High-speed interconnect for low-latency multi-node systems

Built for systems where conventional networking adds too much latency or overhead, the technology supports PCIe-based interconnect, reflective memory, resource expansion, and shared multi-node architectures. Primionics develops relevant Indian opportunities where low-latency communication or PCIe resource sharing can materially improve system behaviour.

PCIe hardware and software for multi-computing systems

Focused on PCIe hardware and software for multi-node computing rather than generic IT networking, the portfolio is relevant where low-latency data movement, shared memory behaviour, direct device access, or expansion beyond the local chassis matter.

The range includes NTB adapters, switch systems, PCIe software, reflective memory, PXIe and VPX products, and PCIe expansion platforms for embedded, scientific, industrial, and OEM applications.

  • Relevant where Ethernet-class latency is too high
  • Useful for shared-memory and low-overhead node-to-node communication
  • Strong fit for simulation, expansion, embedded systems, and fast data movement
  • Best introduced through use-case discussions and workflow fit

Core building blocks across the Dolphin platform

NTB Host Adapters

PCIe host and target adapter families for non-transparent bridging, enabling low-latency node-to-node communication, clustering, and high-speed interconnect across multiple PCIe generations.

PCIe Switches & Fabric Systems

External and embedded PCIe switch platforms that build scalable multi-node topologies for resource sharing, distributed computing, and high-throughput PCIe fabrics.

Reflective Memory / Multicast

Hardware-based reflective memory and multicast capabilities for deterministic data replication, shared-memory communication, and real-time system synchronisation over PCIe.

eXpressWare Software

Dolphin’s PCIe software suite extends the hardware with shared-memory APIs, TCP/IP over PCIe, low-overhead messaging, device access, and application development tools.

PCIe Expansion & Device Sharing

Solutions for extending GPUs, FPGAs, NVMe, and other PCIe devices beyond the local host, with support for remote I/O access, PCIe expansion, and peer-to-peer data paths.

PXIe, VPX, CompactPCI Serial & Automotive

Dolphin solutions also extend into PXIe, VPX, CompactPCI Serial, embedded multi-computing, and automotive PCIe software environments for specialised high-performance systems.
