The INtime Real Time Operating System (RTOS) family is based on a 32-bit RTOS conceived to run time-critical operations cycle-times as low as 50μs. INtime RTOS runs on single-core, hyper-threaded, and multi-core x86 PC platforms from Intel and AMD. It supports two binary compatible usage configurations; INtime for Windows, where the INtime RTOS runs alongside Microsoft Windows®, and INtime Distributed RTOS, where INtime runs one.
Like its iRMX predecessors, INtime is a real-time operating system, and like DOSRMX and iRMX for Windows, it runs concurrently with a general-purpose operating system on a single hardware platform.
History
=Initial Release=
INtime 1.0 was originally introduced in 1997{{Cite web |url=http://www.thefreelibrary.com/RADISYS+ships+INtime+to+customers+worldwide.-a019609157 |title=RADISYS ships INtime to customers worldwide. |access-date=2014-02-05 |archive-date=2014-02-22 |archive-url=https://web.archive.org/web/20140222135306/http://www.thefreelibrary.com/RADISYS+ships+INtime+to+customers+worldwide.-a019609157 |url-status=dead }} in conjunction with the Windows NT operating system. Since then it has been upgraded to include support for all subsequent protected-mode Microsoft Windows platforms, Windows XP to Windows 10.
INtime can also be used as a stand-alone RTOS. INtime binaries are able to run unchanged when running on a stand-alone node of the INtime RTOS. Unlike Windows, INtime can run on an Intel 80386 or equivalent processor. Current versions of the Windows operating system generally require at least a Pentium level processor in order to boot and execute.
=Version 2.2=
After spinning off from Radisys in 2000{{Cite web |url=http://www.thefreelibrary.com/TenAsys+Spins+Off+Real-Time+Software+Business+from+RadiSys...-a062290008 |title=TenAsys Spins Off Real-Time Software Business from RadiSys Corporation |access-date=2014-02-05 |archive-date=2014-02-22 |archive-url=https://web.archive.org/web/20140222135702/http://www.thefreelibrary.com/TenAsys+Spins+Off+Real-Time+Software+Business+from+RadiSys...-a062290008 |url-status=dead }} development work on INtime continued at TenAsys Corporation. In 2003 TenAsys released version 2.2 of INtime.[http://www.tenasys.com/index.php/tenasys-information/press-releases/item/tenasys-corporation-announces-intimereg-version-22 TenAsys Corporation Announces INtime® Version 2.2 ]
Notable features of version 2.2 include:
- Real-time Shared Libraries, or RSLs, which are the functional equivalent of the Windows Dynamically Loaded Libraries, or DLLs.
- Support for the development of USB clients, and USB host control drivers for OHCI, UHCI and EHCI (USB 2.0) devices.
- A new timing acquisition and display application called ""INscope"" is released.
