RTX64

RTX64 extends, but does not modify, the Windows hardware abstraction layer (HAL) by adding a real-time Subsystem (RTSS) to Windows. The RTX64 Subsystem 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.

RTX64 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 between Windows processes (RTAPI) and drivers (RTKAPI) through standard inter-process communication (IPC) and shared memory.
