ASU

ASU is presented as an Ancillary System Unit computer for embedded aircraft architectures. Its principal role is to concentrate data acquired through avionics interfaces such as ARINC 429 and CAN, then de-format and translate that information for other aircraft functions. The existing product record also identifies controlled management functions implemented in hardware and software intended for a safety-critical environment. SERMA Ingénierie’s current portfolio confirms its work on build-to-spec embedded electronic equipment, data interfaces and high-criticality aeronautical developments. Because a current public model-specific datasheet is not available, no processor, channel-count, environmental or certification value is claimed beyond the documented functional role.

Key capabilities

• Concentration of data from aircraft avionics interfaces
• ARINC 429 and CAN data acquisition
• De-formatting and translation between bus data and aircraft interfaces
• Embedded hardware and software management functions
• Designed for integration into safety-critical avionics architectures

Typical applications

Aircraft data concentration and interface-management functions in customized embedded avionics systems.
