Real-Time under Windows

The SHA realtime extension for Windows (32-bit and 64-bit) leaves little to be desired. The ability of using individual processors as PLC system in realtime - fully decoupled from Windows - leads to a new dimension. Especially the highly accurate jitter performance (<10 microseconds) allows the realization of deterministic controller and automation applications. Each processor can be operated in realtime task-cluster as a single shot or periodic mode, with a frequency up to 200 KHz. The realtime extension, based on the asynchronous X-Realtime technology forms the base of all further libraries and enables the development of applications, e.g. for the control of hardware resources in realtime. The X-Realtime engine works without any additional hardware under Windows (32-bit and 64-bit) and allows realtime multitasking to 10 microseconds cycle period with the lowest jitter performance. The X-Reatime Engine has multi-processor support, and can be used for versatile application and driver projects. With the special Virtual Code Mapping technology the programming can be done within the familiar development environment (eg Visual C ++). The access to the hardware resources can be made directly from the application level in realtime. Whether IO port, mapped memory, timers or interrupts, all hardware resources are accessable deterministicly (in contrary to a driver solution). Applications in the measurement, control and transmission technology with high data transfer rates and lowest response times are best examples for the application of the realtime extension. Just at the critical platform - CPU combinations of notebooks, the realtime extension shows its strengths. The combination of three methods, depending on the platform, a jitter of less than 10 microseconds can be achieved. On desktop platforms even a jitter of less than 3 micro-seconds is achieved stable.

As with the 32-bit realtime engine, the 64-bit solution also allows the complete realtime programming of resources, such as IO-Space, MappedMemory and DMA of all PC components - both, internal hardware (eg, legacy) and peripheral adapters (eg, PCI, PCIe, PCMCIA, etc). For the programming of plug-and-play components, a stand-alone resource-enumerator was developed. The programming of realtime tasks, the control of hardware components, as well as the programming of Windows routines is done together within the same development environment (e.g. Visual Studio), as an application development. The data exchange between the realtime task and a Windows thread that can be performed with common, synchronized memory areas. The software is installed in a single operation - without complex Windows settings. The software SYDBG for realtime control is available to get started easily with a control system for all available processor cores, as well as with a display of status information. In addition, this software offers the possibility of source code debugging for realtime tasks. With the additional module for jitter analysis SYDBG allows comprehensive monitoring of the realtime engine.

Real-Time Jitter Compensation Technology

By combining three compensation methods, reliable, depending on the platform, a jitter of less than 10 microseconds can be achieved. On desktop platforms even a jitter of less than 3 micro-seconds is achieved stable. Each processor core may be operated as a stand-alone realtime task cluster. Although the X-Realtime Engine requires only a very low jitter, in real time sampling mode an additive jitter arises due to the system. The result of the new compensation method is absolutely amazing - here is the comparison: Without compensation is the additive jitter of the X-Real Time Engine on 20 sampling rates (2 msec update cycle) 200 micro-sec, with a dynamic drift of about 10 micro-seconds per cycle. With compensation of additive jitter of the X-Real Time Engine on 20 sampling rate is (2 msec update cycle) about 15 micro-seconds.
