ARTEFaCT at DATE’17

Special session on Approximate Computing for IoT

The ARTEFaCT partners have organized a hot-topic special session at DATE’17 on Approximate Computing for improving power efficiency of IoT and HPC.

Power efficiency is the primary concern of IoT-related applications, both at the sensor node and on its cloud-computing counterpart. Unfortunately, achieving high efficiency and robustness requires complex and conflicting design constraints. Fortunately, the inherent error resiliency of many IoT applications allows the use of Approximate Computing techniques leading to great benefits on power efficiency while having a minimal impact on the applications. This special session has shown how Approximate Computing techniques applied at hardware and software levels can leverage the power issue both for sensor-node and HPC (High-Performance Computing) ends.
