MPPA® TECHNOLOGY

A MASSIVELY PARALLEL PROCESSOR ARRAY ARCHITECTURE

Kalray MPPA® DPU Manycore

A Massively Parallel Processor Array Architecture

The world is facing an explosion of data which current technologies were not initially designed for and cannot always handle efficiently. Industry needs a new type of processor. Enter the era of Intelligent Processors.

The overall architecture of the Kalray 3rd generation of MPPA® DPU processor aka Coolidge™ is based on a “Massively Parallel Processor Array” architecture, which is characterized by the association of computing clusters connected to each other, to the external memory and to the I/O interfaces via two independent interconnects.

The MPPA®’s interconnects are suited to different types of data transfers. The first interconnect is an AXI Fabric bus grid, for use read/write access from cores to memories and peripherals connected by PCIe. The second interconnect by an RDMA NoC (Network-on-Chip), that supports data transfers to or from the Ethernet network interfaces and connect all clusters together.

The robust partitioning necessary for safe operation of the processor is carried out at the granularity of the computing cluster and is based on the configuration of memory management units (MMUs), memory protection units (MPUs), and on the deactivation or not of network on chip links.
