Dr. Bhattacharyya is exploring how emerging hardware platforms allow for more advanced software for image-processing applications. His research interests include architectures and design tools for signal processing systems, biomedical circuits and systems, embedded software, and hardware/software co-design.
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 arising from audio signals, images, video streams and digital communication waveforms. The group works 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 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:
• Memory and buffer management for DSP hardware and software.
• Applications and tools for configurable computing.
• Mapping algorithms onto embedded multiprocessor systems.
• Mapping algorithms onto multiprocessor DSP systems.
• New computational models for more efficient programming of DSP systems.
• Novel architectures for improving performance and predictability of DSP
applications.
• Low power implementation of DSP applications.
• Standardizing dataflow graph semantics in a new dataflow language, called DIF
(dataflow interchange format).
• Architecture and optimizations for low power sensor networks.
