						For Immediate Release

		TimeSys Announces Mission-Critical 
	   Real-Time Enhancements for TimeSys Linux/RT(TM)

		The Power of Real-Time in Pure Linux(TM)

Pittsburgh, PA May 31, 2000 - TimeSys Corporation today announced the
immediate availability of critical real-time features in TimeSys
Linux/RT(TM) 1.1, a real-time version of the Linux Operating System.
TimeSys Linux/RT is the first complete and open-source solution to
extend the Linux kernel to provide predictable real-time response at the
Linux application layer, thus offering the benefits of native device
drivers and applications.
Additional features include priority inheritance support with the
kernel; TimeTrace(R) support for detailed visualization of operating
system internal events; and Rate-Monotonic Analysis-based (RMA)
mathematical analysis and simulation of real-time architectures via
TimeWiz(TM).
Priority inheritance avoids the unbounded priority inversion problem
that frequently occurs in real-time system designs, and which leads to
timing glitches in fielded products. For example, the NASA's Mars
Pathfinder Rover mission in 1997 nearly failed due to unbounded priority
inversion, but was saved by a single-bit correction uploaded to its
software to enable priority inheritance. The story of the Mars
Pathfinder has been widely distributed on the Internet and is available
at (http://www.cs.cmu.edu/afs/cs/user/raj/www/mars.html). The original
contributors of the techniques to address this problem include Dr. Raj
Rajkumar, cofounder and chairman of TimeSys, and Dr. Douglass Locke,
vice president of technology of TimeSys.

	"As the product cycles become shorter in the Internet age, the ability
to design systems correctly the first time and every time has become
essential. TimeWiz offers both Rate-Monotonic Analysis and
discrete-event simulation, which provide a balanced and disciplined
approach to system design. TimeTrace offers the detailed view of the
time-critical operating system events and metrics that are necessary for
successful application deployment," said Dr. Doug Locke.
	The enhanced product is available for download or purchase from the
company's Web site, www.timesys.com.
