简单的 linux gpio 读写程序，了解2410 io操作。(Linux gpio read and write simple procedures, understand the operation of 2410 io.)

十六进制数转换工具,点选相应的位,可快速查看其相应的十六进制数,对寄存器地址计算很方便.(Hexadecimal conversion tool, click the corresponding bit, you can quickly see the corresponding hexadecimal number, calculated on the register address is very convenient)

AMBA总线规范，能对从事嵌入式的同行们有一些帮助，让大家更好的理解ARM 结构和AMBA 体系(AMBA Specification)

说明：  选用ZYNQ SoC作为智能相机系统的硬件处理平台，依据系统设计需求，将系统整体功能结构的开发划分到用户空间、内核空间、底层硬件三个层面。在硬件层，对系统硬件功能进行了模块化设计，分别对基于USB和OV7725的双通道图像采集模块、HDMI显示模块进行开发。(Zynq SOC is selected as the hardware processing platform of the intelligent camera system. According to the system design requirements, the development of the overall functional structure of the system is divided into three levels: user space, kernel space and bottom hardware. In the hardware layer, the hardware functions of the system are modularized, and the dual channel image acquisition module and HDMI display module based on USB and ov7725 are developed respectively.)

在linux平台下,纯c写的盲信号分离的代码.它采用基于卷积混合的盲信号分离算法,不但可以分离人工合成的混合信号,而且对于真实环境中的卷积混合的语音信号也能够分离.在本程序中,包含了两个测试文件,makefile后便可以直接使用. 另外值得一提的是,压缩包里包含有一些语音处理方面的常用函数.例如fft变换,读取写入wav文件,以及一些常用的一维向量和二维矩阵变换的函数.这些可以直接应用在其他应用程序里去.(Linux platform, the blind signal separation of pure c write code. Blind signal separation algorithm based on convolution mixed, can be separated not only synthetic mixed-signal and voice signal convolution mixed in real environment can separation in the program, contains two test files can directly use the makefile after. Also worth mentioning is that the compressed bundle includes voice processing commonly used functions such as fft transform read write wav file, as well as some of the commonly used one-dimensional vector and two-dimensional matrix transform function. these can be applied directly into other applications.)

嵌入式系统开发与应用 北航的ppt课间(embedded system development and application of the Beijing University of Aeronautics and Astronautics ppt break-time)

说明：  U-Boot不仅仅支持嵌入式Linux系统的引导，它还支持NetBS D, VxWorks, QNX, RTEMS, ARTOS, LynxOS, android嵌入式操作系统。其目前要支持的目标操作系统是OpenBSD, NetBSD, FreeBSD,4.4BSD, Linux, SVR4, Esix, Solaris, Irix, SCO, Dell, NCR, VxWorks, LynxOS, pSOS, QNX, RTEMS, ARTOS, android。这是U-Boot中Universal的一层含义，另外一层含义则是U-Boot除了支持PowerPC系列的处理器外，还能支持MIPS、 x86、ARM、NIOS、XScale等诸多常用系列的处理器。这两个特点正是U-Boot项目的开发目标，即支持尽可能多的嵌入式处理器和嵌入式操作系统。就目前来看，U-Boot对PowerPC系列处理器支持最为丰富，对Linux的支持最完善。其它系列的处理器和操作系统基本是在2002年11 月PPCBOOT改名为U-Boot后逐步扩充的。从PPCBOOT向U-Boot的顺利过渡，很大程度上归功于U-Boot的维护人德国DENX软件工程中心Wolfgang Denk[以下简称W.D]本人精湛专业水平和执着不懈的努力。(U-boot not only supports the boot of embedded Linux system, but also supports netbs D. VxWorks, QNX, RTEMS, Artos, lynxos, Android embedded operating system. The current target operating systems to be supported are OpenBSD, NetBSD, FreeBSD, 4.4BSD, Linux, SVR4, ESIX, Solaris, IRIX, SCO, Dell, NCR, VxWorks, lynxos, PSOs, QNX, RTEMS, Artos, Android. This is the meaning of universal in u-boot. The other meaning is that u-boot supports not only PowerPC series processors, but also MIPs, x86, arm, NIOS, Xscale and many other commonly used series processors. These two characteristics are exactly the development goal of the u-boot project, that is to support as many embedded processors and embedded operating systems as possible. At present, u-boot has the richest support for PowerPC series processors and the most perfect support for Linux.)
