Abstract
Embodiments of the present invention are directed to methods for efficient queue management, and device implementations that incorporate these methods, for systems that include two or more electronic devices that share a queue residing in the memory of one of the two or more electronic devices. In certain embodiments of the present invention, a discard field or bit is included in each queue entry. The bit or field is set to a first value, such as the Boolean value '0,' by a producing device to indicate that the entry is valid, or, in other words, that the entry can be consumed by the consuming device. After placing entries into the queue, the producing device may subsequently remove one or more entries from the queue by setting the discard field or bit to a second value, such as Boolean value '1.' The consuming device removes each entry from the queue, in turn, as the consuming device processes queue entries, discarding, without further processing, those entries with the discard bit or field set to the second value.
