Tiny-OS project introduction^^

About this Tiny-OS This is a project I wrote from scratch with "Operating System Truth Restore" of course, the code in it is now the last version of the code. Except for the last three functions in this book, Exec Wait Exit and pipelines, the rest are all implemented. All implementations are recorded in the blog. CSDN: (https://love6.blog.csdn.net)
It records my implementation process in detail in each chapter and also erratizes the errors in this book.

It's not easy to implement this project. It took me about 40 days to do it.

From morning to night, I kept reading and typing code to finally come true

Debug and debugging are common for a few days. Of course, it is still very happy.

Although most of the code is the code in the book, it is exciting to be able to understand most of the code and type it again and achieve it correctly.

These codes are now open source and hope they will be helpful to all those who are interested in learning the operating system haha

I just counted the number of lines of code, including the number of lines of MakeFile and header files, it is about 7800 lines. If you throw away those lines of only core code, it is about 6000 lines, haha, I didn't expect that it would be difficult for me to persist in writing so many lines.

Then ReadMe wrote this first, but I didn’t expect that it also uses MarkDown’s syntax as the first project uploaded on GitHub. I’m quite happy. Goodbye to everyone!

Hope u can enjoy this tiny os~ Sharing and Getting.
