Modeling and simulation of the free electron laser and railgun on an electric Naval surface platformBowlin, Oscar E. 03 1900 (has links)
The Free Electron Laser (FEL) and Rail Gun are electric weapons which will require a significant amount of stored energy for operation. These types of weapons are ideal for use onboard an all-electric ship. An investigation is made of the effects these weapons will have on a proposed electrical system architecture using simulation modeling. Specifically, this thesis identifies possible design weaknesses and shows where further research and modeling is needed in order to ensure the proper integration of these electric weapons onboard an all-electric ship. The integration of these electric weapon systems with the power systems on electric ships will have an impact on naval operations. Several scenarios concerning specific naval missions are investigated using simulation software to understand the impact and limitations on the electric system using these new electric weapons.

The dynamic simultaneous multithreaded processorOrtiz-Arroyo, Daniel 12 December 2002 (has links)
This dissertation investigates diverse techniques to support multithreading in modern
high performance processors. The mechanisms studied expand the architecture of a high
performance superscalar processor to control efficiently the interaction between software-controlled
and hardware-controlled multithreading. Additionally, dynamic speculative
mechanisms are proposed to exploit thread-level-parallelism (TLP) and instruction-level-parallelism
(ILP) on a Simultaneous Multithreading (SMT) architecture.
First, the hybrid multithreaded execution model is discussed. This model
combines software-controlled multithreading with hardware support for efficient context
switching and thread scheduling. A thread scheduling technique called set scheduling is
introduced and its impact on the overall performance is described. An analytical model
of the hybrid multithreaded execution is developed and validated by simulation. Through
stochastic simulation, we find that the application of the hybrid multithreaded execution
model results in higher processor utilization than traditional software-controlled
multithreading.
Next, in the main part of this dissertation, a new architecture is proposed: the
Dynamic Simultaneous Multithreading (DSMT) processor. In this architecture, multiple
threads are identified and created speculatively at runtime without compiler help.
Subsequently, a SMT processor core executes those threads. The performance of a
DSMT processor was evaluated with a new execution-driven simulator developed
specifically for the purpose. Our experimental results based on simulation show that
DSMT architecture has very good potential to improve SMT processor's performance
when there is only a single task available for execution. / Graduation date: 2003

Reusable OpenCL FPGA InfrastructureChin, Stephen Alexander 25 July 2012 (has links)
OpenCL has emerged as a standard programming model for heterogeneous systems. Recent work combining OpenCL and FPGAs has focused on high-level synthesis. Building a complete OpenCL FPGA system requires more than just high-level synthesis. This work introduces a reusable OpenCL infrastructure for FPGAs that complements previous work and specifically targets a key architectural element - the memory interface. An Aggregating Memory Controller that aims to maximize bandwidth to external, large, high-latency, high-bandwidth memories and a template Processing Array with soft-processor and hand-coded hardware elements are designed, simulated, and implemented on an FPGA. Two micro-benchmarks were run on both the soft-processor elements and the hand-coded hardware elements to exercise the Aggregating Memory Controller. The micro-benchmarks were simulated as well as implemented in a hardware prototype. Memory bandwidth results for the system show that the external memory interface can be saturated and the high-latency can be effectively hidden using the Aggregating Memory Controller.
