电子术语中英文对照

去写（读）某一特定外设中的存储器地址或寄存器中的内容时，处理器设置地址总线并在数据总线上接收（传输）内容。

　　Deadline（死线）

The time at which a particular set of computations must be completed. See also real-time system.

一个特定计算必须被完成的时间。请看实时系统。

　　Deadlock（死锁）

　　 An unwanted software situation in which an entire set of tasks is blocked, waiting for an event that only a task within the same set can cause. If a deadlock occurs, the only solution is to reset the hardware. However, it is usually possible to prevent deadlocks altogether by following certain software design practices.

一种不希望出现的软件状态，在这个状态下，所有的任务因为等待一个只有在这些被阻塞任务之一才能产生的事件而被阻塞。如果死锁发生，唯一解决的方法是重启动硬件。但是，通过可靠的软件设计实践活动通常可以防止死锁的发生。

　　debug monitor（除错监视程序）

　　 A piece of embedded software that has been designed specifically for use as a debugging tool. It usually resides in ROM and communicates with a debugger via a serial port or network connection. The debug monitor provides a set of primitive commands to view and modify memory locations and registers, create and remove breakpoints, and execute your program. The debugger combines these primitives to fulfill higher-level requests like program download and single-step.

嵌入式软件被特殊设计来作为除错工具的一部分。它一般被放在ROM中，通过串口或网络与除错器进行通讯。除错监视程序提供一个简单的命令集来显示和内存地址和寄存器、建立和移除断点，并且运行你的程序。除错监视器组合这些简单的命令去实现象程序下载各单步调试等高端的请求。

　　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
