Kalray chips are code-named after Mountains. However each chip is called a "MPPA" for "
massively parallel processor array":
MPPA-256 Andey Produced in 2013 in CMOS 28HP technology from TSMC, this SoC (or
System-on-Chip) runs at 400 MHz and contains 256
VLIW 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 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) standard interface (for connecting hosts to PCIe bus-attached SSDs), and also the NVMe over Fabrics standard using
RDMA (for connections between servers, storage controllers, and NVMe enclosures).
MPPA3-80 Coolidge The third-generation MPPA processor Coolidge has been released. 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.
MPPA3-80 Coolidge2 The Coolidge2 DPU Processor was released in 2023 and is aimed at
LLMs, with an additional focus on efficient usage of NVME storage. == Listing on Euronext ==
