电源技术 DN464 高效率USB电源管理系统
 
Automotive power systems are unforgiving electronicenvironments. Transients to 90V can occur when thenominal voltage range is 10V to 15V (ISO7637), along withbattery reversal in some cases. It’s fairly straightforwardto build automotive electronics around this system, butincreasingl ...

单片机编程 开放式汇编器系统的设计
汇编器在微处理器的验证和应用中举足轻重，如何设计通用的汇编器一直是研究的热点之一。本文提出了一种开放式的汇编器系统设计思想，在汇编语言与机器语言间插入中间代码CMDL（code mapping description language）语言，打破汇编语言与机器语言的直接映射关系，由此建立起一套描述汇编语言与机器语言的开放式映射体系。基 ...

加密解密 DES(Data Encrypton Standard) 算法的实现网上已经有很多
DES(Data Encrypton Standard) 算法的实现网上已经有很多，本人在此讲述的是在DES算法加密过程中如何查看16迭代过程中生成的Ki,Li,Ri,Fi,Si等，这样可以当做一个DES加密对照器，这样可以方便的发现你在加密过程中出现的错误!
