SHA Sybera Hardware Access

<--- download software, documentation and manuals
The software SHA allows realtime control of hardware resources based on the asynchronous X-Realtime technology. The SHA X-Realtime Engine works without additional hardware under Windows NT,2000,XP and allows realtime multitasking upto 10µsec tasking period with lowest JITTER behavior. The X-Realtime Engine supports multiprocessor platforms, supports PIC and APIC mode and may be used within various application- and driver-projects. With the latest VirtualCodeMapping technology of SHA one can work within the accustomed development environment (e.g. Visual C++). The access off hardware resources can take place directly from the application layer.  Whether IO-Port, Mapped memory, timer or interrupts, all resources can be accessed without loss of time opposite to a driver-solution. Applicationfields in measurement, control - and communication - technology with high data transfer-rates and lowest reaction-time are best examples for the use of SHA.
