IntervalZero - RTX Time Extension for Windows

IntervalZero (formerly Ardence and Venturcom) RTX is the only software solution architected as a high-performance extension to control Microsoft Windows. RTX is proven in thousands of demanding applications providing enhanced performance, control, scalability combined with unmatched dependability for: industrial automation; military/aerospace; test and measurement equipment; robotics; and many other industries while reducing system costs and speeding time to market.

Deterministic, hard real-time performance – plus the Windows user experience
Microsoft Windows offers a world-class interface and excellent development tools for embedded systems. However, for mission-critical threads that require hard real-time, deterministic responses – e.g. robots, vision systems, simulators, test and measurement systems – the Windows scheduler cannot deliver the necessary prioritization and control.

Replace dedicated DSP and FPGA hardware with a Windows PC
The untapped power of the latest Intel multicore processors is a match for demanding signal processing tasks, currently performed by expensive dedicated DSP or FPGA hardware, running incompatible and difficult-to-maintain firmware. RTX SMP allows users to harness the available power of up to 32 PC processor cores to take on the most demanding DSP tasks, in professional audio, video, medical imaging and simulation applications.

RTX2012 and RTX64
RTX is available in two versions, RTX2012 and new RTX64 which is a designed to take advantage of the 64-bit systems. RTX64 can access 128GB of non-paged memory, depending on actual mapped physical RAM size. Both versions of RTX can scale from 1 to 63 cores for dedicated real-time processing.

With IntervalZero’s RTX, developers can take advantage of both the Windows environment and form factor, and also solve all their scheduling, prioritization and control challenges. RTX is a self-contained real-time subsystem that bypasses the Windows’ scheduler to provide the desired determinism and hard real-time response.

RTX architecture is a true extension in that it does not encapsulate Windows and does not interfere with or modify the Windows infrastructure. By maintaining this separation, the RTX real-time subsystem (RTSS) ensures that RTX-based applications survive Windows crashes.

The RTX real-time subsystem is designed around a high-speed scheduler that utilizes both priority-driven and preemptive algorithms. RTX supports up to 997 independent processes, with each process supporting unlimited threads. Fine-grained control over applications is assured with 128 levels of assignable thread priority.

Industrial Automation
Some of the world’s most demanding high-speed control and automation applications are running on standard Windows PCs using IntervalZero’s Embedded software solutions.

Customers have eliminated their dedicated “real-time” PCs, DSPs and PLCs in favor of an RTX-enabled unified Windows-based control system.

Using RTX, companies such as Siemens, Honda, MDSI and Hurco are delivering high-performance control systems for Computerized Numerical Control, Motion-Control, Material Handling/Sortation and Discrete Control.

The benefits include:

  • Reduced material costs
  • Reduced development times
  • More flexible and customizable systems
  • Reduced field-support costs

RTX loads as a driver to Windows and takes over the Windows scheduler and interrupt service. RTX processes have 128 priority levels - all higher than Windows and microsecond response time.

RTX has real-time support for all of the popular communication protocols such as TCP/IP, Modbus TCP, ControlNet/DeviceNet, Profibus, ASI, Industrial Ethernet and others.

Digital Audio
By combining Microsoft Windows, x86 multicore and IntervalZero's symmetric-multiprocessing-enabled RTX software, Digital Media Systems OEMs and system owners take full advantage of the breakthrough capabilities of Soft-Control Architectures. Doing so enables them to achieve significant cost, productivity and quality improvements by replacing expensive, proprietary DSP/PowerPC/FPGA hardware with software components.
