RANDOM EARLY DROP BASED PROCESSING CIRCUIT AND METHOD FOR TRIGGERING RANDOM EARLY DROP BASED OPERATION ACCORDING TO AT LEAST TRIGGER EVENT GENERATED BASED ON SOFTWARE PROGRAMMABLE SCHEDULE

摘要

A random early drop (RED) based processing circuit includes a scheduler, an RED-based decision logic and a controller. The scheduler generates a trigger event according to an RED-based operation schedule. The scheduler is coupled to a software interface, and the RED-based operation schedule in the scheduler is programmed via the software interface. The RED-based decision logic performs at least a first RED-based operation to generate a first RED decision accordingly. The controller receives at least the trigger event, and triggers the RED-based decision logic to perform the first RED-based operation according to at least the trigger event.
