Research Interests

Algorithms, architectures, circuits, and VLSI design for high-performance, energy-efficient, and area-efficient computation with strong consideration of the challenges and opportunities of future fabrication technologies.

Research Activities

Dr. Baas' research activities involve the development and implementation of efficient and novel computational hardware with a focus on digital signal processing (DSP) workloads, which are becoming increasingly important in high-growth application areas from portable electronics to data-centers.

Active projects involve both programmable and dedicated-purpose processors. Recent projects include the AsAP (Asynchronous Array of simple Processors) programmable array processor chip, applications, compiler and mapping tools; Low Density Parity Check (LDPC) decoders; Fast Fourier Transform (FFT) processors; Viterbi decoders; and H.264 video encoders and decoders.

The 0.18 m CMOS AsAP chip contains 36 programmable processors, operates at over 610 MHz at 2.0 V, and is believed to be the highest clock rate processor designed in any university. The second generation AsAP2 processing platform contains 167 processors and has been implemented in 65 nm CMOS. It contains numerous architectural and circuit innovations and operates at over 1 GHz.


Bevan Baas was a National Science Foundation Fellow from 1990-93 and a NASA Graduate Student Researcher Fellow from 1993-96. He received the National Science Foundation CAREER award in 2006, and the Most Promising Engineer/Scientist Award by AISES in 2006.
