| I am a Ph.D candidate in the Dynamic Graphics Project lab at the University of Toronto. I completed a BASc in Honours Computer Engineering from the University of Waterloo in May 2005 and an MSc in Computer Science from the University of Toronto in October 2006. My research interests are realistic image synthesis, high-performance rendering using commodity graphics hardware and methods for real-time fluid simulation and animation. My supervisor is Dr. Eugene Fiume. I completed an internship at MSR Redmond in 2008 working on interactive illumination effects under the supervision of Dr. John Snyder. I will be conducting research at Disney Research Zurich as an intern during the summer of 2009 with Dr. Wojciech Jarosz. |

High-Performance Double-Precision Cosine GenerationDerek Nowrouzezahrai, Brian Decker, and William Bishop AbstractThe trigonometric cosine function plays an important role in communication systems, digital signal processing systems, and graphical systems. This paper presents a technique for generating the cosine of an angle that is more computationally efficient than the CORDIC algorithm and its many variants for double-precision floating point calculations. A hardware design implementation of the cosine generator has been developed. Simulation results for an Altera Stratix II FPGA implementation indicate that the hardware design is both more efficient and more precise than previous published implementations.
