    摘要: Embodiments of methods and apparatuses for multicast handling in mixed core systems have been described. A method for multicast handling in mixed core systems includes configuring broadcast group registers located in targets. The method also includes receiving a request to create a broadcast group and creating the broadcast group. Finally, the method includes transmitting the broadcast group to targets with broadcast group registers that correspond to the broadcast group.

    摘要: A core block with a highly configurable interface such that the interface of the core can be optimally configured for the system the core is integrated into. In one embodiment the method consists of defining a configurable interface with different configuration options, capturing the specific core configuration through manual entry or through the use of a Graphical User Interface, and providing for software that combines the source description of the core with the configuration data to generate the core with an optimally configured logic and circuit interface.

    摘要: A communication system. One embodiment includes at least two functional blocks, wherein an first functional block communicates with a second functional block by establishing a connection, wherein a connection is a logical state in which data may pass between the first functional block and the second functional block. One embodiment includes a bus coupled to each of the functional blocks and configured to carry a plurality of signals. The plurality of signals includes a connection identifier that indicates a particular connection that a data transfer is part of, and a thread identifier that indicates a transaction stream that the data transfer is part of.

    摘要: The present invention provides for an on-chip communications method with fully distributed control combining a fully-pipelined, fixed-latency, synchronous bus with a two-level arbitration scheme where the first level of arbitration is a framed, time-division-multiplexing arbitration scheme and the second level is a fairly-allocated round-robin scheme implemented using a token-passing mechanism. Both the latency and the bandwidth allocation are software programmable in real-time operation of the system. The present invention also provides for a communications system where access to a shared resource is controlled by the above communications protocol. Access to and from the shared resource from the subsystem is through a bus interface module. The bus interface modules provide a level of indirection between the subsystem to be connected and the shared resource. This allows the decoupling of system performance requirements from subsystem requirements. Communication over the bus is fully memory mapped.
