嵌入式系統(tǒng)常用詞匯統(tǒng)計表 

A

ASIC（專用集成電路）
Application-Specific Integrated Circuit. A piece of custom-designed hardware in a chip.
專用集成電路。一個在一個芯片上定制設(shè)計的硬件。

address bus （地址總線）
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.
一個連接處理器與所有外設(shè)的，用來通訊的電子線路集。地址總線被處理器用來選擇在特定外設(shè)中的存儲器地址或寄存器。如果地址總線有n條電子線路，處理器能唯一尋址高達(dá)2^n的地址空間。

application software（應(yīng)用軟件）
Describes software modules specific to a particular embedded project. Theapplication software is unlikely to be reusable across embedded platforms, simplybecause each embedded system has a different application.

用來描述一個特定的嵌入式項目中的某一軟件模塊。應(yīng)用軟件不象可重用的交叉嵌入式平臺，只是因為每一個嵌入式系統(tǒng)有不同的應(yīng)用軟件。

assembler（匯編編譯器）
A software development tool that translates human-readable assembly languageprograms into machine-language instructions that the processor can understandand execute.
一個能把人可讀的匯編語言程序轉(zhuǎn)換到處理器可理解和運(yùn)行的機(jī)器指令的軟件開發(fā)工具。

assembly language（匯編語言）
A human-readable form of a processor"s instruction set. Most processor-specific functions must be written in assembly language.
一種人可讀的處理器指令集的形式。大多數(shù)處理器相關(guān)的功能必須用匯編語言編寫。

B
BSP（板卡支持包）
See board support package.
見board support package。

binary semaphore(二元信號)
A type of semaphore with just two states. Also called a mutex.
一種只有兩種狀態(tài)的信號。也叫互斥信號。

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. 
軟件包的具有平臺依賴性的那一部分。典型地，板卡支持包的樣例源程序由包開發(fā)者提供。樣例源程序必須能在需要時被修改、編譯并與軟件包的剩下的部分連接起來。

bond-out processor （外合處理器）
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. 
   一種特殊版本的處理器，它有一些，內(nèi)部的信號能傳達(dá)到外置的針腳上。一個外合處理器絕大多數(shù)情況下只用在模擬器上，從來不會被特意用在產(chǎn)品系統(tǒng)上。

Breakpoint （斷點(diǎn)）
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.
   一個在程序中的地址，在那里程序的執(zhí)行被停止，并且處理器的控制轉(zhuǎn)換到了除錯程序。大多數(shù)除錯工具提供增加與刪除一個斷點(diǎn)的機(jī)制。

C
CISC（復(fù)雜指令集計算機(jī)）
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 with RISC. <<容~源~電~子~網(wǎng)~版權(quán)聲明：本站內(nèi)容部分來源于網(wǎng)絡(luò)，如侵犯到你的權(quán)利請及時與我們聯(lián)系更正，聯(lián)系QQ:316520686。
