    Abstract: To provide for the processing of priority data elements between a host processor and a co- processor that exchange such data elements using a queue, the host processor determines a priority of a data element received from an application. If the priority is higher than a lowest possible priority value, at least one lower priority data element within the queue may be identified and modified thereby temporarily removing it from the queue. When the priority data element is written into the queue a query packet is included that will cause the co-processor to return information regarding a last executed queued data element. Based on the returned information, the host processor can determine one or more unmodified data elements (uniquely corresponding to the one or more modified queued data elements) to be written into the queue in accordance with a sequence of the previously modified queued data elements.

    Abstract translation: 为了提供在主机处理器和使用队列交换这样的数据元素的协处理器之间的优先级数据元素的处理，主处理器确定从应用接收的数据元素的优先级。 如果优先级高于最低可能的优先级值，则可以识别和修改队列内的至少一个较低优先级的数据元素，从而将其临时从队列中移除。 当优先级数据元素被写入队列时，包括查询分组，这将使协处理器返回关于最后执行的排队数据元素的信息。 基于返回的信息，主机处理器可以根据先前修改的排队数据元素的顺序来确定要写入队列的一个或多个未修改数据元素（唯一对应于一个或多个修改后的排队数据元素）。

    Abstract: To provide for the processing of priority data elements between a host processor and a co- processor that exchange such data elements using a queue, the host processor determines a priority of a data element received from an application. If the priority is higher than a lowest possible priority value, at least one lower priority data element within the queue may be identified and modified thereby temporarily removing it from the queue (the co-processor skips processing modified data elements). When the priority data element is written into the queue a query packet is included that will cause the co-processor to return information regarding a last executed queued data element. Based on the returned information, the host processor can determine one or more unmodified data elements (uniquely corresponding to the one or more modified queued data elements) to be written into the queue in accordance with a sequence of the previously modified queued data elements. Thus the pre-empted queued data elements can be restored in the queue in an unmodified form.
