System-On-A-Chip (Soc) Based Hardware Acceleration In Register Transfer Level (Rtl) Design, Xinwei Niu
System-On-A-Chip (Soc) Based Hardware Acceleration In Register Transfer Level (Rtl) Design, Xinwei Niu
FIU Electronic Theses and Dissertations
Today, modern System-on-a-Chip (SoC) systems have grown rapidly due to the increased processing power, while maintaining the size of the hardware circuit. The number of transistors on a chip continues to increase, but current SoC designs may not be able to exploit the potential performance, especially with energy consumption and chip area becoming two major concerns. Traditional SoC designs usually separate software and hardware. Thus, the process of improving the system performance is a complicated task for both software and hardware designers. The aim of this research is to develop hardware acceleration workflow for software applications. Thus, system performance can …

Recently, energy efficiency or green IT has become a hot issue for many IT infrastructures as they attempt to utilize energy-efficient strategies in their enterprise IT systems in order to minimize operational costs. Networking devices are shared resources connecting important IT infrastructures, especially in a data center network they are always operated 24/7 which consume a huge amount of energy, and it has been obviously shown that this energy consumption is largely independent of the traffic through the devices. As a result, power consumption in networking devices is becoming more and more a critical problem, which is of interest for …
Scheduling Medical Application Workloads On Virtualized Computing Systems, Javier Delgado
Scheduling Medical Application Workloads On Virtualized Computing Systems, Javier Delgado
FIU Electronic Theses and Dissertations
This dissertation presents and evaluates a methodology for scheduling medical application workloads in virtualized computing environments. Such environments are being widely adopted by providers of “cloud computing” services. In the context of provisioning resources for medical applications, such environments allow users to deploy applications on distributed computing resources while keeping their data secure. Furthermore, higher level services that further abstract the infrastructure-related issues can be built on top of such infrastructures. For example, a medical imaging service can allow medical professionals to process their data in the cloud, easing them from the burden of having to deploy and manage these …
On-Line Real-Time Service-Oriented Task Scheduling Using Tuf, Shuo Liu, Gang Quan, Shangping Ren
On-Line Real-Time Service-Oriented Task Scheduling Using Tuf, Shuo Liu, Gang Quan, Shangping Ren
Electrical and Computer Engineering Faculty Publications
We present our approach to real-time service-oriented scheduling problems with the objective of maximizing the total system utility. Different from the traditional utility accrual scheduling problems that each task is associated with only a single time utility function (TUF), we associate two different TUFs—a profit TUF and a penalty TUF—with each task, to model the real-time services that not only need to reward the early completions but also need to penalize the abortions or deadline misses. The scheduling heuristics we proposed in this paper judiciously accept, schedule, and abort real-time services when necessary to maximize the accrued utility. Our extensive …
Quality Of Experience Evaluation Of Voice Communication: An Affect-Based Approach, Abhishek Bhattacharya, Wanmin Wu, Zhenya Wang
Quality Of Experience Evaluation Of Voice Communication: An Affect-Based Approach, Abhishek Bhattacharya, Wanmin Wu, Zhenya Wang
School of Computing and Information Sciences
Voice communication systems such as Voice-over IP (VoIP), Public Switched Telephone Networks, and Mobile Telephone Networks, are an integral means of human tele-interaction. These systems pose distinctive challenges due to their unique characteristics such as low volume, burstiness and stringent delay/loss requirements across heterogeneous underlying network technologies. Effective quality evaluation methodologies are important for system development and refinement, particularly by adopting user feedback based measurement. Presently, most of the evaluation models are system-centric (Quality of Service or QoS-based), which questioned us to explore a user-centric (Quality of Experience or QoE-based) approach as a step towards the human-centric paradigm of system …
