Kithara »RealTime Suite«

Windows® Real-time Extension for PC-based Automation

The »RealTime Suite« is a modular real-time extension for the Windows® range of operating systems. Using it, you can easily implement industrial applications for automation and control solutions as well as image processing in real-time.

Almost all mechanisms can be used from real-time as well as application context. Developers can decide depending on the use-case, if they wish to access hardware directly out of the application program or if “hard real-time” is required.

In order to gain “hard” real-time capabilities, it is necessary to run the application code in the kernel-mode of the system. This is provided by the software.

The required programming languages must be able to generate native x86 or x64 machine code, e.g. C/C++ or Delphi. The hardware-dependent and time-critical code should be transferred to a DLL, which will be loaded directly into the real-time context. This way the .NET environment will also be supported, so that even C# can be used as the programming language for the main parts of the application.

Create 32-bit as well as 64-bit applications from a single unique code-base! Both worlds are absolutely source-code compatible – with a special module ("KiK64") even binary compatible!

Real-time capability can only be achieved on the kernel level.

For this purpose a programming language is required that is able to generate native x86 or x64 machine code, e.g. C/C++ or Delphi. Nevertheless the »RealTime Suite« supports various platforms, for example a .NET environment.

The solution is, to transfer the time-critical code into a DLL, which will be loaded directly into the real-time context at the kernel level. The »RealTime Suite« provides all this functions.

Instantly usable program frameworks for the platforms mentioned above are part of every software delivery.
