Deadlock（死鎖）
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.
一種不希望出現的軟件狀態，在這個狀態下，所有的任務因為等待一個只有在這些被阻塞任務之一才能產生的事件而被阻塞。如果死鎖發生，唯一解決的方法是重啟動硬件。但是，通過可靠的軟件設計實踐活動通�？梢苑乐顾梨i的發生。

debug monitor（除錯監視程序）
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.
嵌入式軟件被特殊設計來作為除錯工具的一部分。它一般被放在ROM中，通過串口或網絡與除錯器進行通訊。除錯監視程序提供一個簡單的命令集來顯示和內存地址和寄存器、建立和移除斷點，并且運行你的程序。除錯監視器組合這些簡單的命令去實現象程序下載各單步調試等高端的請求。

Debugger（除錯器）
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.
一個軟件開發工具，被用來對嵌入式軟件進行測試和除錯。除錯器在宿主機上運行并且通過串口或網絡連接到目標機上。你能使用除錯器下載軟件到目標機并直接運行。你也可以設置斷點并檢查特定內存地址或寄存器的內容。

device driver（設備驅動程序）
A software module that hides the details of a particular peripheral and provides a high-level programming interface to it. 
  一個軟件模塊，它隱藏特定外設的細節并提供高級的外設編程接口。

device programmer（設備編程器）
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.
一種用來對不揮發內存和其他電可編程設備進行編程的工具。典型地，可編程設備被插到設備編程器的接口上，接著內存緩存器中的內容被傳送到它里面。

digital signal processor（數字信號處理器）
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.
   一種類似于微處理器的的設備，不同的是它內部的CPU被優化，用于特定的應用，如離散信號處理。除了標準的微處理器指令外，DSP常常支持復雜指令集去非�？斓赝瓿赏ㄓ玫男盘柼幚碛嬎�。通用DSP家庭是TI的320Cxx和Motorola的5600x系列。

E

EEPROM（電可擦的，可編程的只讀存儲器）
Electrically Erasable, Programmable Read-Only Memory. (Pronounced"Double-E"-PROM.) A type of ROM that can be erased electronically.
電可擦的，可編程的只讀存儲器。一種ROM能被電擦除。 <<容~源~電~子~網~版權聲明：本站內容部分來源于網絡，如侵犯到你的權利請及時與我們聯系更正，聯系QQ:316520686。
