DIAB-SDS Broadens Leadership for Motorola Embedded Processors with New Product Support.

SAN JOSE, Calif.--(BUSINESS WIRE)--Sept. 27, 1999--

Leading Development Tools for Embedded 32-bit

Motorola Cores Adds Support For:

--M56651 and M56652

--M-CORE(TM) M300

DIAB-SDS, the market leader in embedded software development tools for 32-bit RISC-based designs, and an independent subsidiary of Integrated Systems, Inc. (NASDAQ: INTS), today announced that it will deliver its popular SingleStep debugging environment and Diab C/C++/Java(TM) compiling and Run-Time Analysis solutions for the Motorola DSP56651 and DSP56652, as part of an integrated solution with Motorola's Suite56 SW development tools. The M56651 and M56652 combine an M-CORE M200 core with a Motorola 56600 DSP in a powerful yet compact package optimized for advanced embedded applications such as next-generation personal communication devices. In addition, DIAB-SDS today announced current support for the new Motorola M-CORE M300 product line with its D-CC/C++/FastJ (Java) compilers and RTA Suite run-time analysis tools.

"We were extremely pleased when, earlier this year, our longtime partners at Diab Data Inc. and SDS merged to create DIAB-SDS. The new round of Motorola M-CORE support shows our mutual commitment to each other's success," said Fred Stotz, third-party tools manager for Motorola SPS' M-CORE Technology Center. "Diab compilers and SingleStep debuggers are highly popular solutions in the Motorola developer community, and a key reason for their success is their ability to provide high-quality, early-to-market tools that are optimized for embedded applications. We applaud their ongoing support for our new product offerings, and we look forward to more successes in the future."

"Our announcement of forthcoming DSP56651/DSP56652 support is an important part of our continuing strategy to be an early provider of the most comprehensive and optimized tools for critical Motorola products," said David Stepner, president of DIAB-SDS. "In this case, we will help enable the first developers taking advantage of the benefits of Motorola's DualCore product strategy, primarily in the wireless communications market. We will also continue our early-to-market support of Motorola developers as well as maintain our leadership in M-CORE compiler usage with support for the new M300.

"According to key 3rd party market research, DIAB-SDS is the leader in providing commercial development tools for the Motorola embedded 32-bit community, specifically for PowerPC(TM), ColdFire(R) and M-CORE applications," added Stepner. "We are firmly committed to supporting major new Motorola SPS developments, and will continue to solidify and increase our dominant share of the commercial Motorola market."
