Inter-queue anti-starvation mechanism with dynamic deadlock avoidance in a retry based pipeline

摘要

Methods and apparatus relating to an inter-queue anti-starvation mechanism with dynamic deadlock avoidance in a retry based pipeline are described. In one embodiment, logic may arbitrate between two queues based on various rules. The queues may store data including local or remote requests, data responses, non-data responses, external interrupts, etc. Other embodiments are also disclosed.
