TTA-C2 a single chip communication controller for the time-triggered-protocol

This paper describes the architecture and implementation of the first industrial single chip communication controller for the Time Triggered Protocol (TTP/C). TTP/C is an emerging communication protocol for fault-tolerant real time systems. Typical applications are safety-critical digital control systems such as drive-by-wire and fly-by-wire. We applied a VHDL based design flow to implement an application specific RISC core with several specialized peripheral blocks, RAMs, flash memory and analog cells. For production of the 27 mm² chip a 0.35 μ Flash-CMOS technology is used Fully tested samples are already available and proved the design to be "first time right".
