摘要: 串行传输技术具有更高的传输速率和更低的设计成本, 已成为业界首选, 被广泛应用于高速通信领域。提出了一种新的高速串行传输接口的设计方案, 改进了Aurora 协议数据帧格式定义的弊端, 并采用高速串行收发器Rocket I/O, 实现数据率为2.5 Gbps的高速串行传输。关键词: 高速串行传输; Rocket I/O; Aurora 协议 为促使FPGA 芯片与串行传输技术更好地结合以满足市场需求, Xilinx 公司适时推出了内嵌高速串行收发器RocketI/O 的Virtex II Pro 系列FPGA 和可升级的小型链路层协议———Aurora 协议。Rocket I/O支持从622 Mbps 至3.125 Gbps的全双工传输速率, 还具有8 B/10 B 编解码、时钟生成及恢复等功能, 可以理想地适用于芯片之间或背板的高速串行数据传输。Aurora 协议是为专有上层协议或行业标准的上层协议提供透明接口的第一款串行互连协议, 可用于高速线性通路之间的点到点串行数据传输, 同时其可扩展的带宽, 为系统设计人员提供了所需要的灵活性[4]。但该协议帧格式的定义存在弊端,会导致系统资源的浪费。本文提出的设计方案可以改进Aurora 协议的固有缺陷,提高系统性能, 实现数据率为2.5 Gbps 的高速串行传输, 具有良好的可行性和广阔的应用前景。

Open Source for the Enterprise Open source software is changing the world of Information Technology. But making it work for your company is far more complicated than simply installing a copy of Linux. If you are serious about using open source to cut costs, accelerate development, and reduce vendor lock-in, you must institutionalize skills and create new ways of working. You must understand how open source is different from commercial software and what responsibilities and risks it brings. Open Source for the Enterprise is a sober guide to putting open source to work in the modern IT department.

C++ Network Programming, Volume 2, focuses on ACE frameworks, providing thorough coverage of the concepts, patterns, and usage rules that form their structure. This book is a practical guide to designing object-oriented frameworks and shows developers how to apply frameworks to concurrent networked applications. C++ Networking, Volume 1, introduced ACE and the wrapper facades, which are basic network computing ingredients. Volume 2 explains how frameworks build on wrapper facades to provide higher-level communication services.

Design patterns are elegant, adaptable, and reusable solutions to everyday software development problems. Programmers use design patterns to organize objects in programs, making them easier to write and modify. C# Design Patterns: A Tutorial is a practical guide to writing C# programs using the most common patterns. This tutorial begins with clear and concise introductions to C#, object-oriented programming and inheritance, and UML diagrams. Each chapter that follows describes one of twenty-three design patterns, recommends when to use it, and explains the impact that it will have on the larger design. The use of every pattern is demonstrated with simple example programs. These programs are illustrated with screen shots and UML diagrams displaying how the classes interact. Each of these programs is available on the companion CD-ROM and can be run, examined, edited, and applied.
