wRTOS and Windows

wRTOS extends, but does not modify, the Windows hardware abstraction layer (HAL) by adding a real-time subsystem (RTSS) to Windows that delivers deterministic, hard real-time performance.

With the exception of its real-time handler RTSS is conceptually similar to other Windows subsystems in that it supports its own execution environment and API.

The HAL extension maintains interrupt isolation between RTSS and Windows, while providing inter-processors interrupt (IPI) communication between the two. The RTSS schedules its tasks to execute on separate processors, without any interference from Windows or Windows processes, but still allows for communication with Windows processes (RTAPI) and drivers (RTKAPI) through standard inter-process communication (IPC) and shared memory.
