High performance scalable image compression with EBCOT

by David Taubman - IEEE Trans. Image Processing , 2000
"... A new image compression algorithm is proposed, based on independent Embedded Block Coding with Optimized Truncation of the embedded bit-streams (EBCOT). The algorithm exhibits state-of-the-art compression performance while producing a bit-stream with a rich feature set, including resolution and SNR ..."

Route Packets, Not Wires: On-Chip Interconnection Networks

by William J. Dally, Brian Towles , 2001
"... Using on-chip interconnection networks in place of ad-hoc global wiring structures the top level wires on a chip and facilitates modular design. With this approach, system modules (processors, memories, peripherals, etc...) communicate by sending packets to one another over the network. The structur ..."
Abstract - Cited by 885 (10 self) - Add to MetaCart
. The structured network wiring gives well-controlled electrical parameters that eliminate timing iterations and enable the use of high-performance circuits to reduce latency and increase bandwidth. The area overhead required to implement an on-chip network is modest, we estimate 6.6%. This paper introduces

Design and Evaluation of a Compiler Algorithm for Prefetching

by Todd C. Mowry, Monica S. Lam, Anoop Gupta - in Proceedings of the Fifth International Conference on Architectural Support for Programming Languages and Operating Systems , 1992
"... Software-controlled data prefetching is a promising technique for improving the performance of the memory subsystem to match today's high-performance processors. While prefetching is useful in hiding the latency, issuing prefetches incurs an instruction overhead and can increase the load on the ..."

A case for redundant arrays of inexpensive disks (RAID)

by David A Patterson, Garth Gibson, Randy H Katz , 1988
"... Increasing performance of CPUs and memories will be squandered if not matched by a similar peformance increase in IO. While the capacity of Smgle Large Expenstve D&T (SLED) has grown rapuily, the performance rmprovement of SLED has been modest Redundant Arrays of Inexpensive Disks (RAID), based ..."

TaintDroid: An Information-Flow Tracking System for Realtime Privacy Monitoring on Smartphones

by William Enck, Landon P. Cox, Jaeyeon Jung, et al. , 2010
"... Today’s smartphone operating systems fail to provide users with adequate control and visibility into how third-party applications use their private data. We present TaintDroid, an efficient, system-wide dynamic taint tracking and analysis system for the popular Android platform that can simultaneous ..."
Abstract - Cited by 527 (26 self) - Add to MetaCart
simultaneously track multiple sources of sensitive data. TaintDroid’s efficiency to perform real-time analysis stems from its novel system design that leverages the mobile platform’s virtualized system architecture. TaintDroid incurs only 14 % performance overhead on a CPU-bound micro-benchmark with little

Active Messages: a Mechanism for Integrated Communication and Computation

by Thorsten Von Eicken, David E. Culler, Seth Copen Goldstein, Klaus Erik Schauser , 1992
"... The design challenge for large-scale multiprocessors is (1) to minimize communication overhead, (2) allow communication to overlap computation, and (3) coordinate the two without sacrificing processor cost/performance. We show that existing message passing multiprocessors have unnecessarily high com ..."

PVS: A Prototype Verification System

by S. Owre, J. M. Rushby, N. Shankar - CADE , 1992
"... PVS is a prototype system for writing specifications and constructing proofs. Its development has been shaped by our experiences studying or using several other systems and performing a number of rather substantial formal verifications (e.g., [5,6,8]). PVS is fully implemented and freely available. ..."

Dynamic source routing in ad hoc wireless networks

by David B. Johnson, David A. Maltz - Mobile Computing , 1996
"... An ad hoc network is a collection of wireless mobile hosts forming a temporary network without the aid of any established infrastructure or centralized administration. In such an environment, it may be necessary for one mobile host to enlist the aid of other hosts in forwarding a packet to its desti ..."

destination, due to the limited range of each mobile host’s wireless transmissions. This paper presents a protocol for routing in ad hoc networks that uses dynamic source routing. The protocol adapts quickly to routing changes when host movement is frequent, yet requires little or no overhead during periods

Xen and the art of virtualization

by Paul Barham, Boris Dragovic, Keir Fraser, Steven Hand, Tim Harris, Alex Ho, Rolf Neugebauer, Ian Pratt, Andrew Warfield - IN SOSP , 2003
"... Numerous systems have been designed which use virtualization to subdivide the ample resources of a modern computer. Some require specialized hardware, or cannot support commodity operating systems. Some target 100 % binary compatibility at the expense of performance. Others sacrifice security or fun ..."

instances simultaneously on a modern server. The virtualization approach taken by Xen is extremely efficient: we allow operating systems such as Linux and Windows XP to be hosted simultaneously for a negligible performance overhead — at most a few percent compared with the unvirtualized case. We

Range-Free Localization Schemes for Large Scale Sensor Networks

by Tian He, Chengdu Huang, Brain M. Blum, John A. Stankovic, Tarek Abdelzaher , 2003
"... Wireless Sensor Networks have been proposed for a multitude of location-dependent applications. For such systems, the cost and limitations of hardware on sensing nodes prevent the use of range-based localization schemes that depend on absolute point-to-point distance estimates. Because coarse accura ..."
Abstract - Cited by 525 (8 self) - Add to MetaCart
