前言: 最近看了google的工程师写的一个非常简单的垃圾收集器,大概200多行C代码,感叹大牛总能够把复杂的东西通过很简单的语言和代码表达出来.为了增加自己的理解,决定把大牛的想法和代码分析一遍,与大家分享,顺便结合wikipedia,复习下GC的基本概念. 相信大家在写程序的过程中都遇到内存管理的问题,诸如malloc/delete.new/free等,C/C++需要程序员主动进行内存的释放,即垃圾内存的回收,而像Java就提供了GC机制来自动进行垃圾回收. 一.垃圾与垃圾回收 为什么需要进…

具有开漏(OD)输出的器件是指内部输出和地之间有个N沟道的MOSFET(T1),这些器件可以用于电平转换的应用.输出电压由Vcc'决定.Vcc'可以大于输入高电平电压VCC(up-translate)也可以低于输入高电平电压VCC(down-translate). 开漏器件对于各种电压节点间的电平转换非常有用.但是,这种电平转换的方法存在一些缺点.例如,当输出电平为低时,N沟道三极管是导通的,这样在Vcc'和GND之间有一个持续的电流流过上拉电阻Rpullup和三极管T1.这会影响整个系统的功耗…
