OnCore Systems Provides Roadmap for pSOS Developers
PSOS Applications now run in a Protected OS Environment

HALF MOON BAY, CA. - September 25, 2000 -- OnCore Systems Corporation,
developer of the OnCore OS, the most powerful embedded OS of its kind, today
announced the immediate availability of a full-function pSOS applications
programming interface (API), allowing pSOS applications to run on top of the
OnCore Microkernel within a Memory Management Unit (MMU) protected
partition.  The OnCore pSOS API provides pSOS developers with the elegant
transition from a flat memory model RTOS (Real-Time Operating System)
environment onto a modern, crash-resistant microkernel architecture.  This
news also underscores OnCore's commitment to support a growing list of
industry standard APIs that can coexist on the same silicon, without
sacrificing safety and/or real-time characteristics offered by the OnCore OS
microkernel.

This news follows in the footsteps of OnCore's July 26, 2000 announcement,
which noted the immediate availability of a MicroC/OS-II real-time API for
the OnCore OS (see press release on the web at:
http://www.OnCoreSystems.com/pr/20000726_microcos_api.htm).

Beyond extending the useful life of pSOS applications, the OnCore pSOS API
provides additional benefits offered by no other embedded OS.  Using the
OnCore OS as a foundation, enterprise-class operating systems, like Linux,
and RTOS applications each run on top of the OnCore microkernel within their
individual MMU-protected memory partitions.  Using this uniquely innovative
approach, Red Hat Linux application binaries can run simultaneously along
side of real-time pSOS applications.

Using an IBM PowerPC™ 750CX running at 550MHz, a high-priority real-time
pSOS application can preempt any other application in less than
5-microseconds.  Using OnCore's unique approach, system designers can mix an
array of enterprise and real-time applications without sacrificing
mission-critical, real-time characteristics pSOS users have enjoyed for
years.  The OnCore pSOS API joins a growing family of industry standards
supported by OnCore.  RTOS APIs already shipping with the OnCore OS
Development Kit are POSIX, C threads, and MicroC/OS-II.

OnCore's powerful OS has the robustness to support a variety of Linux usage
models called the Linux for Real-Time™ family of products.  These include
using standard Linux, Linux OnCall™, and Linux OnDemand™.  They allow
embedded designers to choose the right fit of memory footprint and
performance.

OnCore also provides the OnVoy™ messaging system that allows robust, open
messaging between separate processors.  OnVoy is an open specification that
allows the simple layering of the OnCore Distributed Interprocess
Communication (DIPC) model on top of legacy environments, including VxWorks,
pSOS, in-house kernels and even "bare" microcontrollers and DSPs with no
RTOS.  With OnVoy, legacy applications are easily and efficiently integrated
into modern networks of processors, and can immediately leverage the
transport-independent communication facilities of OnCore-based
microprocessors.

Like all APIs in the OnCore OS Development Kit, both the pSOS API and OnVoy
are royalty-free components that ship in both binary and source forms.

Future plans from OnCore call for additional RTOS API's and/or ports.  For
those who wish to develop their own APIs for in-house developed RTOSs,
OnCore offers the OnYourAPI™ open-source porting kit for real-time and
enterprise OSs.

Bridging Legacy Systems
The OnCore OS was designed to be a powerful, highly scalable and resilient
embedded operating system.  It enables the migration of legacy RTOS
applications, originally architected for older processors with flat memory
models, to today's advanced microprocessors.  Using this unique approach,
legacy RTOS applications are provided an extended product life, while at the
same time, benefit from the ability to run in a more reliable and robust
embedded environment.

Live Demonstrations
OnCore Systems will be demonstrating the entire OnCore product line at the
NetWorld + InterOp tradeshow in booth #4046 being held in Atlanta, Georgia
and at the Embedded Systems Conference in booth #8101, which is being held
in San Jose, California.  Both exhibitions run concurrently from Tuesday,
September 26 through Thursday, September 28, 2000.
