TITLE:		Compromised Computihg:  The Practical Approach to Energy
 		Efficient System Design


SPEAKER:	ANDREAS OLOFSSON  (Adapteva, Inc.)


ABSTRACT:

The last 40 years has seen incredible improvements in computing 
performance, power efficiency, density and cost.  Unfortunately, it looks 
like the free ride is over and we are now faced with some serious issues 
to keep this trend going.  Single-threaded performance stopped scaling 
years ago and chip designers are now having serious power issues as 
process technology scales to 28nm and beyond.  As an industry we are now 
faced with a tough choice. Do we continue with the traditional programming 
model for high performance applications and accept the fact that the 
processing budget will be strictly limited by our battery/electricity 
budget or do we adopt a radical new programming model that would allow us 
to significantly reduce the hardware overhead associated with traditional 
Von Neumann architectures.  We present a "compromised computing" approach 
to the problem, which combines a new C-programmable floating point math 
accelerator with traditional silicon architectures to enable real 
applications with an immediate order of magnitude better energy 
efficiency.
