Research ArticleOpen accessIn the abstractHigh Performance Computing on Fast Lock Delay Locked Loop with Low Power State and Simultanoeus Switching Noise ReductionT. S. Karthik, V. Jawahar Senthil KumarProblem statement: In any multimedia processor, controller may consume most of the on-chip memory resources. The memory requirement is directly depends on algorithm shared by different blocks, so leads to failure in the system models. Approach: This study presents the implementation of DLL unit used for memory optimization. Various aspects of the underlying coarse lock detector are explored and modifications … …Journal of Computer Science, Vol. 8, Issue 3 · 6 Jan 2012 · 7,172 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordAn Effective Contention Aware Stable Path Finding Approach to Provide Quality of Service in Mobile Ad hoc NetworksD. S. Thenmozhi, M. RajaramProblem statement: The application of Mobile Ad hoc NETworks (MANETs) has been increasing every day. Most applications that attract interest for use in current wired networks (e.g. video conferencing, on line movies and camera enabled instant messenger) would attract interest for MANETs also. Many applications that use MANETs include multimedia data that require Quality of Service (QoS) support for effective … …Journal of Computer Science, Vol. 7, Issue 3 · 7 Mar 2011 · 6,740 accessesView PDF Cite
