1. A method of notifying a task manager that data is available for processing, the method comprising: generating a first notification signal that is transmitted to the task manager, wherein the notification signal specifies a first offset and a first delta value; storing first data in one or more entries indicated by the first offset and the first delta value in a queue corresponding to a first processing task; generating a second notification signal that is transmitted to the task manager, wherein the notification signal comprises a second offset and a second delta value; storing second data in one or more entries indicated by the second offset and the second delta value in the queue corresponding to the first processing task; receiving the first notification signal and a second notification signal; determining if the first offset and the first delta value can be coalesced with the second offset and the second delta value, and, if so, generating a coalesced offset and a coalesced delta value; and scheduling, by the task manager, processing of at least one of the first data and the second data for the first processing task in a processing cluster array.
