intertask communication（进程间通讯）
A mechanism used by tasks and interrupt service routines to share information and synchronize their access to shared resources. The most common building blocks of intertask communication are semaphores and mutexes. 
一种被用来在任务和中断服务程序之间共享信息和同步它们对共享资源访问的机制。大部分进程间通讯的建立的基石是信号灯和互斥。

K
Kernel（内核）
An essential part of any multitasking operating system, the kernel contains just the scheduler and context-switch routine.
任何多任务操作系统的本质部分，内核仅仅包含调度程序和上下文切换进程。

L
Linker（连接程序）
A software development tool that accepts one or more object files as input and outputs a relocatable program. The linker is thus run after all of the source files have been compiled or assembled.
一种能把一个或更多目标文件组合成可输入和输出的可重定位程序的开发工具。连接程序在所有的源文件都被编译或汇编之后运行。

Locator（定位程序）
A software development tool that assigns physical addresses to the relocatable program produced by the linker. This is the last step in the preparation of software for execution by an embedded system and the resulting file is called an executable. In some cases, the locator"s function may be hidden within the linker.
一种分配物理地址给连接程序处理过的可重定位程序的软件开发工具。这是准备一个软件在嵌入式系统中运行的最后一步，并且结果文件叫做可执行的。在一些情况下，定位程序功能隐藏在连接程序中。

logic analyzer（逻辑分析仪）
A hardware debugging tool that can be used to capture the logic levels (0 or 1) of dozens, or even hundreds, of electrical signals in real-time. Logic analyzers can be quite helpful for debugging hardware problems and complex processor-peripheral interactions.
一种硬件调试工具，能捕获实时电信号的许多逻辑电平（0或1），逻辑分析仪在调试硬件问题和复杂的处理外设交互时相当有用。
