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。
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。
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。
