The amount of electronic components used in airplanes is still rising. Additionally, the amount of information distributed and shared throughout the avionic network is increasing since applications more and more rely on information gathered from distributed systems.

Current avionic data networks like ARINC 429 and MIL-STD 1533 are not capable of handling the need for greater bandwidth. The new avionic full duplex switched Eth-ernet (AFDX) was designed to meet these requirements as well as the performance requirement, which may be raised in the future. AFDX is based on COTS Ethernet

components and therefore also fulfi lls the need of an affordable avionic data network solution.

The amount of electronic components used in airplanes is still rising. Additionally, the amount of information distributed and shared throughout the avionics network is increasing since applications more and more rely on information gathered from distributed systems.

Current avionic data networks like ARINC 429 and MIL-STD 1533 are not capable of handling the need for greater bandwidth. The new avionics ARINC-664 standard – also know as Avionics Full Duplex switched Ethernet (AFDX®) – was designed to meet these requirements as well as the perfor-mance requirements, which may be raised in the future. SYSGO’s Safety-Critical Ethernet

implementation of ARINC-664 part. 7 is based on COTS Ethernet components and therefore also fulfi lls the need of an afford-able avionics data network solution.

gauge. The sensor information gathered in this demo is the rotation of a helicop-ter rotor. This rotary speed is acquired by a PikeOS driver running in the ARINC 653 compliant environment of PikeOS. An aver-age rotary speed value is calculated which is frequently written to an ARINC 653 sam-pling port. This sampling port is connected to the ARINC-664Node which sends the rotary speed parameter through an ARINC-664 network to a Linux PC that also includes SYSGO’s Safety-Critical Ethernet stack. The Linux incorporated Idata from Quantum3D which displays a speed gauge, is visualizing the rotor speed.

About SYSGO’s Safety-Critical Ethernet SoftwareSYSGO’s Safety-Critical Ethernet software is the first of its kind to be introduced to the marketplace. It is a highly optimized software-only implementation of the ARINC-664 part.7 specification. It com-pletely conforms to the ARINC-664 speci-fication and also implements extensions and enhancements from Boeing and Airbus. SYSGO’s Safety-Critical Ethernet can be used as a stand-alone stack for high performance requirements, or with an RTOS that con-forms to the specifications of ARINC 653. SYSGO’s Safety-Critical Ethernet consists of the ARINC-664 node implementation and a small-footprint host driver. Currently sup-ported host operating systems are PikeOS, SYSGO’s own ARINC 653 compliant real-time operating system for safety-critical applica-tions, as well as LynxOS-178, and VxWorks. SYSGO’s Safety-Critical Ethernet software solution is the only ARINC-664 implementa-tion that incorporates ICMP and SNMP on the ARINC-664 node. Therefore, the behav-ior of the node is non-intrusive in respect to the host. Unlike other ARINC-664 solutions, with SYSGO’s Safety-Critical Ethernet the host system has no performance deficit.

About Safety-Critical Ethernet/ARINC-664Safety-Critical Ethernet is compliant to ARINC-664 part. 7, a specification for a deterministic aircraft data network bus for aeronautical, railway and military systems. The network is based on standard IEEE 802.3 Ethernet technology. The benefits from using commercial-off-the-shelf (COTS) Ethernet components include reduced

overall costs, faster system development and less-costly maintenance for the system network. Hardware components, cables, and test equipment for Ethernet are field proven and much more affordable than “built-to-spec” avionics solutions. Standard commer-cial grade Ethernet won’t meet avionics net-work requirements. Therefore, ARINC-664 extends the Ethernet standard by adding Quality of Service (QoS) and deterministic behavior with a guaranteed dedicated band-width. This avionics data network was first used in the Airbus A380 and A400M. Airbus and Boeing plan to use Safety-Critical Ether-netin future developments.

About SYSGOSYSGO is specialized in design, implementa-tion and configuration of device software for the embedded market. Besides SYSGO’s real-time operating system solution for safety-critical systems, PikeOS, and the Embedded Linux development environment, ELinOS, SYSGO offers the development of device drivers, board support packages and firmware. SYSGO supports its customers with services for Embedded Linux, real-time and certification for safety-critical applica-tions. The target markets are Aerospace & Defense, Industrial Automation, Automo-tive, Consumer Electronic and Network Infrastructure. SYSGO’s customers include DaimlerChrysler, EADS Airbus, EADS Mili-tary Air Systems, Honeywell, IBM, Raytheon, Rheinmetall, Rockwell-Collins and Rohde & Schwarz. SYSGO AG was founded in Mainz, Germany, in 1991 and was reincorporated as a joint stock company in October 2002. The company has six facilities in Germany and Europe and provides a global distribution network.
