Energy-efficient HPC microprocessor
for exascale supercomputers

Our vision

Philippe Notton, CEO et fondateur de SiPearl, le concepteur du microprocesseur haute performance et basse consommation

Because meeting strategic challenges for Europe in medical research, climate change mitigation or energy management requires processing huge volumes of sensitive data in a fraction of a second, SiPearl is developing the high-performance, low-power and backdoor-free security microprocessor that will be at the heart of European supercomputers.

We are thus contributing to Europe’s technological sovereignty.

Philippe Notton
CEO and Founder


The world’s first energy-efficient HPC-dedicated microprocessor designed to work with any third-party accelerator: GPU, artificial intelligence, quantum.
