      Artificial Intelligence algorithms and machine vision with high-resolutions and fast frame-rates continue to drive towards higher bandwidth demands in real-time industrial networks.

      Under the working title “Robo/TSN”, MLE and partners have developed open standards technology for multi-Gigabit TSN (Time Sensitive Networking). Solutions include endpoints, switched endpoints and SmartNICs to enhance existing infrastructure to 100 Gbps. Use cases are:

        • Connect high speed sensors in the field with AI engines in edge cloud data centers. 
        • Tunnel multiple protocols such as PCIe, MIPI CSI-2, GMSL, field buses like Ethercat or Profinet via virtual connections over high-speed TSN.
        • Transparent connection of sensors and actuators from automation cells to AI engines and/or virtualized/software PLCs in edge cloud data centers via high-speed TSN.
        • Tunnel field bus protocols from the automation cell through the TSN backbone to your edge cloud/ data center and integrate e.g. an AI engine as a field Bus slave providing control data to the Field Devices.
        • Offload computing and controlling/ PLC tasks to edge cloud/ data center infrastructure with all advantages like virtualization, containerization, redundancy, backup organization etc. and without any compromises concerning real-time and high-speed requirements.
        • Use all advantages imaginable by having a high speed time sensitive network through the whole production plant.

      Robo/TSN for Industrial Multi-Gigabit Ethernet

      AI and videos need high data rates and are breaking industrial networking. In industrial environments and control technology, real time requirements are common practice. Since camera technology, image recognition or AI become more and more usual, hard real time requirements combine with extremely high data rates. Sensors provide up to 25 Gbps data which has to be transferred, processed and evaluated real time with reliable low latency.

      MLE’s backbone-oriented approach allows it to tunnel modern multi-Gig sensor data (GigEVision, PCIe, MIPI CSI-2, GMSL, …) as well as industrial protocols like Ethercat or Profinet. Robo/TSN builds on patented and patent pending technology from MLE (US Patent Nos. 9,209,828 10,708,199 10,848,442 11,356,388 11,695,708, other Patents Pending).

        Data Diodes - Unidirectional Security Gateway

        A data diode or unidirectional network bridge / unidirectional security gateway is a piece of hardware used to connect two separated networks with the purpose to allow data to travel only in one direction, specifically, from one network into another. Applications are found in high security environments where they connect two or more networks of differing security classifications while making it physically impossible to transfer data in the direction from the lower to the higher security classification.

        Data Diodes Application - Example System Protection

        For this, MLE has partnered with Fraunhofer HHI to provide the industry-proven TCP/UDP/IP Network Protocol Acceleration Platform (NPAP) in form of NPAC, a PCIe Network Protocol Accelerator Card with quad-port 10G Ethernet.

        In-Vehicle Network - Auto/TSN

        Auto/TSN stands for automotive data over Time-Sensitive Networks which is an in-vehicle network infrastructure based on open standards such as IEEE Ethernet. Auto/TSN is the results of a collaborative effort between MLE and MLE partners, Fraunhofer HHI and Fraunhofer IPMS.

        Fundamentally, Auto/TSN virtualizes the in-vehicle network infrastructure: Key objective is to reduce costs, increase scalability and enable upgradability for next-generation automotive architectures including electric and/or autonomous vehicles.

        in-vehicle network

        By tunneling sensor data along with PCIe and NVMe over Real-Time Multi-Gigabit Automotive Ethernet Auto/TSN simplifies the wire harness and enables more centralized architectures with higher levels of hardware / software integration. By offering PCIe as a common interface (for sensor-to-CPU and CPU-to-CPU connectivity) Auto/TSN different semiconductor SoCs become interchangeable. This significantly reduces semiconductor dependencies and infrastructure costs at the same time.

        Auto/TSN is highly scalable and supports line-rates up to 50 Gbps in FPGA and 100 Gbps in ASIC. Based on IPv4, the space for addressing nodes is 32 bits wide. The small hardware footprint allows zonal gateways with many ports.

