GPGPUs have emerged as one of the most widely used throughput processors. Deep multithreading and on-chip cache hierarchy are the two effective designs to achieve high throughput computing in modern GPGPUs. However, excessive multithreading could aggravate the cache contention while conservative multithreading could leave the execution resource under-utilized. Finding a proper design point between...
This paper proposes a novel radar system, namely step-frequency with compressive sampling (SFR-CS), that achieves high target range and speed resolution using significantly smaller bandwidth than traditional step-frequency radar. This bandwidth reduction is accomplished by employing compressive sampling ideas and exploiting the sparseness of targets in the range-speed space.
Quality of Service (QoS) is a desirable feature for mobile ad hoc networks (MANETs) due to the growth of multimedia applications. However, due to the nature of MANETs, it imposes tight constraints on providing QoS assurance for multicast protocol in such networks. In this paper, we investigate the QoS and bandwidth consumption in on demand multicast routing protocol (ODMRP) under 2-hops interference...
In recent research on the Peer-To-Peer (P2P) content delivery system, network coding has been applied as a promising approach to improve the performance of P2P content delivery. Many studies have shown that the live P2P streaming system can take great advantage of network coding. It has also been shown that this technology can also resolves the "last block" problem. Accordingly, P2P seed...
