  • 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.

  • 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.

  • Clocking scheme for ASIC
    Patent number: 6552590
    Abstract: A clock scheme for a system on a chip wherein integral sub-multiples of a system clock have positive edges on odd-numbered positive edges of the system clock and negative edges on even-numbered positive edges Data transfer between blocks of different frequencies is controlled by a state machine of the higher frequency block and can be achieved without elastic buffers and/or synchronizers.

  • 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.
