Microtec Research Announces Commitment To Support New Motorola PowerPC
Processor Variant

SANTA CLARA, Calif.--(BUSINESS WIRE)--July 27, 1995--Microtec Research,
Inc., (NASDAQ:MTEC) a leading supplier of software development tools and
operating systems for embedded applications, today announced it will
support the MPC821 high-performance, integrated PowerPC processor from
Motorola.

Support will include Microtec's full line of development environments, XRAY
Debugger, compiler package, and well-known VRTX operating system.
Microtec's software products address the special needs of embedded systems
developers and satisfy each phase of the development process through
coding, debugging, hardware integration, and deployment.

"The PowerPC processor is quickly gaining marketshare in embedded
applications," said Gail Hamilton, vice president of marketing for
Microtec Research. "The MPC821 is considered a next- generation PowerPC
processor and is positioned to excel in low-power, portable, and personal
communication products."

The following products will be released for the MPC821 starting calendar
year Q196.

XRAY MasterWorks is an integrated C and C++ development environment and is
the first programming environment designed specifically for embedded
software applications. In addition to the industry-standard XRAY Debugger
and C/C++ compilers, XRAY MasterWorks includes: Source Explorer, a
graphical program analyzer, XRAY Make, a graphical build tool; XRAY Source
Code Management Interface, a graphical interface to source code manager.

Spectra is an open cross-development backplane that represents the first
application of a client-server architecture to real-time and embedded
software development. It permits company-wide standardization by
supporting development for a wide range of environments and its open
interfaces increase extensibility and facilitate the preservation of
existing code. When used with XRAY MasterWorks, developers will receive
the many benefits of rapid edit-compile-debug combined with versatile
host/target connectivity. Users also gain the ability to debug optimized C
and C++ applications with full knowledge of the run-time environment. With
the Spectra backplane, we will support popular single-board computers
based on the PowerPC processor.

XRAY Debugger is an industry-standard debugger for source-level debugging
of optimized code. XRAY Debugger supports the analysis and debug of
programs written in C and C++, as well as assembly language. It provides a
window-oriented debug environment, allowing the user to step through and
simultaneously view source code, continuously monitor variables and
expressions, trace function calls, and set simple and complex
breakpoints.

ANSI C and C++ compilers assist in the development of efficient, portable,
and easy-to-maintain programs for microprocessor-based systems. The
compiler generates assembly language code that is further processed by the
Microtec Research assembler and linker. The output of the linker is an
absolute object module that can be downloaded to the target system, a
debugger, a PROM programmer or an in-circuit emulator. The C++ Compiler is
an advanced, optimizing compiler which supports reentrant programs.

The VRTX/OS 3.0 real-time operating system includes VRTXsa, a
high-performance, leading real-time operating system and STREAMS-based
networking for excellent portability and real-time response. VRTXsa is
based on a leading-edge microkernel technology, the Nanokernal. The
Nanokernal is preemptible and offers high-speed, deterministic response to
time-critical system calls contributing to safety and predictability of
embedded software designs based on VRTXsa.
