MPPA®: The Supercomputing on a chip™ solution

MPPA® is a family of programmable manycore processors ideally suited for real-time compute-intensive, low power applications. It relies on Kalray’s proprietary massively parallel processor array (MPPA®), a revolutionary core technology made up of leading-edge components, resulting from many years of research.


The foundation of Kalray’s supercomputing on a chip™ solutions lie in its breakthrough, patented MPPA® manycore processor technology. This revolutionary architecture allows 288 standard C/C++ processors to run in parallel at high performence, low power and very low latency. MPPA® is the only manycore processor in the world to bring as many as 288 computing cores on the same processor. This is a huge advantage for critical applications like networking and storage in data centers, or self-driving cars where you need to run many independant processes at the same time.

MPPA® architecture provides an unparalleled combination of technology benefits:

  • Industry-leading ratio of computing power/energy consumption
  • Time predictability and low latency (less than 1micro-second input to output)
  • Unique processing scalability
  • System density
  • Ability to run a wide set of heterogeneous applications on one chip
  • High programmability (standard C/C++, OpenCL)

MPPA2®-256 (Bostan)

The MPPA2® high-speed I/O processor (Bostan) is the second generation of Kalray’s manycore processor family. Bostan brings an ASIC-level of performance (high computing, low power consumption and real-time processing) with full programmability. Bostan runs 288 C/C++ programmable cores, optimized for networking and storage applications, and includes high speed interfaces like 80GE and PCIe x16 lane Gen3 directly connected to the large matrix of 288 cores and 128 crypto co-processors.

The Bostan core is a 64-bit Very Long Instruction Word (VLIW).

MPPA®-256 (Andey)

The MPPA®-256 is the first generation of Kalray manycore processor family and is composed by an array of 16 clusters and 4 I/O subsystems, themselves connected by two NoCs.

The MPPA®-256 core is a 32-bit VLIW.



AccessCore™ SDK: A complete, standard-based Software environment

Delivering high performance applications requires the software to closely restitute the full capacity the MPPA® cores.
Kalray’s SDK provides a standard C/C++/Fortran based environment including all the tools to quickly develop, debug, and optimize high-performance applications for the MPPA® processor.


  • Rapid Prototyping: thanks to C/C++ based programming models, IEEE floating point compatibility and fast compilation, developers can design and evaluate their application more quickly than with FPGA-based solutions, enabling a faster time to market.
  • Reuse Legacy Code: Kalray’s SDK, an Eclipse-based programming flows, and ANSI-C/C++ supports enable an easy migration of your legacy single-threaded code to a parallel program.
  • Advanced simulation and profiling: AccessCore™ offers a set of simulation & profiling tools allowing the developers to fine-tune their application.
