OSDev Series: IA32 machine language

Post by Mike » Mon Dec 19, 2011 7:46 pm

Hello everyone,

This is the initial release for the OSDev Series advanced chapter covering IA32 and IA64 machine language. It provides an introduction to machine language topics, instruction encoding, using instruction look-up tables, and some examples of translating instructions.

We are transitioning to a different writing environment for the series to present a standard formatting method and resolve spelling errors that are present in earlier chapters.

Hey,

Sorry to call you out on this, but IA64 is the Intel Itanium architecture, not 64bit x86 archtecture.

The naming is very confusing.

32bit:
x86 (most common name)
IA-32 (Intel name - default in their manuals)
i386 (Linux 32bit stuff, including systems code)
i686 (Linux 32bit kernel level stuff)

64bit:
AMD64 (AMD name - they invented it licenced it to Intel)
Intel64 (Old Intel name - still exists in older documents)
EMT64 (Extended Memory Technology 64bit) (New Intel name, following confusion with IA64 name)
IA-32e (Intel Architecture extensions) (Another Intel name, common in their manuals)
x86_64 (Common in most open source systems code - Xen, Linux etc.)

Itanium:
IA64 (Itanium Architecture)

A cynic might draw a comparason about some of the naming conventions and some of the silly obscure legacy components of x86.

Hello,

No worries, you are correct. I have been notified a few weeks ago on the potential confusion the name could cause. It will be fixed :)
