Alpha Emulation, How does it work?
vtAlpha creates a virtual equivalent of the original Alpha system inside a modern general purpose computer (Intel or AMD processor based X86 architecture). Your Alpha software recognizes the system it used to run in and continues to operate unchanged.
No software changes ⇒ no problems.
It really is that simple. The process of course, not the technology behind it. By creating the exact equivalent of the Alpha you are replacing, your software is presented with the hardware interfaces it is used working with. Which means your software does not need to change.
