So I began to write. At that time, my level was about: I could only do exercises in C language, and I only knew how to compile.Press F9, compile and know common instructions. In addition, you can do a little Win 32 programming, and you can use Windows fluently.
call cmain; call the main function mov ax written in C language, 4c00h; call the function of DOS (for debugging), which has nothing to do with our own operating system int 21h. This code is very simple and should be no problem.
For the sake of simplicity, use the simplest AT89S52 to run the program: the number of clear bytes with a small memory, and only a few IOs in the peripherals. The structure is simple, which is very convenient for the writing of the operating system.
C language is designed as a more sophisticated and simpler version than its predecessor. It is suitable for writing system-level programs, such as operating systems.Before that, the operating system was written in assembly language and could not be ported. C language is the first programming language that makes system-level code porting possible.
In March, when everyone said that the WeChat dividends were exhausted, the author created Li Zi Media Zhu Zuo has accumulated 400,000 fans in 1 year just by writing original articles. Based on 3 years of experience in writing explosive articles, he systematically summarizes the most operational writing skills, hoping to let more people learn to write and make money by writing.
Ge Yiming, 51CTO special lecturer, national certification system analyst, obtained OracleOCP certification.
The second part mainly talks about the editing of configuration files, which is used for command line control of computer operations. The third part describes the routine tasks performed from the command line. UNIX-like operating systems, such as Linux, contain many "classic" command-line programs that can efficiently manipulate data.
He is the principle designer of the Amsterdam compiler, which is a widely used toolbox for writing portable compilers. The MINIX he led to write is a small UNIX-like operating system for operating system teaching.
1. "A better student with a master's degree in computer science. Writing the kernel of an operating system is definitely something that should and can definitely be done." --- This sentence can be understood as "the theoretical knowledge of a good computer master is enough for him to build a simple operating system framework".
2. After completing Brans, I partially referred to how difficult it is to write an operating system kernel? What are the general content and steps? - Recommended in To Qianmo's answer: hurley25/hurlex-doc · GitHub document, completed some simple debugging functions and library functions, printk and memory allocation.
3. A loss of hardware foundation, surprising logical ability, assembly, C.
