电子术语中英文对照

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 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.

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 place of 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 most 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. 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. Contrast 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 malloc and free and the C++ operators new and delete result in run-time manipulation 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 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 port or network connection. This term is usually used to distinguish the computer on which the debugger is running from the embedded system that is being developed.

一台通用计算机
