User generated content (UGC), now with millions of video producers and consumers, is re-shaping the way people watch video and TV. In particular, UGC sites are creating new viewing patterns and social interactions, empowering users to be more creative, and generating new business opportunities. Compared to traditional video-on-demand (VoD) systems, UGC services allow users to request videos from a potentially unlimited selection in an asynchronous fashion. To better understand the impact of UGC services, we have analyzed the world's largest UGC VoD system, YouTube, and a popular similar system in Korea, Daum Videos. In this paper, we first empirically show …
Application Of Ict - I: A Framework For Finding Minimal Test Vectors For Stuck-At-Faults, Azam Beg, S.K. Hasnain
Application Of Ict - I: A Framework For Finding Minimal Test Vectors For Stuck-At-Faults, Azam Beg, S.K. Hasnain
International Conference on Information and Communication Technologies
This paper presents a framework that utilizes Boolean difference theory to find test vectors for stuck-at-fault detection. The framework reads in structural-style Verilog models, and automatically injects single stuck-at-faults (either stuck-at-zero or stuck-at-one) into the models. The simulations are then performed to find minimal sets of test vectors. Using this setup, we conducted experiments on more than 4000 different circuits. The results show that an appreciable savings in test time and effort can be achieved using the method. The same setup can also be used for didactic purposes, specifically for digital design and test courses.
A Graphical Approach To Testing Real-Time Embedded Devices, Steven M. Day
A Graphical Approach To Testing Real-Time Embedded Devices, Steven M. Day
Master's Theses
Software Testing is both a vital and expensive part of the software development lifecycle. Improving the testing process has the potential for large returns. Current testing methodologies used to test real-time embedded devices are examined and the weaknesses in them are exposed. This leads to the introduction of a new graphical testing methodology based on flowcharts. The new approach is both a visual test creation program and an automated execution engine that together frame a new way of testing. The new methodology incorporates flow-based diagrams, visual layouts, and simple execution rules to improve upon traditional testing approaches. The new methodology …

Where Does Your Institution Stand?, Wendell Brase, Mark Askren
Information Technology Services: Publications
Media coverage of sustainability and "green" issues is hard to ignore these days. But less clear is a specific understanding of what this agenda means within higher ed IT organizations. For starters, it's useful to self-assess whether your campus is a leading innovator on all things "green" or satisfied to remain inconspicuous in the middle of the pack. If your institution is trailing but wants to assert a leadership role in environmental stewardship, you need to get engaged to understand what it will take to catch up and how IT can be a leader, not just a contributor, to such …
Image Processing For Multiple-Target Tracking On A Graphics Processing Unit, Michael A. Tanner
Image Processing For Multiple-Target Tracking On A Graphics Processing Unit, Michael A. Tanner
Theses and Dissertations
Multiple-target tracking (MTT) systems have been implemented on many different platforms, however these solutions are often expensive and have long development times. Such MTT implementations require custom hardware, yet offer very little flexibility with ever changing data sets and target tracking requirements. This research explores how to supplement and enhance MTT performance with an existing graphics processing unit (GPU) on a general computing platform. Typical computers are already equipped with powerful GPUs to support various games and multimedia applications. However, such GPUs are not currently being used in desktop MTT applications. This research explores if and how a GPU can …
Application Specific Customization And Scalability Of Soft Multiprocessors, Deepak C. Unnikrishnan
Application Specific Customization And Scalability Of Soft Multiprocessors, Deepak C. Unnikrishnan
Masters Theses 1911 - February 2014
Soft multiprocessor systems exploit the plentiful computational resources available in field programmable devices. By virtue of their adaptability and ability to support coarse grained parallelism, they serve as excellent platforms for rapid prototyping and design space exploration of embedded multiprocessor applications. As complex applications emerge, careful mapping, processor and interconnect customization are critical to the overall performance of the multiprocessor system. In this thesis, we have developed an automated scalable framework to efficiently map applications written in a high-level programmer-friendly language to customizable soft-cores. The framework allows the user to specify the application in a high-level language called Streamit. After …
A Hardware Framework For Yield And Reliability Enhancement In Chip Multiprocessors, Abhisek Pan
A Hardware Framework For Yield And Reliability Enhancement In Chip Multiprocessors, Abhisek Pan
Masters Theses 1911 - February 2014
Device reliability and manufacturability have emerged as dominant concerns in end-of-road CMOS devices. Today an increasing number of hardware failures are attributed to device reliability problems that cause partial system failure or shutdown. Also maintaining an acceptable manufacturing yield is seen as challenge because of smaller feature sizes, process variation, and reduced headroom for burn-in tests. In this project we investigate a hardware-based scheme for improving yield and reliability of a homogeneous chip multiprocessor (CMP). The proposed solution involves a hardware framework that enables us to utilize the redundancies inherent in a multi-core system to keep the system operational in …

Performance Evaluation Of Network-On-Chip Interconnect Architectures, Xinan Zhou
UNLV Theses, Dissertations, Professional Papers, and Capstones
With a communication design style, Network-on-Chips (NoCs) have been proposed as a new Multi-Processor System-on-Chip paradigm. Simulation and functional validation are essential to assess the correctness and performance of the NoC design. In this thesis, a cycle-accurate NoC simulation system in Verilog HDL is developed to evaluate the performance of various NoC architectures. First, a library of NoC components is developed based on an existing design. Each NoC architecture to be evaluated is constructed from the library according to the topology description which specifies the network topology, network size, and routing algorithm. The network performance of four NoC architectures under …

Teaching Software Engineering to professional master’s students is a challenging endeavor, and arguably for the past 20 years, Carnegie Mellon University has been quite successful. Although CMU teaches Software Engineering at sites world-wide and uses different pedagogies, the goal of the curriculum -- to produce world-class software engineers -- remains constant. This paper will discuss two of the most mature versions of Carnegie Mellon’s Software Engineering program -- the main campus program and its “daughter program” at the Silicon Valley Campus. We discuss the programs with respect to the dimensions of curriculum, how students work and learn, how faculty teach, …
