英特尔新出版的书籍
"This is an essential guide to working with the
Intel® Atom™ processors that should be read by
anyone who wants to understand how to use the
platform effectively. The book covers key
concepts including power management, parallel
applications, and machine virtualization, while
providing a clear explanation of the system
architecture and how to use it to its fullest
advantage."

总结
• 嵌入式市场是高度细分的市场。为满足不同应用的需求,
处理器设计要在集成性和灵活性间进行平衡。
• 英特尔凌动™ 处理器E6xx 系列是第一款专为嵌入式应用
设计的凌动™ 处理器。
• 除了高度集成化外,首次将PCI Express技术应用到处理器
与IOH间的接口。
• 可以从多种IOH中选出最适合你的IOH,或设计自己的IOH
。
• 英特尔凌动™ 处理器E6xx 系列的高度集成性和灵活性使
得设计智能的嵌入式互联设备更简单,更便捷。