        Auto/TSN is “software-defined” and builds from open standards such as IEEE 802.1Q TSN, IEEE 802.3 Ethernet, IETF TCP/IP, MIPI CSI-2, PCIe 4.0 and NVMe 1.4 and open-source Linux which eases hardware / software / system upgradability.

        Features & Benefits of In-Vehicle Network Auto/TSN

        Auto/TSN is a network infrastructure with a system/software focus which reduces the complexity of connecting sensors and centralized computers because it follows de-facto standards of open source network APIs such as RDMA, Linux netdev or SOME/IP.

        Benefits include:

        • Significant cost-down for in-vehicle networking and wire harnesses
        • Digital circuit implementation for zero CPU load
        • Deterministic and very low transport latencies, typ. within 5 micro-seconds
        • Low footprint enables ASIC or FPGA implementation

        The current implementation of TSN supports time-synchronization (IEEE 802.1AS) with 20 nanosecond precision, traffic shaping (IEEE 802.1Qav, 802.1Qbv), frame replication (IEEE 802.1CB) and stream prioritization (IEEE 802.1Qat) for high reliability, low-cost redundancy for functional safety and real-time behavior. Because for PCIe “best effort” is not sufficient, Auto/TSN implements a reliable transport on top of TSN which is compliant to IETF TCP/IP.

        For in-vehicle network security Auto/TSN can be complemented with state-of-the-art IEEE 802.1AE MAC Security Entities (MACsec) and/or IETF RFC 6071 Internet Protocol Security (IPsec) and/or IETF RFC8446 Transport Layer Security (TLS).

        Various Connectivity Schemes are supported:

        • Single CPU (PCIe Root-Port) to multiple devices (PCIe Endpoints)
        • Single CPU to multiple SSDs via NVM Express (NVMe)
        • Multiple CPUIs to multiple NVMe SSDs (via NVMe proxy)
        • Multiple CPUs to multiple CPUs via Inter-System Bridge (a.k.a. PCIe NTB)
        • Asymmetric sensor connectivity, e.g. MIPI CSI-2 to PCIe
        • IEEE 1722 style video transport
        in-vehicle network - Auto/TSN over 10G/25G/50G Ethernet

        Data-in-motion processing runs on dedicated on-chip full accelerators and frees up the CPUs from protocol handling. Our patented and patent-pending Heterogeneous Packet-Based Transport mechanism packetizes and de-packetizes PCIe, MIPI CSI-2 and other packet-based protocols and features low protocol overhead for high bandwidth and low and deterministic micro-second transport latency.

        PCIe Over Auto/TSN

        Auto/TSN implements a PCIe switch compliant with PCI-SIG Base Specification 3.0 (or newer) and NVM Express Specification 1.2 (or newer).

        PCIe Inter-System-Bridge for Auto/TSN

        Integrated PCIe Inter-System Bridges (a.k.a Non Transparent Bridges / NTB) enable CPU-to-CPU connectivity. The PCIe Inter-System Bridges use a least-cost write-only protocol to deliver very high read/write performance. This allows direct connectivity between sensors and multiple CPUs, GPUs, FPGA, SoCs, peripherals and next-generation storage within the entire vehicle.

        MIPI CSI-2 Over Auto/TSN

        Image sensors can connect via standard MIPI D-PHY and MIPI CSI-2, or else. Multicast functionality transports data from each image sensor to one, or more, central compute units under real-time conditions. Hence, Auto/TSN allows symmetric (e.g. PCIe-to-PCIe) and asymmetric (e.g. MIPI CSI-2-to-PCIe) communication schemes.​

        IEEE 1722 Video Transport Over Auto/TSN

        Complementing the MIPI CSI-2 over Auto/TSN transport, MLE has also implemented a solution that follows the Raw Video PDU Format from IEEE 1722.Similarly, this IEEE 1722 Raw PDU Transport supports point-to-point connectivity or multicast where one sensor's image data can be sent to multiple CPUs simultaneously.


