Abstract
Systems and methods described herein are directed to solutions for NoC interconnects that provide end-to-end uniform- and weighted-fair allocation of resource bandwidths among various contenders. The example implementations are fully distributed and involve tagging the messages with meta-information when the messages are injected in the interconnection network. Example implementations may involve routers using various arbitration phases, and making local arbitration decisions based on the meta-information of incoming messages. The meta-information can be of various types based on the number of router arbitration phases, and the desired level of sophistication.
