Zone-Based Automotive Backbones Tunneling PCIe
Presentation at PCI-SIG Virtual Developers Conference 2021, May 25-26
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.
PCIe-over-TCP-over-TSN-over-10/25GigE
Presentation at 4th Workshop "Programmable Processing for the Autonomous / Connected Vehicle", Sept. 24, 2020 at TH Ulm, Germany
ADAS and Autonomous Driving push the migration towards Zone-based architectures, which again push for more bandwidth and real-time capabilities in the Automotive Network. Based on open IEEE standards and a unique combination of technology from Fraunhofer Heinrich-Hertz-Institute, from Fraunhofer Institute for Photonic Microsystems and from Missing Link Electronics, PCI Express, and other protocols, can be transported in real-time at datarates of 10 Gbps, and more.
Security / Trusted Execution Environment and Functional Safety with Zync Ultrascale+ MPSoC / RFSoC
Presentation at the Workshop Programmable Processing for the Autonomous / Connected Vehicle 2019 in Neu-Ulm
The security of Embedded Systems has become a key concern, especially when hacked or tampered systems create safety issues and can harm people. In order to make an embedded system secure, CPU vendors like ARM offer the TrustZone technology. On top of this ARM TrustZone technology sits Open Portable (OP)-Trusted Execution Environment (TEE), an open source implementation of the TEE.
OP-TEE is a small secure operating system which, after authentication and description, gets loaded in an secured area in the memory. A Rich OS (e.g. Xilinx PetaLinux) driver can request, via a Secure Monitor Call, the execution of a trusted application. MLE took the effort to port OP-TEE to Xilinx Zync UltraScale+ MPSoC Platform, including device specific optimizations.

PXI Express over IP
Published article in the current edition of www.all-electronics.de.
PXI Express over IP allows the connection of PXI-Modules with existing ethernet networks. It is based on the technology of Fraunhofer HHI for processing TCP/IP via FPGA-logic. With this technology it is possible to transmit PCIe-Transaction-Layer-Packages over TCP/IP. The following implementation shows the proof of concept.
PXI Express over IP ermöglicht die Verbindung von PXI-Modulen über vorhandene Ethernet-Netze. Basierend auf der Technologie vom Fraunhofer HHI zur Verarbeitung von TCP/IP in FPGA-Logik werden PCIe-Transaction-Layer-Pakete über TCP/IP getunnelt. Eine beispielhafte Implementierung zeigt die Machbarkeit dieses Konzeptes.
