<p>This is one of the most important pieces of code in Cosmos. It's an AOT (Ahead-Of-Time) compiler.</p>
<p>When you compile your C# (or any .NET language) program, it is compiled into CIL (common intermediate language). The CIL is then interpreted and executed by a virtual machine when you open your exe.</p>
<p>Cosmos is written in C# and Visual Studio compiles it into CIL as always. But a PC does not come with an interpreter for the CIL code. And writing a virtual machine for running an operating system is not always ideal.</p>
<p>This is where IL2CPU comes in. IL2CPU takes the CIL code and translates it to processor opcodes. Currently, only x86 opcodes are available at the moment. However, more architectures are planned for the future (ARM, PowerPC, x86-64).</p>

<h2 id="introducing-cosmos">Introducing Cosmos</h2>
<p>Cosmos (C# Open Source Managed Operating System) is an operating system
development kit which uses Visual Studio as its development environment.
Despite C# in the name any .NET based language can be used including VB.NET,
Despite C# in the name, any .NET based language can be used, including VB.NET,
Fortran, Delphi Prism, IronPython, F# and more. Cosmos itself and the kernel
routines are primarily written in C#, and thus the Cosmos name. Besides that,
NOSMOS (.NET Open Source Managed Operating System) sounds stupid.</p>
<p>Cosmos is not an operating system in the traditional sense, but instead it is
an &quot;Operating System Kit&quot;, or as I like to say &quot;Operating System Legos&quot;.
Cosmos lets you create operating systems just as Visual Studio and C# normally
let you create applications. Most users can write and boot their own operating
system in just a few minutes, all using Visual Studio. You can debug your operating system directly from Visual
Studio using breakpoints.</p>
<p>Cosmos is available in two distributions, the developer kit (dev kit), and the user kit. The dev kit is designed for users who want to work on Cosmos itself.
The user kit is designed for those who are interested in building their own
operating system and doing some Cosmos work. The dev kit might be thought of
as the Cosmos SDK. Most users should start off with the user kit as it is not
so overwhelming like the dev kit. This article focuses on the user kit.</p>
NOSMOS (.NET Open Source Managed Operating System) sounds silly.</p>
<p>Cosmos diverts from traditional operating systems because it is not an operating system in the conventional sense; rather, it is an &quot;Operating System Kit,&quot; similar to &quot;Operating System Legos&quot;. With Cosmos, you have the flexibility to construct operating systems just as how Visual Studio and C# help you develop applications. Using Visual Studio, most users can swiftly write and boot their own operating system within minutes. Additionally, debugging your operating system directly from Visual Studio is a feature, allowing for efficient troubleshooting through breakpoints.</p>
<p>Cosmos is available in two distributions, the developer kit (abbr. <em>DevKit</em>), and the user kit.
The DevKit was originally designed for those who want to work on Cosmos's core features, but now has superceded the inferior user kit due to having much more technical ability.
The User Kit was designed for those who are interested in building their own operating system and doing some Cosmos work. Since the User Kit is so heavily outdated, it is often recommended to download the DevKit when installing. The documentation will cover both.</p>
