Brief Bio

 I currently work at the Nokia Research Center in California. Before that I completed the PhD and MASc degree programs from the University of Toronto's ECE department in 2009 and 2005 respectively. I received my BASc from the University of Toronto's Engineering Science program in the Computer Option in 2003. In 2006, I worked at Intel Microarchitecture Research Labs.

Research

 My research interests are in systems architecture/design, and reconfigurable devices. My graduate work has been in FPGA-based soft processors and their customization. We've developed an infrastructure for rapidly generating efficient RTL descriptions of a processor from an input description. We've dubbed the system SPREE (Soft Processor Rapid Exploration Environment) and more can be found about it by going to The SPREE Home Page. We've migrated SPREE to real hardware connected to DDR SDRAM and found that our embedded benchmarks are generally compute bound. Recently we've investigated adding vector extensions to soft processors as a means of increasing their compute power in a scalable and user-selectable way. For more information on this project please visit the The VESPA Home Page.
