NUC505 采用DSP指令做快速傅里叶变换。理论上指令部分是Cortex-M4F 系列通用的。(NUC505 use dsp do fft. )

S3C2440完全开发流程，很详细的教程(S3C2440 fully developed flow, a very detailed tutorial 英语 中文 德语 检测语言 中文(简体) 英语 日语 S3C2440完全开发流程，很详细的教程 )

基于ARM7的开发板的外部存储器接口程序，文件里有程序的详细注释，对与在此基础之上的二次开发非常方便(based on the ARM7 development board external memory interface, document the procedures detailed notes, right and the basis of this second development is very convenient)

ARM 开发工程师入门宝典，对于初学者在面 对一个嵌入式开发项目的时候，往往面临着诸多困难，如选择什么样的开发平台？什么样的器件类型？在进行编译时怎样实现代码优化？开发工具该如何选择和使用？在进行程序调试时应该注意那些问题以及选择什么样的嵌入式OS等等。希望通过本文，能帮助初学者了解有关ARM嵌入式系统开发流程。(ARM the development engineers Starter Collection, in the face of an embedded development project for beginners, are often faced with many difficulties, such as the choice of what kind of development platform? What kind of device types? How to achieve during compile time code optimization? Development tools how to choose and use? During debugging should pay attention to those issues, and choose what kind of embedded OS, and so on. I hope this article can help beginners Learn about ARM Embedded system development process.)
