最新嵌入式系統|常用詞匯表1

EPROM（可擦的，可編程的只讀存儲器）
Erasable, Programmable Read-Only Memory. A type of ROM that can be erased by exposing it to ultraviolet light. Once erased, an EPROM can be reprogrammed with the help of a device programmer.
一種可用紫外線擦除的存儲器。一次擦除后，EPROM可以在設備編程器的幫助下被重編程。

embedded system（嵌入式系統）
A combination of computer hardware and software, and perhaps additional mechanical or other parts, designed to perform a dedicated function. In some cases, embedded systems are part of a larger system or product, as is the case of an anti-lock braking system in a car. Contrast with general-purpose computer. 
  計算機硬件和軟件的結合體，或許還加上機械等其他部分，被設計來完成專門的功能。在一些情況下，嵌入式系統是一個大的系統或產品的一部分，就象汽車上的防抱死裝置。與通用計算機相對。

Emulator(仿真器)
Short for In-Circuit Emulator (ICE). A debugging tool that takes the placeof-emulates-the processor on your target board. Emulators frequently incorporate a special "bond-out" version of the target processor that allows  you to observe and record its internal state as your program is executing
.  在線仿真器的簡寫。一個在你的目標板上放置仿真的處理器的調試工具。仿真器經常和一目標處理器的一種“外合”版本合在一起，這個版本的的處理器充許你運行程序時觀察和記錄它的內部狀態(tài)。

Executable（可執(zhí)行的）
A file containing object code that is ready for execution on the target. All that remains is to place the object code into a ROM or download it via a debugging tool. 
   一個包含準備在目標機上運行的目標代碼的文件。放置目標代碼到ROM中或通過調試工具下載。

F
Firmware（固件）
Embedded software that is stored as object code within a ROM. This name is most common among the users of digital signal processors.
是作為目標代碼存貯在ROM中的嵌入式軟件。這個名字在數字信號處理器的用戶中相當流行。

flash memory （閃存）
A RAM-ROM hybrid that can be erased and rewritten under software control. Such devices are divided into blocks, called sectors, that are individually-erasable. Flash memory is common in systems that require nonvolatile data storage at very low cost. In some cases, a large fash memory may even be used instead of a disk-drive.
   一種RAM-ROM的混血兒，它能在軟件的控制下被擦除和重寫。一些設備被分成叫段組的塊，能個別地可擦。閃存用在需要很便宜的非易失數據存貯器的地方，一個大容量的閃存甚至被用作磁盤驅動器。

G

general-purpose computer（通用計算機）
A combination of computer hardware and software that serves as a
general-purpose computing platform. For example, a personal computer. Contrast with embedded system.
當作通用計算平臺的計算機硬件與軟件的組合。例如，PC。相對于嵌入式計算機。
    
H
HLL
See high-level language.
查閱高級語言。

Heap（堆）
An area of memory that is used for dynamic memory allocation. Calls to malloc and free and the C++ operators new and delete result in run-time manipulation of the heap.
一塊被用作動態(tài)內存分配的內存區(qū)域。調用malloc和free、C++的操作符new、delete在運行時進行堆的操作。

high-level language（高級語言）
A language, such as C or C++, that is processor-independent. When programming in a high-level language, it is possible to concentrate on algorithms and applications without worrying about the details of a particular processor. 
一種語言，象C或C++，是處理器獨立的。當在高級語言上編程時，不需要考慮特定處理器的細節(jié)，只用關心算法和應用。  <<容~源~電~子~網~版權聲明：本站內容部分來源于網絡，如侵犯到你的權利請及時與我們聯系更正，聯系QQ:316520686。
