. This base address plus your offset two a plus to generate the final physical address is equivalent to saying that you pass the physical bus The address at which this memory was accessed
Protection mode protects what.
is to distinguish between the stores used by different tasks, and not allow the data and code of other tasks to be used casually.
That's the equivalent of taking the GDT to locate the LDT through the GDT and then through this LDT to locate your section base with this section
The evolution of computer language originates from machine languageMachine language(1) is a collection of machine instructions. Machine instructions are binary information consisting of 0 and 1.(2) Directly facing the machine, and the machine's hardware operation one by one corresponds. Computers can be directly identified, executed, using machine language can gi
EmbeddedLinux arm Compilation (vii)--C language and arm Assembly mixed programming in the development of embedded system, the main programming language currently used is C and assembly. In large-scale embedded software, such as the OS, most of the code is written in C, mainly because C
In school, most of the students may be the language of the introduction of the C language, but often more or less will learn the assembly language. However, at that time, we felt that the compilation was really too difficult, and the meaning seems to be small.And now, after work, find some truth, the more basic, the mo

I saw a question in the Forum a few days ago. I have a reply below.
[Quote = reference reply on the 21st floor:]The C ++ language can indeed create various wonders. I don't know whether it is its glory or sorrow.[/Quote]
His reply does not help the landlord's problem because it is not a language problem.So when I saw his complaint, I wanted to refute him, but then I only helped the landlord solve the proble
Arm compilers generally support assembly language programming, C/C ++ programming, and mixed programming. This chapter introduces some basic concepts of arm program design, such as pseudo commands of arm assembly language, statement format of assembly
Java-implemented Hack language assembly compiler-the sub-device part
I recently read computer system elements and read some basic things. I found that it would be nice to read this book before the university course compilation. Although some of it is difficult, it is still possible to browse it. After reading this article, you will know how to use this compilation item. The same is true for model-based elec
(corrected) This problem includes the hardware structure of the CPU and the category of assembly language. Here, comb it.First of all, the main "Li Jianguo" self-answer part of the question is said to be correct,the instruction set of the CPU is the interface between the two tiers of software and CPU, and the CPU itself is the "instantiation" of this set of CPU instructions..No matter how advanced the softw
Chapter I.Assembler linker: Assembler translates assembly language into machine languages, linker merges individual files into executable filesIs the assembly language of the Intel 80x86 series processor the same as that of a VAX or Motorala 68x00 system?Not the same, assembly
For beginners, the compilation of many commands is too complex, often learning for a long time can not write a beautiful program, so as to hinder our interest in learning compilation, many people give up. Therefore, I personally read the legal compilation, but I don't have to write a program. Writing a program is really not a compilation strength. You may wish to play debug, sometimes crack has a more sense of accomplishment than a program (just like learning to play games first on a computer ).

Some advanced commands are actually only useful to experienced assembler programmers. They are too advanced for us. To make learning assembly
"Oh, man, what's the compilation?" It's useless, brother. Use VB "Fishing" an API is enough for you to work a 10-day and a half month, still not necessarily get out. "This gentleman's speech is not empty, then we still have no need to grind him to investigate?" (Nonsense, of course!) Why else would you write this article? Don't worry, don't worry, let me take the whole story slowly: one, all computer language written program in memory are stored in th

Specific examples of C language analysisAt first glance, This approach seems a bit confusing, so let's start with a simple C language example:On the IA-32 system, The assembly code itself must be given by The-t Notation.It is sufficient to summarize the follo

In the development process of embedded software systems, a large number of applications are developed using C language to improve development efficiency. At the same time, the system often contains some key modules that determine the overall system performance. In order to achieve the best performance, they are often written in assembly language, or in some speci
The main description of the three aspects of the content: the first is the assembly language program template, and the template involved in some of the knowledge points; the second is how to debug assembly language, and the third is how to call C library function in assembly
before learning the assembly language, although as a computer professional students, but the basic computer knowledge can only be said to be small white, for computer cognition is still very lack of understanding. understanding of the production and development of assembly language, I feel that
The recommended star rating for this book is: 5 stars. After all, it is a classic book, Nothing to say.As far as the Assembly itself is concerned, the preparation of high-efficiency programs and the optimization, commissioning, and reverse engineering of the project is a foundation; in terms of the theoretical operating system, the assembly lets you understand the CPU, understand the architecture of the com
