Universal employment of modern graphics hardware by the example of the optimization of a speech recognition system

May 24th, 2006

In this masters thesis by Christian Fenzl (accomplished at the University of Applied Sciences in Darmstadt), an easy to use framework is implemented with additional demos to show the main concepts of gpgpu. Furthermore, a demo implementation is included which calculates scores on feature vectors used in a speech recognition system (about 12 times faster than an equivalent cpu implementation). An application with several demos using the framework including the fully documented source code (English) and the paper itself (German) is available. The framework code is recommended especially for gpgpu beginners to look into the OpenGL and DirectX code which shows how gpgpu programs can be developed.
