SAE International’s AS-2 Embedded Computing Systems Committee is developing a new aerospace standard that will help simplify the design of advanced integrated systems using time-triggered protocol (TTP), resulting in system life-cycle cost savings. TTP is one of the core technologies for design of open time-triggered architecture (TTA) and generic control system platforms for deterministic, modular, scalable, and reusable aerospace systems. TTA helps reduce system complexity and life-cycle costs in safety-critical, fault-tolerant, and distributed onboard systems. The AS6003 “TTP Communication Protocol” standard will protect past and ongoing system design investments and simplify design, system integration, and incremental modernization of open aerospace and defense systems and architectures, according to SAE. The AS-2 Embedded Computing Systems Committee addresses all facets of embedded computing systems—design, maintenance, and in-service experience. The committee is part of SAE International’s Avionic Systems Division.
