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(xiàn)的軟件狀態(tài)，在這個狀態(tài)下，所有的任務(wù)因為等待一個只有在這些被阻塞任務(wù)之一才能產(chǎn)生的事件而被阻塞。如果死鎖發(fā)生，唯一解決的方法是重啟動硬件。但是，通過可靠的軟件設(shè)計實踐活動通常可以防止死鎖的發(fā)生。

debug monitor（除錯監(jiān)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(shè)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(wǎng)絡(luò)與除錯器進行通訊。除錯監(jiān)視程序提供一個簡單的命令集來顯示和內(nèi)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(jiān)視器組合這些簡單的命令去實現(xiàn)象程序下載各單步調(diào)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(fā)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(wǎng)絡(luò)連接到目標(biāo)機上。你能使用除錯器下載軟件到目標(biāo)機并直接運行。你也可以設(shè)置斷點并檢查特定內(nèi)存地址或寄存器的內(nèi)容。

device driver（設(shè)備驅(qū)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(shè)的細(xì)節(jié)并提供高級的外設(shè)編程接口。

device programmer（設(shè)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(fā)內(nèi)存和其他電可編程設(shè)備進行編程的工具。典型地，可編程設(shè)備被插到設(shè)備編程器的接口上，接著內(nèi)存緩存器中的內(nèi)容被傳送到它里面。

digital signal processor（數(shù)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(shè)備，不同的是它內(nèi)部的CPU被優(yōu)化，用于特定的應(yīng)用，如離散信號處理。除了標(biāo)準(zhǔn)的微處理器指令外，DSP常常支持復(fù)雜指令集去非常快地完成通用的信號處理計算。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(wǎng)~版權(quán)聲明：本站內(nèi)容部分來源于網(wǎng)絡(luò)，如侵犯到你的權(quán)利請及時與我們聯(lián)系更正，聯(lián)系QQ:316520686。
