摘要 为对计算机系统有更好的理解和认识,本文对简单的hello程序从代码到运行再到最后终止过程的底层实现进行了分析,描述了与之相关的计算机组成与操作系统的相关内容。基于Linux平台,通过gcc、objdump、gdb、edb等工具对一段程序代码预处理、编译、汇编、链接与反汇编的过程进行分析与比较,并且通过shell及其他Linux内置程...
From Program to ProcessRead the full-text online article and more details about "From Program to Process" by Peak, Martha H. - Personnel, Vol. 68, Issue 6, June 1991By PeakMartha H
The array of strings passed to main is to receive command line arguments. The JVM generally takes the following steps in order to run a Java program. Loading of Classes and InterfacesLoading refers to the process of finding the binary form of a class or interface type with a particular name...
It creates a pipe between the calling program and the executed command, and returns a pointer to a stream that can be used to either read from or write to the pipe. The environment of the executed command will be as if a child process were created within the popen() call using fork()...
7、Build Process 我们再来复习一下程序是如何运行起来的。其可以简单概括为CALL,即Compile,Assembler,Link,Load。(这一部分主要就是把老师的课件放上来,可以不用看我写的文字) 预处理可以算作Compile的一部分,其主要作用是展开宏定义,头文件。 然后编译操作将高级语言转换为汇编语言,这里的汇编语言还包含一些伪代码...
and conditional tests on the data in its registers,sending the resulting data back to RAM or storing it in another register for further use.During this process,a unit called the program counter keeps track of each successive instruction to make sure that the program instructions are followed by...

A process is a series of steps taken to achieve something, such as the process of making cake. Gather ingredients Mix ingredients Bake Decorate cake Processing is when you do things to a substance in order to change it. For example: the processing of oil into gasoline.process的意思是“步骤...
p49, The data items a function is given to process are called it's parameters。 给予函数处理的数据项称为函数的参数。 (3)interface p49, The parameter list and the processing expectations of a function(what it is expected to to with the parameters) are called the function's interface。
《programming from the ground up》:p96, In this, everything is character data except for the age, which is simply a numeric field, using a standard 4-byte word(we could just use a single byte for this, but keeping it at word makes it easier to process)。
