High volume USB 2.0 devices will be designed using ASIC technology with embedded USB 2.0 support. For full-speed USB devices the operating frequency was low enough to allow data recovery to be handled in a vendors VHDL code, with the ASIC vendor providing only a simple level translator to meet the USB signaling requirements. Today s gate arrays operate comfortably between 30 and 60 MHz. With USB 2.0 signaling running at hundreds of MHz, the existing design methodology must change.

This book is intended as a thorough introduction to both PCI and PCI-X. Is as a “companion” to the specifications. If you’re designing boards or systems using offthe-shelf PCI interface silicon, this book together with the silicon vendor’s data sheets should be sufficient for your needs. On the other hand, if your goal is to design PCI silicon, motherboards or backplanes, you will undoubtedly need to reference the specifications for additional detail.

Java technology has evolved from a programming language designed to create machine-independent embedded systems into a robust, vendor-independent, machine-independent, server-side technology, enabling the corporate community to realize the full potential of web-centric applications. Java began with the release of the Java Development Kit (JDK). It was obv

3 Dimensions TV (3DTV) became commercially available in the United States in 2010 and service in other countries was expected to follow soon thereafter. 3DTV is a subset of a larger discipline known as 3D Video (3DV). There are now many routine vendor announcements related to 3DTV/3DV, and there are also conferences wholly dedicated to the topic.

The following sections profile many of the vendors in the NFV market. The individual profiles were created through a collaborative effort between SDNCentral’s Research Team and the vendor’s product experts. SDNCentral worked under the assumption the information provided by the vendors was factual, auditing the submissions only to remove unverifiable claims and hyperbole. Extended profiles can be viewed online. While every attempt has been made to validate the capabilities listed in the profiles, SDNCentral advises end users to verify the veracity of each claim for themselves in their actual deployment environments. SDNCentral cannot be held liable for unexpected operations, damages or incorrect operation due to any inaccuracies listed here. SDNCentral welcomes feedback and additional information from end users based on their real-world experiences with the products and technologies listed. The SDNCentral research team can be reached at

This book intends to prepare you to define Unified Communications (UC) for yourself and then get it to work for you. Each vendor pulls together from its available products a package of features related to voice, data, messaging, and image communications. That’s UC for one vendor, but it’s unlikely to match exactly the UC from another vendor. You need a detailed specification to know what you’ll see installed.

一、DeviceNet概述DeviceNet 规范由Rockwell 自动化公司开发，并将其作为一个基于 CAN协议的开放式现场总线标准而公布。最初的 DeviceNet产品在1995年初出现。DeviceNet协议特别为工厂自动控制而定制，它在美国和亚洲扮演了非常重要的角色。在欧洲，越来越多的系统方案使用 DeviceNet来实现。ODVA（Open DeviceNet vendor Association）是所有DeviceNet产品开发者的组织，它成立于 1995年，并获得了Rockwell 自动化公司所有知识产权的转让。该组织按照公司的原则进行运作，并确保所有成员都有同等的发言权。它负责DeviceNet标准的制定和更新。此外，ODVA还致力于DeviceNet在全球的推广和市场化。开发基于DeviceNet的产品必须遵循 DeviceNet规范。DeviceNet规范分Volume 1，Volume Il两部分。用户可以从ODVA协会寻找关于 DeviceNet开发源代码的信息：基于 CAN-bus的硬件则可以从 PHILPS.Intel等半导体供货商那里获得
