Execution Code by using real CPU! no Emulation!!

Hi every body,

I know there are many CPU emulator free and open source around the web. But I like to execute code by real CPU for its speed. I think I can run code by making a new thread inside my program. Problem is program can not work with making a memory access virtualization and Stack memory virtualization. In on sentence, what should I do for emulation access to memory? How can I detect when Instruction Pointer come to access to memory? Some one said to me I muss play with exception. Is it true? If yes, how can I do?

Vodu,
