About the Real-time Subsystem (RTSS)

When RTX64 (Real-Time Extension) is installed on Windows, it enhances support for time-critical tasks by providing a Real-time Subsystem (RTSS) which has the ability to dedicate processors/cores to RTSS processes and threads and communicate with Windows processes and threads.

The Real-time Subsystem (RTSS) provides a priority based preemptive scheduler that is Symmetric-Multiprocessor aware. This allows for scheduling of RTSS threads across all dedicated RTSS processors, while still allowing communication with Windows processes (RTAPI) and drivers (RTKAPI) through standard inter-process communication (IPC) and shared memory.
