1. FPGA based data acquistion and digital pulse processing for PET and SPECT
Abstract : The most important aspects of nuclear medicine imaging systems such as Positron Emission Tomography (PET) or Single Photon Emission Computed Tomography (SPECT) are the spatial resolution and the sensitivity (detector efficiency in combination with the geometric efficiency). Considerable efforts have been spent during the last two decades in improving the resolution and the efficiency by developing new detectors. READ MORE

2. Custom Designed Digital Signal Processors Using Bit-Serial Arithmetic
Abstract : This thesis presents two prime contributions. First, digital filters for both intermediate and base band filtering for mobile communication are presented. Second, a local clock for on-chip clock generation is introduced. The intermediate frequency filter is a digital alternative to today's analog filters. READ MORE

3. Digital signal processing methods and algorithms for audio conferencing systems
Abstract : Today, we are interconnected almost all over the planet. Large multinational companies operate worldwide, but also an increasing number of small and medium sized companies do business overseas. As people travel to meet and do businesses, the already exposed earth is subject to even more strain. READ MORE

4. ASIC Implementation of a Delayless Acoustic Echo Canceller: Architecture and Arithmetic
Abstract : Application specific digital signal processors are superior compared to standard digital signal processors in a number of application fields, mainly due to high throughput and low power consumption traded for flexibility. This thesis deals with two areas related to hardware implementation of custom digital signal processors: design methodology and efficient implementation of arithmetic circuits. READ MORE

5. Integrated Optimal Code Generation for Digital Signal Processors
Abstract : In this thesis we address the problem of optimal code generation for irregular architectures such as Digital Signal Processors (DSPs).Code generation consists mainly of three interrelated optimization tasks: instruction selection (with resource allocation), instruction scheduling and register allocation.
