Kithara »RealTime USB«

Real-time communication with USB devices under Windows®

The »RealTime USB« is a modular real-time extension for the Windows® range of operating systems with a special focus on USB 3.0 in real-time by direct access to XHCI.

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!

Some features:

  • Highly-accurate real-time timer for frequencies > 20 kHz
  • Priority-based preemptive real-time multi-tasking
  • Code execution on the kernel-level supported by C/C++ and Delphi (native code generation necessary)
  • Supports Windows 7/8/10 with 32 or 64 bit! - request your non-binding upgrade offer now!
  • Protection with sticker, online-activation or USB-dongle

The product »RealTime USB« consists currently of more than 20 different modules. The software can be combined of these modules according to customer requirements. Few dependencies exist.

Customer-specific Software Combination

Combine your function set by yourself using the real-time configurator or ask us for help. The custom specific driver gives you highest flexibility and has the following features:

  • The software can be combined arbitrarily with modules, few dependencies exist
  • The name of development and runtime files is arbitrary
  • Simplified installation (no registry entry)
  • Regarding new versions, no modification is necessary
  • With the purchase of the modules you will automatically receive a developer's license
  • Favourable price scale conditions for runtime licenses
  • Always state of the art software due to quarterly updates on CD (12 months)
  • Expandable at any time by additional modules
  • 4 different support packages (1, 3, 6 or 12 months) for developer support (consulting, concept development, analysis)

Our qualified Support-Team guarantees you the best possible service for integrating the software into your project and our development support assists you also in questions beyond the software!

Platforms

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.

System Requirements

The products of the »RealTime Suite« support a wide range of hardware and software combinations:

If you have questions regarding the system support, please contact us!

Operating system

The software supports the following operating systems:

  • Windows 10 (32 and 64 bit, 64 bit only by using the dedicated mode)
  • Windows 8 and 8.1 (32 and 64 bit, 64 bit only by using the dedicated mode)
  • Windows Server 2012 (64 Bit, only using by the dedicated mode)
  • Windows 7 (32 and 64 bit) + Windows Embedded Standard 7
  • Windows Server 2008 R2 (64 bit)

Hardware

The software runs on the following hardware:

  • CPU: AMD (Athlon) or Intel (Pentium 2), 32 - or 64-bit
  • Single-or multi-core, Hyperthreading, plain version to 8 logical CPU cores (extended version currently up to 32 logical cores, more details on request)
  • ACPI recommended (Advanced Control and Power Interface), APIC recommended (Advanced Programmable Interrupt Controller) - Some features require ACPI-APIC
  • the PC must be able to support PAE (Page Address Extension)
  • Using Gigabit-Ethernet, controller of Intel and RealTek are generally supported on demand

Compiler

Immediately usable program frameworks for the following programming languages / compilers are included in the supplied software (other programming languages can be supported on request):

  • Visual Studio 20xx C++ with MFC user interface (supplied project files: VS 2005/08/10/12/13/15)
  • C++ Builder (Embarcadero, formerly Borland) VCL user interface
  • Delphi (Embarcadero, formerly Borland) VCL user interface
