Power consumption is an important design issue of c ~ e n r embedded systems. Data caches consume a signifcant portion of total processor power for data intensive applications. In this p w we propose to utili-e application-specifc information for cache resotrrce allocntion to achieve energv saving, including cache bypassing, the mini-cache and way-pmrition. We use a sopVare MpEG-2 video decoder...

Software implementations of MPEG decompression provide flexibility at low cost but suffer performance problems, including poor cache behavior. For MPEG video, decompressing the video in the implied order does not take advantage of coherence generated by dependent macroblocks and, therefore, undermines the effectiveness of processor caching. In this paper, we investigate the caching performance ...

We study design alternatives for, and describe prototypes and performance of, a scalable and highly available Web server accelerator. The accelerator runs under an embedded operating system and improves Web server performance by caching data. The basic design alternatives include a content router or a TCP router (without content routing) in front of a set of Web cache accelerator nodes, with th...

In this paper we present a cache-performance analysis of an MPEG4 video codec running on a wireless handset Digital BaseBand (DBB) system. We outline the AD6532 DBB system architecture, and the software optimizations used to port an efficient version of an MPEG4 codec to the Blackfin core. Our primary focus is the impact of write-back (WB) versus writethrough (WT) data cache policy on the syste...

Multicast network traac is information with one source node, but many destination nodes. Rather than setting up individual connections between the source node and each destination node, or broadcasting the information to the entire network, multicasting eeciently exploits link capacity by allowing the source node to transmit a small number of copies of the information to mutually-exclusive grou...

SUMMARY Content caching networks like Information-Centric Networking (ICN) are beneficial to reduce the network traffic by storing content data on routers near to users. In ICN, it becomes an important issue to manage system resources, such as storage and network bandwidth, which are influenced by cache characteristics of each cache node. Meanwhile, cache aging techniques based on Time-To-Live ...

Web search engines are composed of a large set of search nodes and a broker machine that feeds them with queries. A location cache keeps minimal information in the broker to register the search nodes capable of producing the top-N results for frequent queries. In this paper we show that it is possible to use the location cache as a training dataset for a standard machine learning algorithm and ...

A cache replacement algorithm called probability based replacement (PBR) is proposed in this paper. The algorithm makes replacement decision based on the byte access probabilities of documents. This concept can be applied to both small conventional web documents and large video documents. The performance of PBR algorithm is studied by both analysis and simulation. By comparing cache hit probabi...

The proxy mechanism widely used in WWW systems offers low-delay data delivery bymeans of “proxy server”. By applying proxy mechanisms to video streaming system, we expect that high-quality and low-delay video distribution can be accomplished without introducing extra load on the system. In addition, it is effective to adapt the quality of cached video data appropriately in the proxy if user req...

Transcoding proxy caching is an important technology for improving the services over Internet, especially in the environment of mobile computing systems. In this paper, we address cooperative determination on cache replacement candidates for transcoding proxies. An original model which determines cache replacement candidates on all candidate nodes in a coordinated fashion with the objective of ...
