**Call for Papers **
***1st Workshop on Approximate Computing*
*In conjunction with HiPEAC 2015*
*January 19, 2015, Amsterdam

Research in the last few years has focused on approximate computing as a 
means to overcome the energy scaling barrier of computer systems. Energy 
savings can be achieved by utilizing the inherent error resilience of 
algorithms in many application domains such as signal processing, 
multimedia, data analytics and computational engineering, among others. 
Indeed, fully accurate arithmetic in specific phases of those 
applications may have only a marginal effect on output quality, 
especially if combined with error correction frameworks such as 
iterative refinement. For example, accurate execution may be traded off 
with lower energy consumption by providing the ability to scale supply 
voltage below nominal values and accommodate errors at the software 
layers, or use a simpler approximate solution such as lower precision 

Designing such systems in a general-purpose computing environment 
requires a holistic view of all layers from algorithms, programming 
models, system software, and hardware down to the transistor level. This 
full-day workshop, which is organized in conjunction with HiPEAC 2015 
<http://www.hipeac.net/2015/amsterdam>, is an inter-disciplinary effort 
to bring together researchers from the areas of mathematics, computer 
science, computer and electrical engineering to discuss challenges, 
risks and opportunities of approximate computing in all design layers.

Papers will be published online in this website, but not in proceedings. 
Submitting to WAPCO will not preclude future publication opportunities.
