连接处理器与所有外设进行通讯的电子线路集。当一个处理器想去写(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 al
so 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, w
aiting for an event that only a task within the same set can cause. If a dea
dlock occurs, the only solution is to reset the hardware. However, it is usu
ally 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 o
f primitive commands to view and modify memory locations and registers, crea
te and remove breakpoints, and execute your program. The debugger combines t
hese primitives to fulfill higher-level requests like program download and s
ingle-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 de
bugger runs on a host computer and connects to the target through a serial p
ort or network connection. Using a debugger you can download software to the
target for immediate execution. You can also set breakpoints and examine th
e 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 prov
ides 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-program
