Project Summary
COSMOS (C# Open Source Managed Operating System)
Cosmos includes a compiler (IL2CPU, which is part of Cosmos) that reads the input file (usually the shell) and Cosmos libraries and compiles the resulting IL to x86 code. IL2CPU has a layer for cross platform and we plan to support other processors and platforms, including x64. IL2CPU also supports certain extension methods which allow C# code to interact directly with the CPU, registers, and ports in the kernel. IL2CPU contains some inline assembler, but there are no ASM files that need to be linked in.
Currently IL2CPU first outputs raw asm files (with IL comments) and then processes them through nasm (a free assembler). Later we plan to emit directly to binary.
In a Nutshell, Cosmos (C# Open Source Managed Operat...
