Power Efficient High Temperature Asynchronous Microcontroller Design, Nathan William Kuhns
Power Efficient High Temperature Asynchronous Microcontroller Design, Nathan William Kuhns
Graduate Theses and Dissertations
There is an increasing demand for dependable and efficient digital circuitry capable of operating in high temperature environments. Extreme temperatures have adverse effects on traditional silicon synchronous systems because of the changes in delay and setup and hold times caused by the variances in each device’s threshold voltage. This dissertation focuses on the design of the major functionality of an asynchronous 8051 microcontroller in Raytheon’s high temperature Silicon Carbide process, rated for operation over 300ºC. The microcontroller is designed in NULL Convention Logic, for which the traditional bus architecture used for data transfer would consume a large amount of power. …
Just In Time Assembly (Jita) - A Run Time Interpretation Approach For Achieving Productivity Of Creating Custom Accelerators In Fpgas, Sen Ma
Graduate Theses and Dissertations
The reconfigurable computing community has yet to be successful in allowing programmers to access FPGAs through traditional software development flows. Existing barriers that prevent programmers from using FPGAs include: 1) knowledge of hardware programming models, 2) the need to work within the vendor specific CAD tools and hardware synthesis. This thesis presents a series of published papers that explore different aspects of a new approach being developed to remove the barriers and enable programmers to compile accelerators on next generation reconfigurable manycore architectures. The approach is entitled Just In Time Assembly (JITA) of hardware accelerators. The approach has been defined …
Data Integrity Verification In Cloud Computing, Katanosh Morovat
Data Integrity Verification In Cloud Computing, Katanosh Morovat
Graduate Theses and Dissertations
Cloud computing is an architecture model which provides computing and storage capacity as a service over the internet. Cloud computing should provide secure services for users and owners of data as well. Cloud computing services are a completely internet-based technology where data are stored and maintained in the data center of a cloud provider. Lack of appropriate control over the data might incur several security issues. As a result, some data stored in the cloud must be protected at all times. These types of data are called sensitive data. Sensitive data is defined as data that must be protected against …
Designing Customizable Network-On-Chip With Support For Embedded Private Memory For Multi-Processor System-On-Chips, Azad Fakhari
Designing Customizable Network-On-Chip With Support For Embedded Private Memory For Multi-Processor System-On-Chips, Azad Fakhari
Graduate Theses and Dissertations
The computer industry's transition to multiprocessor systems on chip (MPSoC) architectures is increasing the need for new scalable high-bandwidth on-chip communication
backbones. Network-on-Chip (NoC) interconnects are gaining interest for serving as the on-chip communication infrastructure. The most important issues to be considered in designing a NoC are topology, routing algorithm, flow control, and buffering and also the trade-offs between performance, power, and area.
This research proposes a custom-designed NoC specifically for MPSoCs on FPGAs. The proposed design allows the communication infrastructure to seamlessly scale as the numbers of processors within the chip increases. The design adds a new level of …
The Use Of Complexity Theory And Strange Attractors To Understand And Explain Information System Development, Arthur P. Tomasino
The Use Of Complexity Theory And Strange Attractors To Understand And Explain Information System Development, Arthur P. Tomasino
2013
In spite of the best efforts of researchers and practitioners, Information Systems (IS) developers are having problems "getting it right". IS developments are challenged by the emergence of unanticipated IS characteristics undermining managers ability to predict and manage IS change. Because IS are complex, development formulas, best practices or development guides simply will not work. The difficulties in these system developments stem from the complexity of IS arising from the inter-relationship, interaction, and interconnectivity of the elements in the system and its environment. This research uses complexity concepts to help solve the problem with IS development and explain why so …
