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 debugging 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。
