The present disclosure provides a method for providing Quality of Service (QoS) processing of a plurality of data packets stored in a first memory. The method may include determining a queue of a plurality of queues causing an interrupt using contents of an interrupt status register, the queue comprising address of at least one data packet of the plurality of data packets. The method may further include performing a logical operation between the contents of the interrupt status register and an interrupt mask of a plurality of interrupt masks, the plurality of interrupt masks stored in a second memory. The method may also include processing the plurality of data packets based on the logical operation and incrementing an interrupt mask address pointer stored in a third memory, thereby pointing to another interrupt mask of the plurality of interrupt masks. Of course, many alternatives, variations and modifications are possible without departing from this embodiment.
