Bakos

Dr. Bakos's research interests involve computer architecture at the circuit level, micro-architectural level, and system level. This includes VLSI design, design automation, system-level interconnects, reconfigurable computing and high-performance computing.

Dr. Bakos's current research emphasis is heterogeneous computing, which is a computing model where one or more general-purpose processors are accelerated by one or more special-purpose co-processors. When an application is run on a heterogeneous platform, the co-processor is programmed to perform a parallelized implementation of the application's kernels, the fundamental computations that consume nearly all the execution time. Since the co-processor can potentially execute the kernels hundreds or thousands of times faster than a general-purpose processor, the entire application can be significantly sped up. Dr. Bakos's research group has adapted several scientific applications for heterogeneous computing, designed customized arithmetic units for co-processors, developed tools that assist developers in adapting legacy code to heterogeneous platforms, and developed simulation techniques for performance tuning co-processor code.
