VLSi communication interface for time-triggered real.time systems M. LE~ H. GR• OVE This paper describes the design of a VLSI communication controller for the time-triggered protocol (TTPIC) as the result of a microelectronics development project done at Carinthia Tech Institute in cooperation with industrial partners. 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-wireo We applied a VHDL-based design flow to implement digital standard cell Iogic, RAMs, flash memory and analog cells into a 27 mm 2 chip using 0.35 ~ CMOS technology. First fully-tested production samples are available and proved the design to be first time right. At this year's SAE (Society of Automotive Engineers) World Congress in Detroit, from more than 5000 innovative products presented, the TTP controller IC was nominated as 'Top Product of the Year'.
Integrierter Kommunikationskontroller fª zeitgesteuerte Systeme. Dieser Beitrag pr~sentiert das Design eines integrierten Kommunikationskontroflers fª das 7imetriggered-Protokoil (TTP/C) als Ergebnis eines Entwicklungsprojekts, das an der Fachhochschule Technikum Karnten mit Industriepartnern durchgefª wurde. TTP/C ist ein neues Kommunikationsprotokoll fª fehlertolerante Echtzeitsysteme. Typische Anwendungen sind sicherheitskritische digitale Steuersysteme wie drive-by-wire und fly-by-wire. Das VHDL-Design vereinigt digitale Standardzellen, RAMs, Flash-Speicher und analoge Zellen auf 27 mrrF Chipflache in einer O,35-F-CMOS-Technologie.Erste getestete Muster sind verfª und best~tigen die volle Einhaltung der Spezifikation. Auf dem diesjahrigen Weitkongress fª Autoentwickler, der SAE-Show (Society of Automotive Engineers) in Detroit wurde aus ª 5000 Produktneuvorstellungen der TTP Controller-Chip als ,, Topprodukt des Jahres" ausgezeichnet.

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 0.35µ Flash-CMOS technology is used. Fully tested samples are already available and proved the design to be "first time right".
This paper describes the design of multirate filters used for the sample rate reduction of digital signals and their implementation on mixed-signal integrated circuits. Reaching target specifications of power, speed and silicon area as well as realizing multi-mode operation presents challenges. Possible solutions are discussed particularly for those filter stages which operate at the high sample rates and are illustrated in examples.
Entwurf von Multiratenfiltern für gemischt analog-digitale ICs.
Dieser Artikel beschreibt den Entwurf von Multiratenfiltern zur Reduktion derTaktrate digitaler Signale in gemischt analog-digitalen ICs. Die Realisierung von Systemanforderungen im Bereich der Leistungsaufnahme, der Taktrate und Siliziumfläche sowie eines MultimodeBetriebs stellt dabei eine besondere Herausforderung dar. Lösungsansätze speziell für jene Filterstufen, die mit den hohen Taktraten arbeiten, werden anhand von Beispielen beschrieben.
