何时使用16位汇编 [英] when to use 16-bit assembly
问题描述
我想开发的是一个32位操作系统。
所以我开始使用NASM x86 32位编程。
但是在开发操作系统时我需要16位汇编程序。
你能建议吗？

这是一项艰巨的任务！
引用：所以我已经开始使用NASM x86 32位编程。
我本来会先学习一些关于操作系统的书。
引用：但是什么时候我需要16位汇编程序来开发操作系统。
我不会打扰。

这个问题与手头的任务相比无关紧要.BTW：为什么要在汇编中编写操作系统？这是在上世纪七十年代放弃的，即。 C是为了重新编写UNIX而发明的，因为没有它，工作结果就不会缩放...
几乎所有你能通过汇编程序实现的东西都可以通过体面的C来实现交叉编译器 - 一些罕见的例外情况适用。
C可以实现的一切都可以通过降级C ++交叉编译器来实现 - 可能没有例外。 ;-)
是否有一些我写自己的操作系统发烧突破？例如。另见重新发送类似请求 [ ^ ]。 ;-)
OS的期望可能会有所不同。

Hi,
All I would like to develop is a 32 bit operating system.
So I have started with NASM x86 32-bit programming.
But when is it that i require 16-bit assembly programs while developing an operating system.
Could you please suggest?

That''s a daunting task!
Quote:So I have started with NASM x86 32-bit programming.
I would have first studied some books about operative systems.

I wouldn''t bother about.

You might start reading this article series: Beginning Operating System Development"[^]
Have a look at Booting[^]

This question is so irrelevant compared to the task at hand. BTW: why would you write an OS in assembly? This was given up in the senventies of the last century, I.e. C was invented to re-write UNIX since without it the work results would not have scaled...
Almost everything you can achieve by assembler can be achieved by decent C cross-compiler - some rare exceptions apply.
Everything you can achieve by C can be achieved by a decend C++ cross-compiler - probably no exceptions apply. ;-)
Is there some I-write-my-own-OS fever breakout? E.g. see also a resent similar request[^]. ;-)
Expectations on "OS" may vary, though.
