The Maryland DSPCAD Research Group

Overview People Projects Publications Theses Group Events

 

   The Maryland DSPCAD Research Group focuses on computer-aided design and implementation of digital signal processing (DSP) systems. DSP refers to the digital analysis and manipulation of data streams, such as those associated with audio signals, control system components, digital communications waveforms, images, and video streams. We work on many aspects of architectures and software tools for DSP system design, including specialized programming languages; synthesis and optimization of hardware and software; hardware/software co-design; and DSP implementations on field-programmable gate arrays (FPGAs) and custom-designed integrated circuits. The long-term goal of this research is to improve the productivity of designing DSP systems, as well as the reliability, predictability, and efficiency of DSP system implementations. Active research projects in the group, and areas in which we have made significant accomplishments include the following topics:

Ø      Memory and buffer management for DSP hardware and software.

Ø      Applications and tools for configurable computing.

Ø      Mapping algorithms onto multiprocessor DSP systems.

Ø     New computational models for more efficient programming of DSP systems.

Ø      Novel architectures for improving performance and predictability of DSP applications.

Ø      Low power implementation of embedded applications.

Ø      Integrating dataflow graph semantics and analysis techniques in a new dataflow language, called DIF (dataflow interchange format).

Ø      Architecture and optimizations for low power sensor networks.
