BACKGROUND The embodiments relate to guest operating system integrity validation, and more particularly to guest operating system integrity validation through a virtual machine monitor (VMM) hypervisor trap. Today's computers make use of various memo…
A processor's performance state may be adjusted based on processor temperature. On transitions to a lower performance state due to the processor getting hotter, the processor's frequency is reduced prior to reducing the processor voltage. Thus, the p…
接口(Interface) 仍然从常识开始… 日常生活中有很多接口:电源插座:汽车油门… 那什么是接口? 连接两个东西.信号转换.屏蔽细节… Interface: electrical circuit linking one device with another and enabling data coded in one format to be transmitted in another( 出自牛津辞典) 什么是操作系统接口? 连接上层用户和操作系统软件 什么是操作系统接口? 都是命令吗…

操作系统(Operating System,OS) 是配置在计算机硬件上的第一层软件,是对计算机硬件系统的首次扩充,是一个计算机系统最基础,也是最重要的系统软件. 操作系统的作用 1 实现对计算机资源的抽象 2 作为用户与计算机硬件系统之间的接口 3 OS作为计算机系统资源的管理者: 在一个计算机系统中,通常都含有各种各样的硬件和软件资源.归纳起来可将资源分为四类:处理器.存储器.I/O设备以及信息(数据和程序).相应地,OS的主要功能也正是针对这四类资源进行有效的管理.因此,从这个角度来看,我…

No one can do all things, learn to be good at use what others already did. Most computers have two modes of operation: kernel mode and user mode. The OS is the most fundamental piece of software and runs in kermel mode(also called usperivosr mode). I…
A real time operating system (RTOS) for embedded controllers having limited memory includes a continuations library, a wide range of macros that hide continuation point management, nested blocking functions, and a communications stack. The RTOS execu…
