuit
    Patent number: 7536496
    Abstract: A method and apparatus for transmitting data between cores residing in an integrated circuit. Data is transmitted by using hubs located between the cores and an arbiter. The arbiter maintains a table that contains all the valid combinations of routing paths between the cores.
    Type: Grant
    Filed: February 28, 2006
    Date of Patent: May 19, 2009
    Assignee: International Business Machines Corporation

  • Method and apparatus for providing bus arbitrations in a data processing system
    Patent number: 6944698
    Abstract: 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.
