本书从软件设计的角度，全面、系统地介绍了arm处理器的基本体系结构和软件设计与优化方法。内容包括：arm处理器基础；arm/thumb指令集；c语言与汇编语言程序的设计与优化；基本运算、操作的优化；基于arm的dsp；异常与中断处理；固件与嵌入式os；cache与存储器管理；armv6体系结构的特点等。全书内容完整，针对各种不同的arm内核系统结构都有详尽论述，并有大量的例子和源代码。附录给出了完整的armv4/v5/thumb指令的功能、编码、周期定时以及汇编参考。 (This book from the perspective of software design, comprehensive and systematic introduction to the basic arm processor architecture and software design and optimization methods. Include: arm processor based arm/thumb instruction set c language and assembly language program design and optimization basic operations, operations optimization on the arm of the dsp exception and interrupt handling firmware and embedded os cache and memory management armv6 architecture characteristics. Complete contents of the book, for a variety of arm-core system architecture are discussed in detail, and a large number of examples and source code. The appendix gives a complete armv4/v5/thumb instructions, coding, cycle time and assembly reference.)

使用JAVA I/O和 NI/O编写的两种网络ECHO服务器，用以学习两种IO的不同编程方法，体验基于阻塞与非阻塞IO开发高性能网络应用程序的具体实例.Java平台传统的I/0系统基于byte(字节)和Stream(数据流)。这种模式下的I/O 操作以字节为单位,以流的方式处理数据。而NIO( New I/O )以块的方式处理数据，它的系统操作面向Buffer(缓冲),Channel(通道)和Selector(选择器)，不再是字节，这种模式利用了操作系统管理内存和文件的方式，并将一些耗时操作直接转移给操作系统，使JavaI/O的速度得以提高、性能得到了明显的改善 -The use of JAVA I/O and NI/O, prepared by two types of network servers ECHO to learn two different programming methods IO experience obstructive and non-blocking IO based on the development of high-performance network applications specific examples. Java platform for the traditional I/0 system is based on the byte (byte) and Stream (data streams). This mode of I/O operation in bytes in order to deal with data flow way. The NIO (New I/O) blocks the way to deal with data, its system for Buffer (buffer), Channel (channel) and the Selector (selector), is no longer a byte, this mode of use of operating system management of memory and the manner in which documents, and some time-consuming operation of a direc
