Software-based AFDX is more portable

Sysgo has released the first pure software implementation of AFDX available on the market.

Sysgo, the European vendor for safety critical COTS software, today announced the release of a software-only implementation for AFDX (ARINC-664), the first pure software implementation of AFDX available on the market.

Sysgo's AFDX software solution will undergo DO178B Level B certification.

"This is another milestone to strengthen our position as a major vendor of safety critical COTS software in Europe".

"Since the US avionics market also focuses on AFDX, this is the next step that will allow Sysgo to emerge in the US market with a widely needed product", says Detlev Schaadt, CTO of Sysgo.

The software implementation of AFDX offers design possibilities that hardware solutions can not provide.

Software AFDX is portable, more flexible and much more affordable compared with the currently used ASICs.

Portable AFDX consists of the AFDX node implementation and the very small foot-printed host driver.

ICMP and SNMP run on the AFDX node not on the host.

The configuration of the AFDX node can be done through the host driver which uses a XML based VCT (virtual channel table).

This flexibility enables Portable AFDX to be used in several environments, only by changing the configuration.

Sysgo's software AFDX avoids the high design risks and extensive development costs of a hardware solution and provides the opportunity to incorporate customer ideas and to be ready for future challenges.

The reference implementation is based on a PowerQUICC II PMC module.

Sysgo provides drivers for its own PikeOS RTOS, LynxOS-178 (LynuxWorks) and Linux.

However, there are no limitations for using other safety critical RTOSs.
