Our microprocessor will contribute to Europe’s technological sovereignty.

SiPearl in a nutshell


SiPearl is building the European high-performance low-power microprocessor dedicated to AI inference and supercomputing. This new generation of microprocessors will first target EuroHPC Joint Undertaking ecosystem, which is deploying world-class supercomputing infrastructures in Europe for solving major challenges in medical research, security, energy management and climate with a reduced environmental footprint.

SiPearl, designing the European microprocessor

Created by Philippe Notton in June 2019, SiPearl is the company bringing to life the European Processor Initiative (EPI) project. The aim of EPI is to foster the deployment in Europe of high-performance and low-power microprocessor technologies. Privately held, SiPearl is supported by the European Union. It is established in France, Germany and Spain.

SiPearl is designing and will bring to market the European microprocessor that will help Europe’s supercomputers to achieve exascale(*) power. It works to through close collaboration with its 27 partners from EPI consortium  – scientific community, supercomputing centres and leading names from the IT, electronics and automotive sectors – which are its stakeholders, future clients and end-users.

(*): One billion billion calculations per second.


Operational launch
with European funding of €7.4m

Created in June 2019, SiPearl moves into its operational phase with €7.4m funding from the European Union’s Horizon 2020 research and innovation program under specific grant agreement no.826647.

The company launches the design of its first generation microprocessor, Rhea.

Our ecosystem


1st European deployment
with the opening of SiPearl GmbH

Less than one year after is creation, SiPearl confirms it commitment to scale in Europe by opening its first international subsidiary, SiPearl GmbH, based in Duisburg, Germany

Frank Gorris, previously Digital Design Lead for several 3G to 5G system-on-chip (SoC) solutions with the Intel Group, heads it up.

SiPearl opens site in Barcelona

SiPearl opens its second international subsidiary in the capital of Catalonia. The company thus becomes closer to its partners in Southern Europe, including the Barcelona Supercomputing Center (BSC).

Previously Strategic Project Manager at BSC, Anna Riverola is appointed as the head of SiPearl SL.

Philippe Notton EIC Fund

SiPearl awarded a funding from EIC Accelerator
€15m in equity investments and €2,5m grant

This funding will support the development and scale-up of SiPearl future-generation microprocessor.

The company received €2.5m grant and up to €15m in equity subscribed by EIC Fund.

Initial closing of Series-A with €90m

Investors are:
– Arm,
– Atos Group, through its Eviden business,
– European Innovation Council (EIC) Fund (€15m already announced),
– The French State, via French Tech Souveraineté.
The financing includes up to €25m in convertible debt from the European Investment Bank (EIB).


JUPITER exascale supercomputer,
lead customer for SiPearl

SiPearl wins an emblematic contract to equip the first Exascale supercomputer in Europe. Named JUPITER, this EuroHPC JU supercomputing infrastructure will be operated by Forschungszentrum Jülich.

It will be built by a consortium composed of Eviden (the Atos Group business leading in advanced computing) and ParTec (the German modular supercomputing company). The expected budget is €273m.

Our ecosystem

They support us

Since its operational launch in January 2020, SiPearl has been financially supported by the European Commission under the Horizon 2020 program. In December 2021, SiPearl was awarded the Accelerator program of the European Innovation Council (EIC) for a total of €17.5m: €2.5m grants and €15m equity subscribed by EIC Fund.

Among our technological partnerships

SiPearl has established key partnerships with leading IP providers. Our company is the only European licensee to use ARM Neoverse V1 platform andbenefits from ARM robust software ecosystem. This partnership with the global semiconductor IP provider accelerates the design of a very high-end offering in terms of both computing power and energy efficiency.

SiPearl also selected Siemens Digital Industries Software for its Veloce Strato emulation platform, Ansys for validation of semiconductor power integrity and minimization of power consumption, Synopsys…

Manufacturing will initially be entrusted to the Taiwanese TSMC, first independant semiconductor foundry for an etching 6nm or better.

Our partners
in the HPC ecosystem

Sipearl has established two partnerships with two leader manufacturers: Eviden, the next-gen technology leader in data-driven, trusted and sustainable digital transformation, and HPE, the global leader

To best meet the expectations of its end-users, SiPearl collaborates with AMD for its Instinct™ accelerators, Graphcore for its Intelligence Processor Unit (IPU), Intel for Ponte Vecchio GPU family and NVIDIA for its accelerated computing and networking portfolio.

Organizations we belong to

SiPearl is a member of many technology consortiums, such as ANRT, which gathers public and private actors in research and development, France Digitale, the leading startup and investor association, France Deeptech, the community which gathers together actors in deeptech and Teratec, the European competence center for high-performance digital simulation. SiPearl is also a member of Systematic, the European Deeptech cluster, JEDI Foundation, European funding agency, PlayFrance.digital, collective which brings together more than 300 French digital players, GIM, professional industrial organization of Ile-de-France and of Industrial Alliance on Processors and Semiconductor Technologie. The company is also a member of the ETP4HPC think tank dedicated to research and innovation in European high performance computing to further Europe’s competitiveness. It’s also a member of Minalogic, the digital technology cluster for France’s Auvergne-Rhône-Alpes region, GSA, organization dedicated to semiconductors, and GEBS, network which highlights company directors.

Our commitment to sustainable growth


By giving Europe the means for early detection of diseases, to fight climate change more effectively, to produce better quality goods and services, the high-performance, low-power microprocessors developed by SiPearl will bring important environmental, social and societal benefits.

SiPearl’s progressive approach to sustainable growth includes promoting diversity in recruitment and taking steps to minimize the impact of its activities on the environment (hosting green servers at Ikoula, opening offices close to labor pools, limiting paper consumption).

In December 2023, SiPearl launched its first carbon footprint as part of Diagnostic Décarbon’Action.
