  • System-on-chip and data arbitration method thereof
    Patent number: 8819310
    Abstract: A system-on-a-chip semiconductor device comprises a first master device configured to issue a request having a transaction ID, a plurality of slave devices configured to provide data in response to the request, and an interconnector configured to include a slave interface for providing the request to one or more master interfaces and for supplying response data to the first master device based on operation characteristics of the first master. An arbitration method of an interconnector transferring a plurality of response data provided from a plurality of slave devices to a master device comprises selecting one of a plurality of arbitration modes based on operation characteristics of the master device; and transferring the response data in the order determined by transfer priority corresponding to the selected arbitration mode.

  • Interface Devices And Systems Including The Same
    Publication number: 20120117286
    Abstract: An interface device includes a transaction management unit, a buffer unit and a selection circuit. The transaction management unit selectively splits a transaction of a master device into a first sub-transaction and at least one remaining sub-transaction based on a size of the transaction. The buffer unit stores the remaining sub-transaction. The selection circuit selects one of the first sub-transaction and an output of the buffer unit in response to a select control signal.
