Implementation of a Trusted I/O Processor on a Nascent SoC-FPGA Based Flight Controller for Unmanned Aerial Systems
(Virginia Tech, 2018-03-26)
Unmanned Aerial Systems (UAS) are aircraft without a human pilot on board. They are comprised of a ground-based autonomous or human operated control system, an unmanned aerial vehicle (UAV) and a communication, command and ...
Enhancing Trust in Autonomous Systems without Verifying Software
(Virginia Tech, 2019-06-12)
The complexity of the software behind autonomous systems is rapidly growing, as are the applications of what they can do. It is not unusual for the lines of code to reach the millions, which adds to the verification ...
A Development Platform to Evaluate UAV Runtime Verification Through Hardware-in-the-loop Simulation
(Virginia Tech, 2020-06-17)
The popularity and demand for safe autonomous vehicles are on the rise. Advances in semiconductor technology have led to the integration of a wide range of sensors with high-performance computers, all onboard the autonomous ...
A Custom Computing Machine Solution for Simulation of Discretized Domain Physical Systems
(Virginia Tech, 1996-06-05)
This thesis describes the implementation of a two-dimensional heat transfer simulation system using a Splash-2 Custom Computing Machine (CCM). This application was implemented as a proof of concept for utilizing CCMs in ...
Making Radios with GReasy: GNU Radio With FPGAs Made Easy
(Virginia Tech, 2014-08-29)
Radio technology is rapidly evolving and as processing capabilities and algorithms become more complex, the need for alternative compilation and user interface abstraction increases. Field Programmable Gate Array (FPGA) ...
Hybrid FPGA and GPP Implementation of IEEE 802.15.4 Physical Layer
(Virginia Tech, 2012-07-30)
In this thesis, two different cases of hybrid IEEE 802.15.4 PHY (Physical Layer) implementation are explored. The first case is an FPGA implementation of IEEE 802.15.4 PHY on the Xilinx Spartan-3A DSP FPGA of USRP N210. ...
A Multiplexed Memory Port for Run Time Reconfigurable Applications
(Virginia Tech, 1999-12-13)
Configurable computing machines (CCMs) are available as plug in cards for standard workstations. CCMs make it possible to achieve computing feats on workstations that were previously only possible with super computers. ...
A Zynq-based Cluster Cognitive Radio
(Virginia Tech, 2014-07-25)
Traditional hardware radios provide very rigid solutions to radio problems. Intelligent software defined radios, also known as cognitive radios, provide flexibility and agility compared to hardware ...
Symbol Timing and Coarse Classification of Phase Modulated Signals on a Standalone SDR Platform
(Virginia Tech, 2010-10-06)
The Universal Classifier Synchronizer (UCS) is a Cognitive Radio system/sensor that can detect, classify, and extract the relevant parameters from a received signal to establish physical layer communications using the ...
Coarse Radio Signal Classifier on a Hybrid FPGA/DSP/GPP Platform
(Virginia Tech, 2009-12-07)
The Virginia Tech Universal Classifier Synchronizer (UCS) system can enable a cognitive receiver to detect, classify and extract all the parameters needed from a received signal for physical layer demodulation and configure ...
