An Adaptive Recompilation Framework For Rotor And Architectural Support For Online Program Instrumentation
(Indian Institute of Science, 2005-12-07)Although runtime systems and the dynamic compilation model have revolutionized the process of application development and deployment, the associated performance overheads continue to be a cause for concern and much research. ... -
Alternative interleaving schemes for interleaved orthogonal frequency division multiplexing
Interleaved OFDM was proposed as an effective solution for improving code rate over slowly varying channels, without affecting the Peak-Average Power Ratio. The system was proposed with a particular interleaving scheme. In ... -
Approximation algorithms for the K- MST problem
Given a graph GGG on nnn vertices, the kkk-MST optimization problem is to find a tree spanning at least kkk vertices of GGG such that the cost of the tree is minimized over all such possible trees. The main contribution ... -
Codes closed under arbitrary abelian group of permutations
Discrete Fourier Transform (DFT) is a widely used tool in the field of electrical engineering. In the name of Mattson-Solomon polynomials, DFT was used in the context of linear cyclic codes in the early days of coding ... -
Combinatorial algorithms for determinant based problems
The thesis started with the early history and development of the theory of determinants. All the important results up to the 1880s were presented through a computing perspective. Pfaffians are closely related to determinants; ... -
Compressed domain analysis of video sequences
Digital video compression has become an essential part of day?to?day life due to a wide variety of applications, including video delivery over the Internet, television broadcasting, video streaming, video conferencing, as ... -
Delayless adaptive IFIR structures and algorithms
Adaptive Filtering (AF) [1], [2] is used in a variety of applications such as system identification, channel equalization, active noise cancellation, and echo cancellation. Over the years, significant research efforts have ... -
Design and implementation of real-time scheduling schemes for genral purpose operating systems
In recent years, we have seen proliferation of computation-intensive, time-critical applications like real-time video, audio, IP-based telecommunication and so on. These applications offer value-added, nice-to-have features ... -
Design of electronic exchanges through decomposition
Decomposition-Based Approaches for Clearing Electronic Exchanges Electronic marketplaces have emerged in recent times as the backbone of important e-commerce and e-business applications to create efficient markets for ... -
Fault tolerant locking for shared disk filesystems
Shared disk files ystems are crucial for providing direct, shared and high performance file system access on top of raw block based Storage Area Networks. One of the key components of a shared disk file system is a ... -
Fault-tolerant distributed algorithms for reconfiguration of rings using management tokens
In this thesis, we propose two algorithms using slightly different approaches to detect failures in a ring, and to reconfigure the ring using a combination of multithreading and management tokens which circulate around the ... -
Integrated Scheduling For Clustered VLIW Processors
(Indian Institute of Science, 2005-11-25)Clustered architecture processors are preferred for embedded systems because centralized register file architectures scale poorly in terms of clock rate, chip area, and power consumption. Scheduling for clustered architectures ... -
Investigation on architectural elements of network processors
Increasing network speeds have placed enormous burden on the processing requirements, and the processors are expected to carry out a variety of tasks. Network Processors (NP) is the blanket name given to the processors ... -

Kernel Methods Fast Algorithms and real life applications
(Indian Institute of Science, 2005-02-08)Support Vector Machines (SVM) have recently gained prominence in the field of machine learning and pattern classification (Vapnik, 1995, Herbrich, 2002, Scholkopf and Smola, 2002). Classification is achieved by finding a ... -
Localization methods for correlated spatially distributed sources
Modeling of sources as point in nature is a very idealistic modeling in array processing. There have been a number of distributed source models proposed in the literature. This work is based on one of these models. It tries ... -
Modeling and analysis of adaptive window controlled randomly arriving file transfers in Internets
The Internet carries predominantly elastic traffic generated by applications such as email, web transfers, and file transfers, and the bandwidth sharing between such sessions is controlled by the Transmission Control ... -
Optimal routing and rate allocation problems in packet networks with QoS support
This thesis explores some of the issues that arise in the provisioning of Quality of Service (QoS) guarantees to applications in the Internet. In order to meet the QoS requirements of connections, the Internet needs to be ... -
Performance analysis of resource allocation schemes in cellular systems
In this thesis, we study the performance of cellular networks under various resource allocation schemes. Radio resources in cellular networks need to be managed efficiently in order to achieve good system performance. In ... -
Performance enhancement through operator caching in reconfigurable architectures
The requirement for computing power has been growing at a faster rate than the growth in compute performance. High-performance designs have increasingly been mapped to expensive Application Specific Integrated Circuit ...
