Improved energy efficiency of artificial intelligence: Fraunhofer participates in Germany’s Sprungin

Improved energy efficiency of artificial intelligence: Fraunhofer participates in Germany’s Sprunginnovationen competition with the ADELIA project

Germany’s Federal Ministry of Education and Research (BMBF) has launched its first-ever competition dedicated to the development of an innovative, energy-efficient AI system. The Fraunhofer Institutes IIS and IPMS have entered their joint ADELIA (Analog Deep Learning Inference Accelerator) project into the BMBF’s Sprunginnovationen competition, where their focus is on the design of an analog inference accelerator ASIC. Fraunhofer IIS leads the project.

Whether for voice, health or parking assistance, artificial intelligence forms the backbone of the smart assistants we use every day. However, such computer systems consume large quantities of energy, which is why new, more efficient energy concepts are becoming essential.

To help address the energy problem, the BMBF is running the AI Sprunginnovationen competition – aimed at driving innovation through creative, disruptive ideas – to support projects of particular interest to technology and society. A total of eleven participants from universities and research institutions are taking part and working on solutions for energy-efficient AI processing. The participants are given access to a database containing real training data and their task is to develop an AI solution that reliably detects signs of medical conditions, such as atrial fibrillation, from this ECG data.

“Our team combines interdisciplinary experience from the fields of low-power integrated circuit (IC) development, medical engineering, machine learning and signal processing, all of which are key to developing an energy-efficient ASIC for AI applications,” explains Dr. Loreto Mateu, ADELIA project manager and group leader at Fraunhofer IIS.

“The ADELIA project aims to come up with an energy-efficient solution for evaluating ECG data to reliably identify ventricular fibrillation,” explains Dr. Thomas Kämpfe, group leader at Fraunhofer IPMS. “The issue with many applications, especially battery-powered mobile devices, is that current AI systems consume way too much power.”

The project is part of a new approach to research funding in Germany, whereby for the first time funding goes to participating teams who then compete to develop a solution to a particular problem. Eleven teams in total are competing in three categories (FPGA, ASIC-130 and ASIC-22FDX) to come up with solutions for different technological applications. The winners of the three categories each have the chance to work with industry and users to put their innovative ideas into practice.

Fraunhofer IIS and Fraunhofer IPMS have teamed up to compete in the category to design a solution for the 22FDX® FD-SOI technology developed by GLOBALFOUNDRIES Dresden Module One LLC & Co KG. Both institutes are focusing their development work on an energy-efficient analog crossbar-based accelerator. Potential applications range from energy-efficient ASICs for human-machine communication to dedicated wearables for the diagnosis of medical conditions.
