METROWERKS RELEASES NEW DEVELOPMENT TOOLS FOR MOTOROLA’S POWERPC EMBEDDED
MICROPROCESSORS

AUSTIN, Texas-March 10, 1997-Metrowerks Inc. (NASDAQ: MTWKF, TSE/ME:MWK)
one of the world’s leading providers of software development tools, today
announced CodeWarrior for PowerPC Embedded Systems, an Integrated
Development Environment (IDE) supporting Motorola’s MPC 8xx PowerPC family
of embedded processors. Motorola and Metrowerks will be showing the new
tools at the Embedded Systems Conference East in Boston, MA from March
10-12, in the Motorola booth, #304.

Hosted on Windows NT 4.0, Windows 95 and Mac OS, CodeWarrior for PowerPC
Embedded Systems allows programmers to build applications for a variety of
portable electronic devices using the Motorola MPC 8xx series of
microprocessors. The CodeWarrior IDE offers a powerful suite of programming
tools including an integrated project manager, text editor, optimizing C
compiler, linker, source/assembly-level debugger and online references.
CodeWarrior for PowerPC Embedded Systems works with Motorola’s 821/860 ADS
development board, providing users with interactive testing support.
Debugging can be implemented using either a Background Debug Mode (BDM)
cable, or Metrowerks’ target resident kernel technology. The target
resident kernel is a software debugger monitor for use with MW Debug, a
source-level host debugger with a graphical user interface.

“CodeWarrior provides PowerPC customers with a powerful set of development
tools for the 8xx family,” said Ken Edwards, marketing manager, Portable
Systems Operation at Motorola. “Together we offer the embedded marketplace
a complete solution for developing next-generation applications.”

“We are proud to introduce CodeWarrior for PowerPC Embedded Systems,” said
Jean Belanger, chairman and chief executive officer of Metrowerks.
“Broadening our product offering to include tools for Motorola’s MPC 8xx
series of embedded processors not only provides embedded PowerPC developers
with a new low-cost, high-performance development solution, but underscores
our commitment to becoming a key tools provider in the embedded systems
space.”
