A slot reservation method is disclosed. The slot reservation method generates slot reservations in two dimensions to address starvation and to reduce bounce of messages transmitted through an interconnect. An interconnect implemented using the slot reservation method is capable of being scaled to larger network-on-chip implementations.

Anti-starvation and bounce-reduction mechanism for a two-dimensional bufferless interconnect

Methods and apparatus relating to techniques for controlling resource utilization with adaptive routing are described. In one embodiment, an output port for transmission of an incoming message that is to be received at an input port is determined at routing logic. The routing logic selects the output port from a first output port and a second output port based on congestion information that is detected at one or more other routing logic communicatively coupled to the routing logic. The first output port provides a deterministic route for the incoming message and the second output port provides an adaptive route for the incoming message. Other embodiments are also disclosed.

Mechanism to control resource utilization with adaptive routing

An apparatus that includes input ports, input buffers coupled with respective input ports, output ports, and routing control circuitry coupled with the input ports, the input buffers and/or the output ports. The plurality of input buffers and the plurality of output ports, the routing control circuitry to maintain a two-tier priority scheme having at least two queues for prioritizing requests stored in the plurality of input buffers.
