Abstract: Processor-based system hybrid ring bus interconnects, and related devices, systems, and methods are disclosed. In one embodiment, a processor-based system hybrid ring bus interconnect is provided. The processor-based system hybrid ring bus interconnect includes multiple ring buses, each having a bus width and configured to receive bus transaction messages from a requester device(s). The processor-based system hybrid ring bus interconnect also includes an inter-ring router(s) coupled to the ring buses. The inter-ring router(s) is configured to dynamically direct bus transaction messages among the ring buses based on bandwidth requirements of the requester device(s). Thus, less power is consumed than by a crossbar interconnect due to simpler switching configurations. Further, the inter-ring router(s) allows for provision of multiple ring buses that can be dynamically activated and deactivated based on bandwidth requirements. This provides conservation of power when full bandwidth requirements on the processor-based system hybrid ring bus interconnect are not required.

Abstract: Methods and apparatus for transaction ordering to avoid bus deadlocks are provided. In an exemplary method, custom routing rules for data transport are defined for data transport between a plurality of masters and a plurality of slaves via a plurality of interconnects, based on a network topology and traffic profile. In an example, the customized rule allows a request address to arbitrate in a first phase of arbitration at a first interconnect in the plurality of interconnects prior to receiving write data associated with the request address at a second interconnect in the plurality of interconnects, and does not allow the request address to arbitrate during a subsequent second phase of arbitration unless the request address beats other competing address requests.
