**Kalray** is a French [fabless](/source/Fabless_manufacturing) [semiconductor](/source/Semiconductor) company headquartered in [Montbonnot](/source/Montbonnot-Saint-Martin), [France](/source/France).

## Corporate history

Kalray was founded in 2008 as a spin-off of [CEA](/source/French_Alternative_Energies_and_Atomic_Energy_Commission) French lab, with investors such as [Renault–Nissan–Mitsubishi Alliance](/source/Renault%E2%80%93Nissan%E2%80%93Mitsubishi_Alliance), [Safran](/source/Safran), [NXP Semiconductors](/source/NXP_Semiconductors), [CEA](/source/French_Alternative_Energies_and_Atomic_Energy_Commission) and [Bpifrance](/source/Bpifrance).[2][3]

In April 2020, Kalray announced an $8 million investment from NXP which allows them to be able to develop various solutions for autonomous driving together.[4][5]

In January 2022, Kalray negotiated with arcapix Holdings Ltd. for their acquisition. Arcapix is the parent company of pixitmedia and arcastream.[6][7] At the Flash Memory Summit Awards (FMS) in August 2022, Kalray was awarded the Most Innovative Technology award for their Flashbox.[8][9] In May 2023, the IP-CUBE project that is led by Kalray won the "Technological Maturation and Demonstration of Embedded Artificial Intelligence Solutions" label under the "France Relance 2030 – Future Investments" plan.[10][11]

## Product history

The first Kalray patent was filed in 2010. Today the company holds more than 30 patent families,[12] including 2 families with an exclusive CEA license.

On 22 June 2015, Kalray began the distribution of data center acceleration board families: TurboCard and KONIC,[13] for networking and storage applications, both of which can be programmed with either standard [C](/source/C_(programming_language)) or [C++](/source/C%2B%2B).[14] TurboCard and KONIC both utilize the MPPA2-256 Bostan second generation processor.

In January 2019, Kalray and NXP began a partnership for new platforms for automated driving. The [Massively Parallel Processor Array](/source/Massively_Parallel_Processor_Array) (MPPA) chips from Kalray together with the two NXP chips will be used in the new BlueBox 2.0.[15] Together with [Wistron](/source/Wistron), Kalray launched the FURIO1200 storage system in January 2021.[16][17] The K200-LP [accelerator card](/source/Hardware_acceleration) was launched in June 2021.[18]

Kalray was granted a fund from the French government in May 2023 to develop the Dolomites manycore processor.[19][20]

## Kalray chips

Kalray chips are code-named after Mountains. However each chip is called a "MPPA" for "[massively parallel processor array](/source/Massively_parallel_processor_array)":

### MPPA-256 Andey

Produced in 2013 in CMOS 28HP technology from TSMC, this SoC (or [System-on-Chip](/source/System_on_a_chip)) runs at 400 MHz and contains 256 [VLIW](/source/Very_long_instruction_word) processing cores.

### MPPA2-256 Bostan

Produced in 2015 with the same CMOS 28HP technology from TSMC, this SoC running at 550 MHz was enhanced to increase the floating-point performance of the VLIW cores, to natively support the [Linux](/source/Linux) operating system, and to process high-speed Ethernet (up to 80 Gbit/s). Each VLIW core was extended with a tightly coupled cryptographic coprocessor for security protocol acceleration.

### MPPA2.2-256 Bostan2

Produced in 2017, this processor is based on the previous generation, Bostan, with an improved DDR controller, Ethernet controller and PCIe controller. As a result, this processor fully supports the NVM Express ([NVMe](/source/NVMe)) standard interface (for connecting hosts to PCIe bus-attached SSDs), and also the NVMe over Fabrics standard using [RDMA](/source/Remote_direct_memory_access) (for connections between servers, storage controllers, and NVMe enclosures).

### MPPA3-80 Coolidge

The third-generation MPPA processor Coolidge has been released.[21] Based on TSMC 16 nm FinFET process technology, this processor includes 80 64-bit VLIW processing cores distributed among 5 clusters, 8x 25 Gbit/s Ethernet and 16x PCIe Gen4 interfaces. Each VLIW core is extended with a tightly coupled tensor co-processor for deep learning application acceleration.[22]

### MPPA3-80 Coolidge2

The Coolidge2 DPU Processor was released in 2023 and is aimed at [LLMs](/source/Large_language_model), with an additional focus on efficient usage of NVME storage.[23]

## Listing on Euronext

In 2017, ahead of the launch of Kalray's third-generation microprocessor, Safran[24] and Pengpai joined the company's historical investors (mainly CEA Investissement, ACE, INOCAP).[25] In 2018, Alliance Ventures (strategic venture capital fund operated by [Renault-Nissan-Mitsubishi](/source/Renault%E2%80%93Nissan%E2%80%93Mitsubishi_Alliance)) and Definvest (an investment fund managed by [Bpifrance](/source/Bpifrance) on behalf of the French Ministry of Armed Forces) also acquired stakes in Kalray.[26]

On June 12, 2018, Kalray launched its IPO on the [Euronext Paris](/source/Euronext_Paris) Stock Market[27] and raised €47.7M (after exercise of the over-allocation option), "the most significant IPO since Euronext Growth was created in Paris."[28]
