Company overview

Kalray was founded in 2008 as a spin-off from the CEA (the French Department of Energy lab), one the largest research labs in Europe, capitalizing on over 50 years of research and development on new architecture processors.

Kalray is a fabless semiconductor company and a pioneer in developing a new generation of extreme-computing, low-power and low-latency microprocessors. Kalray’s processors are at the heart of the artificial intelligence revolution, designed to fuel the next generation of intelligent embedded systems such as smart storage servers and autonomous vehicles. The intelligent processor market is believed to be worth several billions by 2020.

Today, Kalray employs over 65 employees across its French headquarters (Grenoble & Sophia Antipolis), its North American branch in Los Altos (CA), USA and in Tokyo, Japan. Kalray is backed by prominent financial partners as well as large corporate venture funds, such as European aerospace champion Safran.

Kalray went public in June 2018 raising more than $50 Million – the most significant IPO since the creation of Euronext Growth in Paris.

Product information


The foundations of Kalray’s solutions lie in its manycore architecture, the MPPA® (Massively Parallel Processor Array). This breakthrough technology, protected by over 20 patents, addresses the issues raised by the new generation of intelligent systems:

  • Extreme computing
  • Low-power consumption
  • Real-time processing
  • Full programmability
  • Support of complex systems running multiple critical functions


The Kalray processors are at the core of the new generation of intelligent systems in need of intensive, real-time computing. Kalray is presently focused on two main markets:

  • Embedded intelligent systems, such as autonomous vehicles
  • Data centers: Kalray’s processors enable new-generation intelligent storage systems and networking cards

By 2020, the commercial potential of these markets is estimated at $ 3,25 billion with the emergence of artificial intelligence and rapid memory storage (Sources: Gartner/IDC).

Autonomous vehicles

Present-day cars are brimming with electronics, providing them with a wide variety of assistance functions. However, in order to produce autonomous vehicles, the amount of electronics within cars will skyrocket in so far as more autonomy requires more capabilities and much more computing power: deep learning, computer vision, sensor fusion are all compute-intensive functions, yet they are just a subset of what needs to run in parallel. Car OEMs and Tier 1s require processing solutions which can deliver sufficient computing power while ensuring the highest degree of safety and security.

The MPPA® advantage:

Based on our signature MPPA technology, Kalray’s autonomous vehicle technology has proven to be the perfect fit for the needs of the automotive sector. The MPPA is the ideal optimized processing solution for autonomous vehicles.

Key Benefits:

  • Extreme computing: with 288 cores, the current MPPA processor offers a previously unreached level of heterogeneous compute power. Its ability to execute simultaneously multiple independent applications and multiple threads of the same application provides car makers with a highly efficient processor to integrate all time-critical heavy-computing functions of the Autonomous Driving System on the same die. In addition, the MPPA offers an optimized tool and libraries allowing the best performances of deep-learning or vision-type algorithms. The inherent scalability of the MPPA architecture further allows architects to use one, two or more MPPA processors depending on the level of performance they require.
  • Safety: architectural determinism ensures reliability and security. Compared with other autonomous vehicle processing solutions, Kalray can ensure this high level of safety. The MPPA processor supports ASIL B/C and fulfils the ISO 26262 standard.
  • Power consumption: with a power consumption that can be as low as one tenth of that of existing solutions, architects can develop very dense systems with no, or limited, cooling needs, thus reducing the cost of the solution and of the maintenance dramatically.
  • Programmability: as car electronic infrastructures are moving from a multitude of disseminated small processors (ECU) to a much more centralized platform supporting a wide number of functions, car makers and Tier 1 need an open, easy-to-program platform, that can be easily customized and updated. Thanks to the MPPA programmability, not only can standard C/C++/OpenCL code libraries, standard libraries (OpenCV, OpenVX, …) or run-time environment (AUTOSAR) be used, but also plug-ins to existing code generation tools, allowing the reuse of an easy legacy code.

Data storage

With the adoption of high-speed, low-latency SSDs, new performance bottlenecks are being created at different points along the data path. The emerging NVMe-oF protocol is being deployed to help alleviate these bottlenecks and enable a disaggregated storage model to scale compute and storage resources independently.

The MPPA® advantage:

Kalray has introduced several data storage solutions that respond to the evolving needs of the data center industry.

Key Benefits:

  • KTC products: equipped with Kalray’s MPPA processor, the KTC products (Kalray’s NVMe-oF Target Controllers) have fully integrated CPU + NIC functions which enable high-density/high-performance storage solutions with in-line processing capabilities such as deduplication, encryption, compression, RAID, etc.
  • JBOF: the JBOF (Just A Bunch of Flash drives) reference system further helps customers evaluate the solution.

With Kalray’s MPPA offering more than 100 cores towards end-user processing, Kalray offers customers the chance to make their JBOF smarter while exploiting the performance of SSDs to the fullest!

Data networking

Virtualization has changed the face of many industries, but none so much as networking for telecommunications and data centers. Data centers are quickly adopting two new techniques, Network Function Virtualization (NFV) and Software-Defined Networking (SDN), which offer software and cloud-based solutions in order to avoid costly and frequent hardware updates.

The MPPA® advantage:

Kalray offers several programmable SmartNIC solutions, which allow telecommunications and data centers to completely offload their compute-heavy CPUs. With real-time processing, reliably low-latency and standard C/C++/OpenCL programmability, customer can maintain line-rate performance implementing solutions such as Juniper Contrail and RedHat Openstack.
