Artificial intelligence in embedded systems

Artificial intelligence has found its way into many areas to make systems more precise and reliable than previous manually optimized algorithms. One common method is machine learning, which learns to solve predefined tasks on its own based on a large database. But for artificial intelligence to enrich the end application, it must be embedded. A particular challenge here is to compress the networks so that they can be completely computed in the end devices.

Benchmarking for AI Accelerators

When using artificial intelligence in practice, different framework conditions have to be considered that influence the design of an AI system and accelerator. Often, a trade-off is realized between the accuracy of the AI model, hardware resources used, and application requirements. At ITIV, metrics from the different domains are measured to analyze this trade-off and benchmarks are developed to evaluate the overall design. These benchmarks can in turn be used in automated design space exploration to find a suitable hardware/software co-design more quickly.

Assistive Robotics

Many people strive for a long, self-determined life within their own four walls. However, the care crisis means that human care in the home is becoming increasingly rare. As an alternative, KIT is researching assistive robots that help elderly people to cope with everyday life at home. Important aspects for increasing their acceptance are short response times and personalization of the services. For this purpose, ITIV is researching suitable hardware accelerators with low latencies and a high degree of privacy.
