Implementing the Win32 API over a POSIX Real-Time OS
After presenting the advantages and drawbacks of the
different possible solutions to extend Windows NT to support Real-Time
Applications, this article explains the solution chosen by QNX. It is based
on the port of the Win32 API over a QNX kernel. To ensure the stability
of the solution for the future an effort to normalise the Win32 API has
been started.

Getting real with NT: Approaches to Real-Time Windows-NT
This article presents the Radisys approach to extend
Windows NT to support Real-Time applications. After presenting the seven
possible means to extend Windows NT, the article explains the solution
chosen by Radisys. It is based on modifying the HAL and taking advantages
of the hardware tasks offered by the Intel processors.

Extending Windows/NT for Embedded and Hard Real-Time Systems
Open PC based architectures are presenting unprecedented
opportunities for positive change in the nature of dedicated systems in
the fields of industrial automation, telecommunications, point-of-sale
and others.
The opportunity for Windows/NT to become the dominant
operating system for open PC based architectures in these markets will
be examined. Extensions to Windows/NT are under development to increase
the speed and extent of its market penetration and acceptance.
VenturCom concludes that some hard real-time, scalability,
and embedded operation extensions are required to be made to Windows/NT
in order to achieve sub-millisecond response times, and to reduce hardware
resource requirements while maintaining full compatibility with the enormous
range of software written for Windows/NT.
VenturCom, with over 15 years experience in providing
real-time and embedded systems technology for builders of dedicated systems,
has signed marketing and technical agreements with Microsoft to produce
and sell the development tools and extensions required.

Chief Technology Officer, Naren Nachiappan, Vice President, VenturCom.

LP-RTWin
The LP-RTWin Toolkit uses a simple hardware expansion
module that can be plugged into a PC to achieve Hard real-time deterministic
responses in Windows based products. The real-time extension is based on
a Non Maskable Interrupt ISR. Therefore deterministic response in the microseconds
region can be achieved.

LP-VxWin: VxWorks Together with Windows on the same PC
This article deals with how LP Elektronik added Real-Time
features to Windows and Windows NT. Three solutions are covered, combining
WindRiver OS (VxWorks) and Microsoft OSes. The first solution could be
qualified as a soft real-time solution, whereas the two last ones could
be considered as hard real-time. To reach this level of predictability
these two solutions need extra hardware.

Nucleus MNT and Nucleus VNET: Windows NT and 95 based Version of
Nucleus PLUS
More and more companies would like to develop their software
at the same time as their hardware, so that their product can be released
much faster.
With the introduction of Nucleus MNT and Nucleus VNET
is it possible to prototype the software without having all the hardware
equipment that is needed for the embedded system.