        Auto/TSN is available as a licensable integrated subsystem stack comprising digital circuit implementations and device driver software. This business model gives OEMs and Tier1s full control over how to integrate, either as a dedicated semiconductor component, or as modular function blocks inside a custom System-on-Chip with additional customer-specified functionality.

        MLE has been working with key semiconductor partners to deliver FPGA and ASIC based implementations of Auto/TSN ready for design and for production. Our early access program supports OEMs and Tier1s to perform in-house benchmarking and validation of Auto/TSN.

        Current implementations support gateway nodes with PCIe 3.0 and NVMe 1.2 with up to 4 lanes and with 5 or 8 GT/s, MIPI D-PHY 2.0 with up to 4 lanes and 2 Gbps and MIPI CSI-2 2.0 and up to 8 1G/10G Ethernet ports over copper or over fiber. “Lab Cars” based on professional 3rd party ASIC hardware emulators are available upon request.

        Function Accelerators

        Network Function Accelerators, FACs, NICs and SmartNICs

        NICs, SmartNICs, and Function Accelerator Cards with Network Accelerator

        A Network Interface Card (NIC) is a component that connects computers via networks, these days mostly via IEEE Ethernet – but what makes a NIC a SmartNIC? How can FPGA Network Accelerator make it operate more efficiently and enhance its performance to deliver deterministic networking?

        Performance gap between server CPU and the increasing computational demand of faster network port speeds over the past 40 yearsWith the push for Software-Defined Networking, (mostly open source) software running on standard server CPUs became a more flexible and cost-effective alternative to custom networking silicon and appliances. However, in the post Dennard scaling area, server CPU performance improvements cannot keep up with increasing computational demand of faster network port speeds.

        This widening performance gap creates the need for so-called SmartNICs. SmartNIC not only implement Domain-Specific Architecture for network processing but also offload host CPUs from running portions of the network processing stack and, thereby, free up CPU cores to run the “real” application.

        According to Gartner, Function Accelerator Cards (FACs) incorporate functions on the NIC that would have been done on dedicated network appliances. Hence, all FACs are essentially NICs, but not all NICs/SmartNICs are FACs. When deployed properly, FACs can increase bandwidth performance, can reduce transport latencies and can improve compute efficiency, which translates to less energy consumption.

        Deterministic Networking - Functional Accelerator Cards (FACs) - Landscape
        MLE has partnered with FPGA vendors, Fraunhofer Institutes and EMS partners to implement the FPGA Network Accelerator on FPGA-based FACs which deliver cost-efficient solutions for ultra-reliable, low-latency, deterministic networking.

        Features of FPGA Network Accelerator

        Ultra-Reliable, Low-Latency, Deterministic Networking

        With ultra-reliable, low-latency, deterministic networking we have borrowed a concept from 5G wireless communication (5G URLLC) and have applied this to LAN (Local Area Network) and WAN (Wide Area Network) wired communication:

        • Ultra-Reliable means no packets get lost in transport
        • Low-Latency means that packets get processed by a FAC at a fraction of CPU processing times
        • Deterministic means that there is an upper bound for transport and for processing latency

        We do this by combining the TCP protocol, fully accelerated (in FPGA or ASIC using NPAP), with TSN (Time Sensitive Networking) optimized for stream processing at data rates of 10/25/50/100 Gbps. These so-called TCP-TSN-Cores, the FPGA network accelerator, not only give us precise time synchronization but also traffic shaping, traffic scheduling and stream reservation with priorities.

