If Europe wants to stay apace in artificial intelligence, quantum computing, medical research, climate change mitigation and energy management it will need its own microprocessors to process huge volumes of sensitive data in a fraction of a second. That is where SiPearl, a French fabless chip startup, comes in. It is designing a low-power high performance computing (HPC) microprocessor with backdoor-free security to first power European supercomputers and later data centers as well as helping drive European-made autonomous vehicles, contributing to the technological sovereignty of the Continent.
