My research focused on compilation for multimedia extensions. For my
doctoral work, I developed selective
vectorization, a technique that balances computation across a
processor's scalar and vector resources. The approach leads to
software pipelines with shorter schedules, and therefore, higher
performance. Selective vectorization is applicable to any design that
supports ILP and short-vector parallelism.

SUIF to Trimaran Converter
For my doctoral work I wrote a set of SUIF passes that convert SUIF IR
to IMPACT Lcode, an IR used in the Trimaran compilation and simulation
infrastructure. These passes, along with an updated version of SUIF,
are now part of the Trimaran 4.0 release. You can download them from
the Trimaran download
