      High-Speed Camera Interfaces with Fraunhofer HHI TCP/IP

      ,

      Excelitas PCO GmbH has licensed MLE NPAP, the TCP/UDP/IP Full Accelerator originally invented by Fraunhofer Heinrich Hertz Institute (HHI).

      Martin Schwarzbauer, Product Development Manager Camera Systems at PCO, says: “We rely on the TCP protocol because we need reliable data without a backup layer for lost data at the application level. TCP takes place at the center protocol layer of the OSI model and is implemented as an IP core in FPGA logic. This results in significantly shorter latency, avoiding costly external DRAM buffers. Plus, due to the flow-control mechanism of TCP, the transmission bandwidth can be much higher between the between the camera and subsequent processing in a PC.”

      Alexander Grünig, CTO of PCO, adds: “The IP core from Missing Link Electronics fits perfectly our streaming concept, because it operates in programmable logic without the need for a CPU core. During our benchmarking and evaluation phase we clearly saw the advantages of this technology.”

      PCO, an Excelitas Technologies® Corp. brand, is a leading specialist and Pioneer in Cameras and Optoelectronics with more than 30 years of expert knowledge and experience of developing and manufacturing high-end imaging systems. The company’s cutting edge sCMOS and high-speed cameras are used in scientific and industrial research, automotive testing, quality control, metrology and a large variety of other applications all over the world.

      The PCO® advanced imaging concept was conceived in the early 1980s by imaging pioneer, Dr. Emil Ott, who was conducting research at the Technical University of Munich for the Chair of Technical Electrophysics. His work there led to the establishment of PCO AG in 1987 with the introduction of the first image-intensified camera followed by the development of its proprietary Advanced Core technologies which greatly surpassed the imaging performance standards of the day.

      Today, PCO continues to innovate, offering a wide range of high-performance camera technologies covering scientific, high-speed, intensified and FLIM imaging applications across the scientific research, industrial and automotive sectors.

      Acquired by Excelitas Technologies in 2021, PCO represents a world renowned brand of high-performance scientific CMOS, sCMOS, CCD and high-speed cameras that complement Excelitas’ expansive range of illumination, optical and sensor technologies and extend the bounds of our end-to-end photonic solutions capabilities.

      MLE Joins Github Project CORUNDUM for In-Network Compute

      CORUNDUM.io is an open-source project hosted at Github for building high-performance FPGA-based Network-Interface Cards (NIC) or in-network compute platforms / SmartNICs. “Our motivation for joining is to build better and more cost-effective SmartNIC solutions by complementing FPGA Full Acceleration using NPAP, the TCP/IP Stack that I started at Fraunhofer HHI, with a performance oriented hardware/software infrastructure”, says Ulrich Langenbach, Director Engineering at Missing Link Electronics. Engineering work plans include enhancing support for Xilinx Zynq UltraScale+ MPSoC and for porting CORUNDUM to some of MLE’s partners’ FPGA boards.

      Wie Auto-TSN PCIe mit Ethernet zur Datenübertragung kombiniert

      Unser Beitrag für die PCI-SIG Virtual Developers Conference 2021 wurde als Artikel in der Zeitschrift Automobil Elektronik abgedruckt.

      Auto/TSN ist der Arbeitstitel für eine Technologie, mit der automotive Daten samt PCIe via Time-Sensitive Networking (TSN) übertragen werden können. PCI Express (PCIe) kennen viele Entwickler und Anwender aus dem PC, beispielsweise als Anschluss für die Grafikkarte oder für schnelle NVMe-Massenspeicher. Ebenso bekannt ist Ethernet, mit dem sich zu Hause oder im Büro Rechner und Drucker usw. vernetzen lässt. IEEE Ethernet in Form von 100/1000Base-T1 fährt heute bereits auf der Straße. Aber warum wird PCIe immer mehr ein Thema im Automobil-Bordnetz? Was bedeutet PCIe im Fahrzeug und wie kann PCIe eingesetzt werden, sodass das Gesamtsystem zuverlässig ist?

      Zone-Based Automotive Backbones Tunneling PCIe

      Missing Link Electronics (MLE) announced today that they are partnering with Fraunhofer Heinrich-Hertz-Institute (HHI) and Fraunhofer Institute for Photonic Microsystems (IPMS) on ultra-reliable, deterministic low-latency transports for automotive networks tunneling PCI Express® (PCIe®) architecture.

      The need for more safe and eco-friendly vehicles drives automotive connectivity towards so-called Zone-Based Architectures. Inside those so-called Zone Gateways PCIe technology provides the connectivity between multiple System-on-Chip (SoC), CPUs, GPUs, and FPGAs for scalable performance. Within the automotive network, multiple Zone Gateways connect with each other via the emerging IEEE standards “Time Sensitive Networking” (TSN).

      Today, Fraunhofer and MLE can provide a working proof-of-concept in form of a digital circuit & system stack which encapsulates and decapsulates PCIe packets (and other protocols) over real-time automotive TSN Ethernet and which scales up to 100 Gbps.

      “When we started working on network protocol acceleration in 2010 we looked at future connectivity needs for systems-of-systems such as ships and cars”, states Ulrich Langenbach, formerly with Fraunhofer HHI and now Director Engineering at MLE. “Therefore, our approach does address key topology requirements for modern vehicles which is reliable and cost-efficient PCIe long-range, support for NVMe SSD storage, as well as CPU-to-CPU communication via PCIe Non-Transparent Bridges (NTB)”.

      “Our approach of closely adhering to the OSI Layers makes our TSN Switched-Endpoint very interoperable with different Ethernet PHY solutions”, says Marcus Pietzsch, Group Leader IP Cores and ASIC Design at IPMS and emphasizes: “This is vital as the standards and commercial offerings for TSN and for automotive Ethernet are still very fluid!”

      “PCI-SIG’s mission is to bring together developers seeking innovation and product compliance around current and future PCIe specifications,” said PCI-SIG President Al Yanes. “The purpose of PCI-SIG’s Automotive Work Group is to facilitate the discussion of PCIe technology in the automotive ecosystem with member companies like MLE.”
