Can I use my 32 bit real-time application on a 64 bit system?

We distinguish 3 different ways to get real-time on a Windows-PC:

  1. 32 bit applications on a 32 bit Windows
  2. (like  1 and additionally) 64 bit application on a 64 bit Windows
  3. (like  2 and additionally) 32 bit applications on a 64 bit Windows

One version of our software only supports 32 bit applications on a 32 bit Windows. An extended version also supports to run 64 bit application on a 64 bit Windows.

If 32 bit applications should run on a 64 bit Windows, then the so called “KiK64” (Kithara32-in-Kithara64) is required. This is a special extension to support executing 32-bit code within the 64-bit real-time context. Thus, the KiK64 enables by only one 32-bit application all Windows systems (32 and 64 bit).

For comprehensive and challenging projects it should be noted though, that often a conversion between 32 and 64 bit addresses (code and data) takes place. For a better run-time behaviour it is strongly recommend running rather native 64-bit applications on a 64-bit system.
