Com o crescimento acelerado da complexidade das aplicações e softwares que exigem alto desempenho, o hardware e sua arquitetura passou por algumas mudanças para que pudesse atender essa necessidade. Uma das abordagens propostas e desenvolvidas para suportar essas aplicações, foi a integração de mais de um core de processamento em um único circuito integrado. Inicialmente, a comunicação utilizando barramento foi escolhida, pela sua vantagem de reuso comparado a ponto a ponto. No entanto, com o aumento acelerado da quantidade de cores nos Systems-on-Chip (SoC), essa abordagem passou a apresentar problemas para suportar a comunicação interna. Uma alternativa que vem sendo explorada é a Network-on-Chip (NoC), uma abordagem que propõe utilizar o conhecimento de redes comuns em projetos de comunicação interna de SoC. Esse trabalho fornece uma arquitetura de NoC completa, configurável, parametrizável e no padrão Ethernet. Os três módulos básicos da NoC, Network Adapter (NA), Link e Switch, são implementados e disponibilizados. Os resultados foram obtidos utilizando o FPGA Stratix IV da Altera. As métricas de desempenho utilizadas para validação da NoC são a área no FPGA e o atraso na comunicação. Os parâmetros disponibilizados são referentes as configurações dos módulos desenvolvidos, considerando características apresentadas de aplicações DSP (Digital Signal Processing). O experimento utilizando dois NAs, dois cores e um Switch precisou de 7310 ALUTs do FPGA EP4SGX230KF40C2ES o que corresponde a 4% dos seus recursos lógicos. O tempo gasto para a transmissão de um quadro ethernet de 64 Bytes foi de 422 ciclos de clock a uma frequência de 50MHz. / With the accelerated growth of the complexity of the software and applications that require high performance, hardware and its architecture has undergone a few changes so it could meet that need. One of the proposals and approaches developed to support these applications, was the integration of more than one core processing in a single integrated circuit. Initially, the bus communication architecture was chosen, using for its reuse benefit compared to point-to-point. However, with the cores number increase in Systems-on-Chip (SoC), this approach began to present problems to support internal communication. An alternative that has been explored is the Network-on-Chip (NoC), an approach that proposes to use knowledge of common networks on internal communication projects of SOC. This dissertation focuses is to provide a complete NoC architecture, configurable, customizable and on standard Ethernet. The three NoC basic modules, Network Adapter (NA), Link and Switch, are implemented. The results were obtained using the Stratix IV FPGA. The performance metrics used for NoC validation are silicon area and latency. The available parameters are related to developed modules settings, considering features presented of DSP applications. The experiment using two NA, two cores and one Switch needed 7310 FPGA ALUTs which corresponds to 4% of their logical resources. The time for the transmission of an ethernet frame of 64 Bytes was 422 clock cycles at 50 MHz.

In dieser Arbeit wird ein Applikationstool auf Basis des Kommunikationsprotokolls XCP entwickelt. Dieses verwendet die Ethernet-Transportschicht, um den Test von Steuergerätesoftware zu optimieren. Hierzu bietet das Applikationstool eine Schnittstelle an, die es Testautomatisierungslösungen ermöglicht, Variablen des Steuergeräts zu kalibrieren und per Polling oder synchroner Messung abzurufen. Aufgrund der hohen Performance, den geringen Entwicklungskosten und der guten Anwendbarkeit in der Testautomatisierung hebt sich das entwickelte Applikationstool von anderen auf dem Markt verfügbaren Tools ab. Zudem kann das Tool flexibel erweitert und auf die individuellen Bedürfnisse der Anwender angepasst werden. Die Architektur wird auf Grundlage wichtiger Design-Patterns erstellt, wodurch verschiedene Protokoll- und Hardware-Komponenten in einer abstrakten Weise dargestellt und miteinander verbunden werden können. Zuvor werden alle benötigten Daten aus den sogenannten A2L-Dateien ausgelesen, indem reguläre Ausdrücke und Grammatiken angewandt werden. Durch die entwickelte Architektur können ältere, aktuelle und auch zukünftige Steuergeräte zuverlässig ausgelesen werden. Des Weiteren erlaubt die Software-Struktur das flexible Hinzufügen verschiedener Hardware-Adapter und weiterer Kommunikationsprotokolle. Zur Evaluierung werden die einzelnen Komponenten mit realen Steuergeräten getestet und bezüglich ihrer Geschwindigkeit überprüft. Bei der Messung mittels Polling wurde eine durchschnittliche Zeit von 0.3ms pro gemessenem Wert erreicht, wobei die Latenz des Steuergeräts ungefähr die Hälfte der Zeit beansprucht. Für die synchrone Messung konnte eine Verarbeitungsgeschwindigkeit von ca. 500 Bytes/ms erreicht werden, was selbst in kleinen Messrastern eine Verarbeitung vor dem Eintreffen des nächsten Wertes ermöglicht.

