TTP

The number of control units and the complexity of electronic networks are continuously increasing. Distributed functions require seamless integration and higher levels of safety and fault tolerance. The time-triggered communication protocol TTP has been designed to address these requirements and to reduce the complexity of distributed fault-tolerant architectures.

TTP is used in commercial applications since 2002. It enables reliable distributed computing and networking for modern vehicle systems at lower lifecycle costs. This modular control system platform technology supports efficient system reconfiguration, upgrades and growth.

SAE International is developing the SAE AS6003 aerospace standard that will help simplify the design of advanced integrated systems using time-triggered protocol (TTP).

Mature tools and standard components
TTTech's TTP-based solutions facilitate the design of high-integrity systems with deterministic behavior. By using a highly efficient set of tools and hardware and software components, development time can be reduced considerably. TTP has been employed and proven in demanding aerospace programs. Interfaces with 3rd party model-based development tools and customizable testing equipment are available.

TTP controllers
TTP controller chips are commercially obtainable since 1998 and can be sourced from austriamicrosystems and ON Semiconductor. TTP chip IP can be used for system-on-chip (SoC) FPGA designs of various suppliers as well.

More information on TTP can be found at TTA-Group website.
