TimeSys Launches TimeSys Linux/RT* for 
Embedded/Real-Time Applications

The Power of Real-Time in Pure Linux

Pittsburgh, PA May 16, 2000 - TimeSys Corporation today announced the
immediate availability of its TimeSys Linux/RTÔ 1.0, a real-time version
of the Linux* Operating System. TimeSys Linux/RT is the first complete
and open-source solution that extends the Linux kernel to provide
predictable real-time response entirely from the Linux OS.
Dr. Raj Rajkumar1, cofounder and chairman of TimeSys, stated, "TimeSys
Linux/RT directly extends the Linux kernel, rather than adding a
non-Linux RTOS layer between Linux and the system hardware. By enhancing
the actual operating system, engineers can build hard real-time systems
using TimeSys Linux/RT, while enjoying the reliability, stability and
the wide availability of drivers and applications for the Linux OS." 
	The TimeSys Linux/RT distribution includes subsystems that combine to
offer a scalable and highly innovative approach to meeting real-time and
QoS (Quality of Service) constraints. Developers can combine these
subsystems to handle a variety of application requirements from small
footprint to full-featured architectures. That most 
critical subsystem is the Resource Kernel (RK), originally developed at
Carnegie Mellon University. The RK supports fixed-priority scheduling
(with 256 priorities) and priority inheritance, characteristics that can
be used for constructing systems to provide guaranteed and bounded
response times. The RK supports high-resolution timers and clocks and
offers unique support for a Temporal Firewall that provides guaranteed
Quality of Service for application execution.
	"Response time is becoming more and more critical in an ever-increasing
number of embedded applications, whether or not their developers
perceive them as real-time. Developers can now ensure that response
times can be met predictably, without depending on only error-prone
testing and tuning at the end of the system integration cycle," said Dr.
Doug Locke2, TimeSys vice president of technology.
	TimeSys Linux/RT distribution, along with TimeSys' SuiteTimeÔ family of
products, provide a strong foundation for successfully building embedded
real-time systems with predictable timing properties the first time,
every time, while offering significant cost savings during integration
and testing.
	"Many of our customers who are building components of the
telecommunications infrastructure and embedded multimedia devices are
looking for effective platforms, tools and expert support to leverage
the benefits of the open-source Linux OS. We are confident that TimeSys
Linux/RT will meet their needs," said Srini Vasan, cofounder and CEO of
TimeSys. "Our forthcoming products and tools, including a real-time Java
virtual machine will provide comprehensive solutions to our customers."
	TimeSys will continue to release code modifications and to provide
enhancements to the open-source community.
Pricing and Availability
	The TimeSys Linux/RT distribution and supporting tools, TimeWiz and
TimeTrace, are available immediately from TimeSys. The distribution,
available free from http://www.timesys.com for downloading, is also
available in three different editions for purchase, all of which come
with limited installation support. The Standard Edition consists of the
TimeSys Linux/RT distribution on two CDs and is priced at $49.00(US).
The Deluxe Edition, priced at $99.00(US), adds hardcopy user and
programmer manuals to the distribution. The Professional Edition is
priced at $199.00(US) and adds extended installation support, TimeTrace
(a measurement and visualization tool) for TimeSys Linux/RT and a
T-shirt. TimeSys also provides a complete set of customization,
consulting and training services. Contact TimeSys for further details.

1 Dr. Rajkumar is an internationally recognized expert in the embedded
real-time systems domain Among other accomplishments, he is the
co-inventor of the family of priority inheritance protocols to avoid
priority inversion problems in real-time systems. He was a key member of
the team that developed and popularized the Rate Monotonic Analysis
(RMA) approach to build predictable real-time systems. He also led the
development of the microkernel-based Real-Time Mach operating system
that supports the FreeBSD Unix environment at Carnegie Mellon
University.
