与之一样有相同功能的命令是“display/i $pc” ,当运行完这个命令后,单步跟踪会在打出程序代码的同时打出机器指令(也就是汇编代码) 2)信号(Signals) 信号是一种软中断,是一种处理异步事件的方法。一般来说,操作系统都支持许多信号。尤其是UNIX,比较重要应用程序一般都会处理信号。UNIX定义了许多信号,比如SIGINT表...
Signals: Description:Signals are software interrupts delivered to a process by the operating system. Signals can also be issued by the operating system based on system or error conditions. There is a default behavior for some (i.e. a process is terminated when it receives an inturrupt SIGINT ...

我经常想知道为什么VHDL variable既可以在process级别上声明,也可以在architecture (as shared)级别上声明,而signal只能在architecture级别上声明--即使它只是在单个process的范围内使用。在尽可能窄的范围内声明事物(例如signals或variables),并尽可能靠近使用它们的位置,在我看来,这确实增加了相当大的可读性。std_logic_v...
Motivated by the recent attention on superluminal phenomena, we investigate the compatibility between faster-than-c propagation and the fundamental principles of relativity and causality. We first argue that special relativity can easily accommodate—indeed, does not exclude—faster-than-c signaling at th...

handling is restored to default behaviour before handler is called. If handler returns, execution resumes where signal occurred. signal returns the previous handler or SIG_ERR on error. Initial state is implementation-defined. Implementations may may define signals additional to those listed...
