I now is such a thought

Under the Windows used to write a simple 1 + 1=2 computer, compiled to run, if I think he is too slow, don't want to rely on the win to write good assembly language to run,
Also heard that Intel sse instructions for calculation is very good, especially the floating point arithmetic, and then I created a [assembly language and machine language and CPU instruction set (such as sse series) and the relationship between the compilation], I don't know how to put without win assembly compiler assembler compiled into without an operating system to run, it is compiled into the binary machine code, then don't know if assembly can directly call sse instruction execution floating point calculations and achieve without Windows or MAC or Linux to run,
Problems: unclear: : : assembly language and machine language and CPU instruction set (such as sse series) and the relationship between the compilation
