EPROM(可擦的,可編程的只讀存儲器) 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. 一種可用紫外線(xiàn)擦除的存儲器。一次擦除后,EPROM可以在設備編程器的幫助下被重編程。
embedded system(嵌入式系統) 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. 計算機硬件和軟件的結合體,或許還加上機械等其他部分,被設計來(lái)完成專(zhuān)門(mén)的功能。在一些情況下,嵌入式系統是一個(gè)大的系統或產(chǎn)品的一部分,就象汽車(chē)上的防抱死裝置。與通用計算機相對。
Emulator(仿真器) Short for In-Circuit Emulator (ICE). A debugging tool that takes the placeof-emulates-the processor on your target board. Emulators frequently incorporate a special "bond-out" version of the target processor that allows you to observe and record its internal state as your program is executing . 在線(xiàn)仿真器的簡(jiǎn)寫(xiě)。一個(gè)在你的目標板上放置仿真的處理器的調試工具。仿真器經(jīng)常和一目標處理器的一種“外合”版本合在一起,這個(gè)版本的的處理器充許你運行程序時(shí)觀(guān)察和記錄它的內部狀態(tài)。
Executable(可執行的) A file containing object code that is ready for execution on the target. All that remains is to place the object code into a ROM or download it via a debugging tool. 一個(gè)包含準備在目標機上運行的目標代碼的文件。放置目標代碼到ROM中或通過(guò)調試工具下載。
F Firmware(固件) Embedded software that is stored as object code within a ROM. This name is most common among the users of digital signal processors. 是作為目標代碼存貯在ROM中的嵌入式軟件。這個(gè)名字在數字信號處理器的用戶(hù)中相當流行。
flash memory (閃存) A RAM-ROM hybrid that can be erased and rewritten under software control. Such devices are divided into blocks, called sectors, that are individually-erasable. Flash memory is common in systems that require nonvolatile data storage at very low cost. In some cases, a large fash memory may even be used instead of a disk-drive. 一種RAM-ROM的混血兒,它能在軟件的控制下被擦除和重寫(xiě)。一些設備被分成叫段組的塊,能個(gè)別地可擦。閃存用在需要很便宜的非易失數據存貯器的地方,一個(gè)大容量的閃存甚至被用作磁盤(pán)驅動(dòng)器。
G
general-purpose computer(通用計算機) A combination of computer hardware and software that serves as a general-purpose computing platform. For example, a personal computer. Contrast with embedded system. 當作通用計算平臺的計算機硬件與軟件的組合。例如,PC。相對于嵌入式計算機。
H HLL See high-level language. 查閱高級語(yǔ)言。
Heap(堆) An area of memory that is used for dynamic memory allocation. Calls to malloc and free and the C++ operators new and delete result in run-time manipulation of the heap. 一塊被用作動(dòng)態(tài)內存分配的內存區域。調用malloc和free、C++的操作符new、delete在運行時(shí)進(jìn)行堆的操作。
high-level language(高級語(yǔ)言) A language, such as C or C++, that is processor-independent. When programming in a high-level language, it is possible to concentrate on algorithms and applications without worrying about the details of a particular processor. 一種語(yǔ)言,象C或C++,是處理器獨立的。當在高級語(yǔ)言上編程時(shí),不需要考慮特定處理器的細節,只用關(guān)心算法和應用。 <<容~源~電~子~網(wǎng)~版權聲明:本站內容部分來(lái)源于網(wǎng)絡(luò ),如侵犯到你的權利請及時(shí)與我們聯(lián)系更正,聯(lián)系QQ:316520686。
