A piece of custom-designed hardware in a chip. 专用集成电路。

一个在一个芯片上定制设计的硬件 address bus (地址总线)A set of electrical lines connected to the processor and all of the peripherals withwhich itcommunicates. The address bus is used by the processor to select aspecific memory location or register within a particular peripheral. If the address bus contains n electrical lines, the processor can uniquely address up to 2^n such locations. 一个连接处理器与全体外设的，用来通讯的电子线路集地址总线被 处理器用来选择在特定外设中的存储器地址或寄放器假设地址总线有n条电子 线路，处理器能唯一寻址高达2^n的地址空间 application software(应用软件) Describes software modules specific to a particular embedded project. The application software is unlikely to be reusable across embedded platforms, simply because each embedded system has a different application. 用来描述一个特定的嵌入式工程中的某一软件模块。

应用软件不象可 重用的交错嵌入式平台，只是由于每一个嵌入式系统有不同的应用软件 assembler(汇编编译器) A software development tool that translates human-readable assembly language programs into machine-language instructions that the processor can understandand execute. 一个能把人可读的汇编语言程序转换四处理器可理解和运行的机器 指令的软件开发工具 assembly language(汇编语言) A human-readable form of a processor"s instruction set. Most processor-specific functions must be written in assembly language. 一种人可读的处理器指令集的形式大多数处理器相关的功能务必用 汇编语言编写 B BSP(板卡支持包) See board support package. 见board support package。

binary semaphore(二元信号) A type of semaphore with just two states. Also called a mutex. 一种只有两种状态的信号也叫互斥信号 board support package(板卡支持包) Part of a software package that is processor or platform-dependent. Typically, sample source code for the board support package is provided by the package developer. The sample code must be modified as necessary, compiled, and linked with the remainder of the software package. 软件包的具有平台凭借性的那一片面典型地，板卡支持包的样例源 程序由包开发者供给样例源程序务必能在需要时被修改、编译并与软件包的剩 下的片面连接起来 bond-out processor (外合处理器) A special version of a processor that has some of the internal signals brought out to external pins. A bond-out processor is most often found within an emulator and is never intended to be used in a production system. 一种特殊版本的处理器，它有一些，内部的信号能传达成外置的针脚 上。

一个外合处理器绝大多数处境下只用在模拟器上，从来不会被特意用在产品 系统上 Breakpoint (断点) A location in a program at which execution is to be stopped and control of the processor switched to the debugger. Mechanisms for creating and removing breakpoints are provided by most debugging tools. 一个在程序中的地址，在那里程序的执行被中断，并且处理器的操纵 转换到了除错程序大多数除错工具供给增加与删除一个断点的机制 C CISC(繁杂指令集计算机) Complex Instruction Set Computer. Describes the architecture of a processor family. CISC processors generally feature variable-length instructions, multiple addressing formats, and contain only a small number of general-purpose registers. Intel"s 80x86 family is the quintessential example of CISC. Contrast withRISC. 繁杂指令集计算机。

对一种处理器架构的描述CISC处理器一般产 生变长的指令，多种地址格式，并且仅仅有少量的通用寄放器Intel的80x86家 族是是典型的CISC处理器相对于RISC而言 CPU(中央处理器) Central Processing Unit. The part of a processor that executes instructions. 中央处理器处理器中执行指令的那一片面 Compiler(编译器) A software development tool that translates high-level language programs into the machine-language instructions that a particular processor can understand and execute. 把高级编程语言程序转换到只有特定的处理器能了解和执行的机器 指令的一种软件开发包 context (上下文) The current state of the processor"s registers and flags. 处理器当前的状态和标志。

context switch(上下文切换) The process of switching from one task to another in a multitasking operating system. A context switch involves saving the context of the running ask and restoring the previously-saved context of the other. The piece of code that does this is necessarily processor-specific. 在多任务操作系统中我一个任务切换到另一个的过程上下文切换包 括保存正在运行的任务的上下文和恢复早先保存的另一个任务的上下文做这个 工作的一段代码务必具有处理器特权 counting semaphore(计数信号) A type of semaphore that is used to track multiple resources of the same type. An attempt to take a counting semaphore is blocked only if all of the availableresources are in use. Contrast with binary semaphore. 一种用来跟踪多个一致类型资源的信号灯。

仅仅在全体可用的资源都 被用完了时才阻塞相对二元信号而言 critical section(临界段) A block of code that must be executed in sequence and without interruption to guarantee correct operation of the software. See also race condition. 一段务必按次序执行的代码，并且不能被中断，否那么不能保证软件正 确地操作参照：竞争状况 cross-compiler(交错编译器) A compiler that runs on a different platform than the one for which it produces object code. A cross-compiler runs on a host compute。
