Description: 

Abstract: With diminishing returns from technology-scaling,
accelerators have been proposed as an attractive path forward for
improving processor performance. One aspect of accelerators is to
focus on their power reduction (compared to general-purpose cores) and
another is their performance. In this talk we will describe an
ordinary architecture organization that allows the design of
accelerators that can be programmed in software using ordinary
mechanisms like threads, transactions etc. I will then show how one
use this architecture to achieve 10X to 100X speedups over
conventional processor and match the speedups of novel specialized
domain-specific accelerators. Finally, I will show why the
power-consumption of this accelerator is inconsequential and why
future accelerators can be designed ignoring power consumption!
