RTX64 HAL Extension
RTX64, 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.
This component provides the ability for isolation of system resources from Windows by providing RTX64 with the ability to dedicate processors/cores to real-time applications. It maintains interrupt isolation between RTSS and Windows. Except setting up RTSS processors/cores to run in IA-32e mode/64-bit sub-mode, the real-time HAL extension supports high-resolution clocks and timers for RTSS.
Other real-time HAL extension features include: a software interrupt mechanism between RTSS and Windows; basic exception management; system-normal shutdown and dump file support; and various enhancements for determinism.
