TUM builds its own AI Chip using 7 nm Technology

The Covid pandemic, the war in Ukraine and geopolitical changes have made supply chains uncertain. "That's why it will be important in future to take all steps in Germany and Europe, from the training of AI chip specialists to the technological development and production of AI chips," says Amrouch. Just three months ago, he opened the AI chip research and training center Macht-AI at TUM - funded by the Bavarian Ministries of Science and Economic Affairs. In future, he envisages that students in Germany will learn AI chip design and develop AI chips and algorithms themselves in companies. It will also be possible to produce them in Germany.

AI chip processes data locally

Unlike manufacturers of cloud-based AI chips such as Nvidia, the Munich professor is focusing on a technology that processes data directly on the device and does not send it to the cloud. "This is a fundamental solution for protecting the privacy of our citizens," says Amrouch. The AI chips, which are based on the RISC-V open source standard, can be customized for a specific task, for example to record and evaluate heartbeat or brain signals in a health application or to use a language model. This specialization is more efficient than a one-size-fits-all AI chip. His AI chips will also be used for control electronics in quantum computing in a few years' time.

Data remains private and secure

By processing the data locally, the technology is cyber-secure and therefore also protected against misuse by third parties. "Whoever designs and builds the chip knows what is inside and can guarantee what it will do," says Amrouch, who believes it is important that companies can guarantee their customers the privacy of their data.

For economic sectors such as the automotive industry, trust is an important 'currency' that is currently not in European hands when it comes to powerful chips. And the defense industry also demands absolute security when it comes to the use of chips for drones, for example. Possible built-in Trojans are an incalculable risk here, especially if chips are developed and manufactured outside Germany and the EU.

Bavaria's Science Minister Markus Blume says: "A real AI coup at TUM! The EU's first AI chip with 7-nanometer technology comes from Bavaria. It combines performance, energy efficiency and security. The fact is: With Power AI, TUM is at the heart of our Bavarian semiconductor ecosystem. In order to be competitive, independent and sovereign, we develop technologies and train talent here."
