Optimizing Performance And Scalability On Hybrid Mpsocs, Hongyuan Ding
Optimizing Performance And Scalability On Hybrid Mpsocs, Hongyuan Ding
Graduate Theses and Dissertations
Hardware accelerators are capable of achieving significant performance improvement. But design- ing hardware accelerators lacks the flexibility and the productivity. Combining hardware accelerators with multiprocessor system-on-chip (MPSoC) is an alternative way to balance the flexibility, the productivity, and the performance. However, without appropriate programming model it is still a challenge to achieve parallelism on a hybrid (MPSoC) with with both general-purpose processors and dedicated accelerators. Besides, increasing computation demands with limited power budget require more energy-efficient design without performance degradation in embedded systems and mobile computing platforms. Reconfigurable computing with emerging storage technologies is an alternative to enable the optimization …
Tincr: Integrating Custom Cad Tool Frameworks With The Xilinx Vivado Design Suite, Brad S. White
Tincr: Integrating Custom Cad Tool Frameworks With The Xilinx Vivado Design Suite, Brad S. White
Theses and Dissertations
The field programmable gate array (FPGA) is appealing as a computational platform because of its ability to be repurposed for a number of different applications and its relatively low design cost. Traditionally, FPGA vendors provide a set of electronic design automation (EDA) tools to assist customers with the implementation of their designs. These tools are necessarily general purpose, and the resulting tool flow does not provide the user much in the way of customization. Frameworks such as RapidSmith and Torc allow for the creation of custom CAD tools that are able to target actual Xilinx FPGA devices. However, they are …
Single Event Mitigation For Aurora Protocol Based Mgt Fpga Designs In Space Environments, Alexander Stanley Harding
Single Event Mitigation For Aurora Protocol Based Mgt Fpga Designs In Space Environments, Alexander Stanley Harding
Theses and Dissertations
This work has extended an existing Aurora protocol for high-speed serial I/O between FPGAs to provide greater fault recovery in the presence of high-energy radiation. To improve on the Aurora protocol, additional resets that affect larger portions of the system were used. Detection for additional error modes that occurred but were not detected by the Aurora protocol was designed. Radiation testing was performed on the Aurora protocol with the additional mitigation hardware. The test gathered large amounts of data on the various error modes of the Aurora protocol and how the additional mitigation circuitry affected the system. The test results …
Fpga Based Bitcoin Mining, Philip Dotemoto
Fpga Based Bitcoin Mining, Philip Dotemoto
Electrical Engineering
This project attempts to implement an open source FPGA based Bitcoin miner on an Altera DE2-115 development board. Bitcoin is an experimental peer-to-peer digital currency based on public key cryptography. The advantages of Bitcoins are that they can be transferred between any two people anywhere in the world, and they do not have the same fees and lack of control associated with traditional methods of currency transfers. The first part of this project focuses on detailing how the Bitcoin network and open source miner work. The second part of the project attempts to improve the performance of the open source …
Real-Time Image Processing On An Fpga For An Intraoperative Goggle Device, Yiyi Zhang
Real-Time Image Processing On An Fpga For An Intraoperative Goggle Device, Yiyi Zhang
McKelvey School of Engineering Theses & Dissertations
The emergence of near-infrared dyes for fluorescence imaging has had a tremendous impact in the medical field. In particular, indocyanin green (ICG) has been widely used for assessing tumor margins during intraoperative procedures. Typically, the dye is intravenously injected into the patient, and after 24 hours the dye is removed from the patient’s body, except where binding between the dye and tumor cells has occurred. This selective binding between ICG and cancerous tissue allows for easy and accurate detection of cancer margins as well as detection of metastasis throughout the patient’s body. In order to detect the binding sites, a …
Power Side-Channel Dac Implementations For Xilinx Fpgas, Daniel Chase Savory
Power Side-Channel Dac Implementations For Xilinx Fpgas, Daniel Chase Savory
Theses and Dissertations
This thesis presents a novel power side-channel DAC (PS-DAC) which is constructed from user-controllable short circuits in FPGAs and which manipulate overall system power through dynamic power dissipation. Alternately, similar PS-DACs are created using shift-register primitives(SRL16E) which manipulate system power through switching logic, for means of comparison with short-circuit-based PS-DACs. PS-DACs are created of various sizes using both short-circuit-based and shift-register-based methods. These PS-DACs are characterized in terms of output linearity,monotonicity, and frequency distortion. Applications explored in this thesis which use PS-DAC technology include a Simple Power Analysis (SPA) side-channel transmitter, and a frequency watermarking application. These applications serve as …
