Debugger（除错器）

 A software development tool used to test and debug embedded software. The debugger runs on a host computer and connects to the target through a serial port or network connection. Using a debugger you can download software to the target for immediate execution. You can also set breakpoints and examine the contents of specific memory locations and registers. 一个软件开发工具，被用来对嵌入式软件进行测试和除错。除错器在宿主机上运行并且通过串口或网络连接到目标机上。你能使用除错器下载软件到目标机并直接运行。你也可以设置断点并检查特定内存地址或寄存器的内容。

 

 device driver（设备驱动程序）

 A software module that hides the details of a particular peripheral and provides a high-level programming interface to it. 一个软件模块，它隐藏特定外设的细节并提供高级的外设编程接口。

 

 device programmer（设备编程器）

 A tool for programming non-volatile memories and other electrically-programmable devices. Typically, the programmable device is inserted into a socket on the device programmer and the contents of a memory buffer are then transferred into it. 一种用来对不挥发内存和其他电可编程设备进行编程的工具。典型地，可编程设备被插到设备编程器的接口上，接着内存缓存器中的内容被传送到它里面。

 

 digital signal processor（数字信号处理器）

 A device that is similar to a microprocessor, except that the internal CPU has been optimized for use in applications involving discrete-time signal processing. In addition to standard microprocessor instructions, DSPs usually support a set of complex instructions to perform common signal-processing computations quickly.Common DSP families are TI"s 320Cxx and Motorola"s 5600x series. 一种类似于微处理器的的设备，不同的是它内部的CPU被优化，用于特定的应用，如离散信号处理。除了标准的微处理器指令外，DSP常常支持复杂指令集去非常快地完成通用的信号处理计算。通用DSP家庭是TI的320Cxx和Motorola的5600x系列。

 

 E 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 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。
