EEPROM（电可擦的，可编程的只读存储器）
Electrically Erasable, Programmable Read-Only Memory. (Pronounced"Double-E"-
PROM.) A type of ROM that can be erased electronically.
电可擦的，可编程的只读存储器。一种ROM能被电擦除。
EPROM（可擦的，可编程的只读存储器）
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.
一种可用紫外线擦除的存储器。一次擦除后，EPROM可以在设备编程器的帮助下被重编程
。
embedded system（嵌入式系统）
A combination of computer hardware and software, and perhaps additional mech
anical or other parts, designed to perform a dedicated function. In some cas
es, 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 compu
ter.
计算机硬件和软件的结合体，或许还加上机械等其他部分，被设计来完成专门的功能
。在一些情况下，嵌入式系统是一个大的系统或产品的一部分，就象汽车上的防抱死装
置。与通用计算机相对。
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 incorpora
te a special "bond-out" version of the target processor that allows you to
observe and record its internal state as your program is executing
. 在线仿真器的简写。一个在你的目标板上放置仿真的处理器的调试工具。仿真器经常
和一目标处理器的一种“外合”版本合在一起，这个版本的的处理器充许你运行程序时
观察和记录它的内部状态。
Executable（可执行的）
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 de
bugging tool.
一个包含准备在目标机上运行的目标代码的文件。放置目标代码到ROM中或通过调试
工具下载。
F
Firmware（固件）
Embedded software that is stored as object code within a ROM. This name is m
ost common among the users of digital signal processors.
是作为目标代码存贮在ROM中的嵌入式软件。这个名字在数字信号处理器的用户中相当流
行。
flash memory （闪存）
A RAM-ROM hybrid that can be erased and rewritten under software control. Su
ch devices are divided into blocks, called sectors, that are individually-er
asable. Flash memory is common in systems that require nonvolatile data stor
age at very low cost. In some cases, a large fash memory may even be used in
stead of a disk-drive.
一种RAM-ROM的混血儿，它能在软件的控制下被擦除和重写。一些设备被分成叫段组
的块，能个别地可擦。闪存用在需要很便宜的非易失数据存贮器的地方，一个大容量的
闪存甚至被用作磁盘驱动器。
G
general-purpose computer（通用计算机）
A combination of computer hardware and software that serves as a
general-purpose computing platform. For example, a personal computer. Contra
st with embedded system.
当作通用计算平台的计算机硬件与软件的组合。例如，PC。相对于嵌入式计算机。
H
HLL
See high-level language.
查阅高级语言。
Heap（堆）
An area of memory that is used for dynamic memory allocation. Calls to mallo
c and free and the C++ operators new and delete result in run-time manipulat
ion of the heap.
一块被用作动态内存分配的内存区域。调用malloc和free、C++的操作符new、delete在
运行时进行堆的操作。
high-level language（高级语言）
A language, such as C or C++, that is processor-independent. When programmin
g in a high-level language, it is possible to concentrate on algorithms and
applications without worrying about the details of a particular processor.
一种语言，象C或C++，是处理器独立的。当在高级语言上编程时，不需要考虑特定处理
器的细节，只用关心算法和应用。
Host（主机）
A general-purpose computer that communicates with the target via a serial po
rt or network connection. This term is usually used to distinguish the compu
ter on which the debugger is running from the embedded system that is being
developed.
一台通用计算机，它通过串口或网络连接与目标机通讯。这处名词一般用来区别调试程
序运行的计算机和被开发的嵌入式系统。
