“…The ever-growing request of bandwidth in mobile advanced applications, as well as the Digital Divide discrimination, are leading to the development of more and more efficient methodologies for bandwidth optimization. Several techniques have been developed, such as Traffic Shaping (Gringeri, S., 1998), Policy-Based Traffic Management (Conchon, E., 2010, Fangming Z., 2008, Heithecker, S., 2007 and Quality of Service (QoS) (Chang Wook, A., 2004, Huang, J.H., 2006.…”

Smart Applications for the Cultural Heritage are playing an increasingly fundamental role in several fields, ranging from tourism to home entertainment. E/m-Learning systems are also involved, since advanced contents from the Cultural Heritage can be used in History of Art lessons. For instance, teachers can decide to make students enjoy HQ images or videos of masterpieces, accessed from the Internet. In this context, several problems must be considered, among which an appropriate fruition of such data. In this paper, two specific issues are taken into account: firstly, the so called Perceived Quality of Service (PQoS) in case of visual information; secondly, the case is discussed of high-bandwidth demanding contents accessed in realtime, such as HQ streaming videos. An early architecture is finally proposed for the dynamic management of bandwidth release on the basis of content size and duration.

For most SoCs, off-chip DRAM is an important resource that is shared by many heterogeneous function units(FU). To meet different memory access requirements by these FUs, it is crucial that the memory subsystem is capable of providing different Quality of Service(QoS).Due to the nature of DRAM, the available bandwidth greatly depends on the memory access sequence. However, conventional schedulers are not aware of the variable bandwidth. In this paper, a QoS scheduler is proposed by recognizing the inefficiency caused by ongoing memory accesses. The experimental results show that, the scheduler can provide bandwidth guarantee for bandwidth sensitive FUs even in the worst case scenarios. And low latency for latency sensitive FUs can be achieved when the bus is below the saturation point.2009 IEEE International Conference on Networking, Architecture, and Storage 978-0-7695-3741-2/09 $25.00
