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(gè)狀態(tài)下,所有的任務(wù)因?yàn)榈却粋(gè)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(dòng)硬件。但是,通過可靠的軟件設(shè)計(jì)實(shí)踐活動(dòng)通常可以防止死鎖的發(fā)生。
debug monitor(除錯(cuò)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(jì)來作為除錯(cuò)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(cuò)器進(jìn)行通訊。除錯(cuò)監(jiān)視程序提供一個(gè)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(diǎn),并且運(yùn)行你的程序。除錯(cuò)監(jiān)視器組合這些簡單的命令去實(shí)現(xiàn)象程序下載各單步調(diào)試等高端的請(qǐng)求。
Debugger(除錯(cuò)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(gè)軟件開發(fā)工具,被用來對(duì)嵌入式軟件進(jìn)行測(cè)試和除錯(cuò)。除錯(cuò)器在宿主機(jī)上運(yùn)行并且通過串口或網(wǎng)絡(luò)連接到目標(biāo)機(jī)上。你能使用除錯(cuò)器下載軟件到目標(biāo)機(jī)并直接運(yùn)行。你也可以設(shè)置斷點(diǎn)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(dòng)程序)
A software module that hides the details of a particular peripheral and provides a high-level programming interface to it.
一個(gè)軟件模塊,它隱藏特定外設(shè)的細(xì)節(jié)并提供高級(jí)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(duì)不揮發(fā)內(nèi)存和其他電可編程設(shè)備進(jìn)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(hào)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(hào)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(hào)處理計(jì)算。通用DSP家庭是TI的320Cxx和Motorola的5600x系列。

EEPROM(電可擦的,可編程的只讀存儲(chǔ)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(chǔ)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(qǐng)及時(shí)與我們聯(lián)系更正,聯(lián)系QQ:316520686。