International Telemetering Conference Proceedings / October 18-21, 2004 / Town & Country Resort, San Diego, California / Serial interfaces (RS232, RS422/485) have been the standard method of communications in traditional data acquisition systems. The role of these interfaces has been to supply a simple setup and control path between a host and the data acquisition master and little else. Today’s distributed data acquisition systems (DAS), which are comprised of many types of components including Ground Support Computers (GSC), Pilot Control Units (PCU), Data System Control Units (DSCU), Solid State Recorders (SSR), Data Acquisition Units (DAU) and Cockpit Instrumentation Data Systems (CIDS), are ideally suited to the use of Ethernet for not only setup functions, but for the distribution of acquired data and status to an unlimited number of users. Besides the obvious advantage of higher data rates, Ethernet provides other benefits such as greater data integrity, multi-host capability, and common programming interfaces. This paper details the integration of new L3 Communications - Telemetry East (L3-TE) Ethernet based software and hardware components that are part of the Comanche Data Systems equipment suite.

ITC/USA 2008 Conference Proceedings / The Forty-Fourth Annual International Telemetering Conference and Technical Exhibition / October 27-30, 2008 / Town and Country Resort & Convention Center, San Diego, California / The iNET project was launched to foster network based instrumentation and telemetry.

This demonstration will be used as a learning exercise for the implementation of network technologies. Specifically this paper will explore the operational challenges that are expected to be encountered while performing the installation and in the use of the network based instrumentation and telemetry system.

ITC/USA 2006 Conference Proceedings / The Forty-Second Annual International Telemetering Conference and Technical Exhibition / October 23-26, 2006 / Town and Country Resort & Convention Center, San Diego, California / Network-centric data acquisition and telemetry systems continue to gain momentum and adoption. However, inherent non-deterministic network delays hinder these systems’ suitability for use where high-accuracy timing information is required. The emerging IEEE 1588 standard for time distribution offers the potential for real-time data acquisition system development using cost-effective, standards-based network technologies such as Ethernet and IP multicast. This paper discusses the challenges, realities, lessons, and triumphs experienced using IEEE 1588 in the development and implementation of such a large-scale network-centric data acquisition and telemetry system. IEEE 1588 clears a major hurdle in moving the network-centric buzz from theory to realization.

ITC/USA 2015 Conference Proceedings / The Fifty-First Annual International Telemetering Conference and Technical Exhibition / October 26-29, 2015 / Bally's Hotel & Convention Center, Las Vegas, NV / The network switch is a critical element in the flight test network. All devices in the network are configured, synchronised and managed via the switch. In addition to this all acquired data is routed through the switch. For these reasons, the flight test network switch has always needed to be rugged and reliable with high throughput and simple intuitive setup. Ethernet technology and the move towards open standards within FTI systems have enabled flight test networks to become increasingly flexible and heterogeneous. Modern FTI networks may have different synchronisation and data transmission protocols running simultaneously. It is also important to quickly switch network configurations for different flight profiles and to enable new features to be easily added to existing installations. This paper examines the increasing network interoperability and flexibility challenges and discusses how the network switch is best placed to provide solutions.
