  • Automatic generation of interconnect logic components
    Patent number: 6877145
    Abstract: A program tool automatically generating interconnect logic for a system-on-a-chip is based on a library of operational cores and on a architecture which requires all data exchange between cores to proceed via shared memory, which may be ‘off-chip’. The architecture includes a data aggregation technique for access to memory with successive levels of arbitration.
    Type: Grant

    Date of Patent: April 5, 2005
    Assignee: 3Com Corporation
    Inventors: Sean Boylan, Derek Coburn, Tadhg Creedon, Denise De Paor, Vincent Gavin, Kevin J Hyland, Suzanne M Hughes, Kevin Jennings, Mike Lardner, Brendan Walsh
  • Asic system architecture including data aggregation technique
    Patent number: 6718411
    Abstract: An architecture for a system on a chip wherein functional cores have wrappers for compatibility with a common bus system and the bus system includes aggregators for bus transactions of different speeds and/or bus widths.

  • Key based register locking mechanism
    Publication number: 20030167400
    Abstract: A key based locking system for guarding against improper or invalid access to internal registers of a core. Two key values are held in at least one lock register and sequential writes of the first and second keys within a predetermined period are required to unlock access to a protected register. Access to the protected register may then be permitted for the rest of the clock cycle, or alternatively may be permitted until a lock command is received.

  • Data bus system including posted reads and writes
    Publication number: 20020184453
    Abstract: A data bus system in which a read or write transaction includes an identification of the initiator of the transaction and optionally an identification of the transaction as a number in a cyclic progression and optionally a request for an acknowledgement.