        We believe that FPGAs are very well positioned as programmable compute engines for network processing because FPGAs can implement “stream processing” more efficiently than CPUs or GPUs can do. In particular, when the networking data stays local to the FPGA fabric Data-in-Motion processing can be done within 100s of clock cycles (which is 100s of nano-seconds) and can be sent back a few 100 clock cycles later, an aspect with is referred to as Full-Accelerated In-Network Compute.

        While FPGA technology has been on the forefront of Moore’s Law and modern devices such as AMD/Xilinx Versal Prime or Intel Agilex or Achronix Speedster7t can hold millions of gates, FPGA processing resources must be used wisely, when Bill-of-Materials costs are important. Therefore, at MLE we have put together a unique combination of FPGA and open-source software to achieve best-in-class performance while addressing cost metrics more in-line with CPU-based SmartNICs.

        Meanwhile highly optimized for networking​


        An open source multi-layer network switch​


        A vendor-neutral open-source high-performance FPGA-based NIC


        Software for Opensource Networking in the Cloud​​

        The GitHub project focusing on AMD/Xilinx Alveo cards​

        Xilinx Vitis HLS LLVM

        The High-Level Synthesis Frontend for Xilinx FPGAs

        High-Level Synthesis plays a vital role in our implementation as it allows MLE and MLE customers to turn algorithms implemented in C/C++/SystemC into efficient FPGA logic which is portable between different FPGA vendors.

        To build a high-performance FAC platform, portions of the above have been integrated together with proven 3rd party networking technologies:

        Corundum In-Network Compute + TCP Full Accelerator

        Corundum is an open-source FPGA-based NIC which features a high-performance datapath between multiple 10/25/50/100 Gigabit Ethernet ports and the PCIe link to the host CPU. Corundum has several unique architectural features: For example, transmit, receive, completion, and event queue states are stored efficiently in block RAM or ultra RAM, enabling support for thousands of individually-controllable queues.

        Corundum In-Network Compute with FPGA Network Accelerator (TCP Full Accelerator)MLE is a contributor to the Corundum project. Please visit our Developer Zone for services and downloads for Corundum full system stacks pre-built for various in-house and off-the-shelf FPGA boards.

        MLE combines the Corundum NIC with NPAP, the TCP/UDP/IP Full Accelerator from Fraunhofer HHI, via a so-called TCP Bypass which minimizes processing latency of network packets: Each packet gets processed in parallel by the Corundum NIC and by NPAP. The moment it can be determined that the packet shall be handled by NPAP (based on IP address and port number) this packet gets invalidated inside the Corundum NIC. If a packet shall not be processed by NPAP, it get’s dropped in NPAP and will solely be processed by the Corundum NIC.

        Fundamentally, this implements network protocol processing in multiple stages: Network data which is latency sensitive does get processed using full acceleration, while all other network traffic is handled either by a companion CPU and/or by the host CPU.

        Applications of FPGA Network Accelerator

        MLE’s Network Accelerators are of particular value where network bandwidth and latency constraints are key:

        • Wired and Wireless Networking
        • Acceleration of Software-Defined Wide Area Networks (SD-WAN)
          • Video Conferencing
          • Online Gaming
          • Industrial Internet-of-Things (IIoT)
        • Handling of Application Oriented Network Services
        • Mobile 5G User-Plane Function Acceleration
        • Mobile 5G URLLC Core Network Processing with TSN
        • Offloading OpenvSwitch (OvS), vRouter, etc

        Compared with plain CPU software processing MLE’s Ultra-Reliable Low-Latency Deterministic Networking increases network bandwidth and throughput close to Ethernet line rates, in particular for smaller packets, which reduces the need for over-provisioning within the backbone. And, processing latencies can be shortened significantly which is important, for example, when delivering a lively audio/video conferencing experience over WAN.


        MLE’s FPGA Network Accelerator is available as a licensable full system stack and delivered as an integrated hardware/firmware/software solution. In close collaboration with partners in the FPGA ecosystem, MLE has ported and tested variations of the stack on a growing list of FPGA cards.
