ABSTRACT Title of dissertation: RAPID PROTOTYPING OF HIGH PERFORMANCE SIGNAL PROCESSING APPLICATIONS

Advances in embedded systems for digital signal processing (DSP) are enabling many scientific projects and commercial applications. At the same time, these applica-tions are key to driving advances in many important kinds of computing platforms. In this region of high performance DSP, rapid prototyping is critical for faster time-to-market (e.g., in the wireless communications industry) or time-to-science (e.g., in radio astron-omy). DSP system architectures have evolved from being based on application specific integrated circuits (ASICs) to incorporate reconfigurable off-the-shelf field programmable gate arrays (FPGAs), the latest multiprocessors such as graphics processing units (GPUs), or heterogeneous combinations of such devices. We, thus, have a vast design space to ex-plore based on performance trade-offs, and expanded by the multitude of possibilities for target platforms.
