Hi! I am Prasanna Rengasamy.
I am a 4th year PhD candidate at the Computer Systems Lab at Penn State.
My current research involves system level optimizations for improving the performance, power and energy efficiency of handheld app executions. We recently characterized easily acceleratable common instruction sequences for 10 widely popular and diverse handheld apps. Read more...
I am advised by Prof Anand Sivasubramaniam. I also work with Prof Mahmut Kandemir and Prof Chita Das.
