DIAB-SDS Now Supports MIPS-Based Processor Cores.

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

Leading Development Tools for Embedded 32-bit RISC 

Cores Now Available For Worldwide Developers of the MIPS(R)

Architecture

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(TM) debugging environment and Diab C, C++, and Java(TM) compiling and Run-Time Analysis solutions for a wide variety of MIPS devices, including MIPS Technologies' (NASDAQ: MIPS) new MIPS32(TM) architecture.

DIAB-SDS compiling, debugging, and Run-Time Analysis technologies are available today as an integrated part of ISI's pRISM+(TM) development environment for the pSOS+(TM) real-time operating system and will be available later this year as a stand-alone tool suite for MIPS applications. Embedded developers using high-performance, cost-effective MIPS-based processors will now be able to benefit from the proven technology, reliability, and expertise afforded by DIAB-SDS' family of software development tools.

"This is a great win for worldwide developers who design with the MIPS architecture, and a significant endorsement of the market reach of MIPS-based cores," said Greg Stoner, manager of applications at MIPS Technologies, Inc. "DIAB-SDS' tools have a long-time reputation for high-performance and high-quality. By extending their coverage to the MIPS architecture, our developers will benefit from the growing list of leading embedded tools options."

"Our announced support of the MIPS architecture is proof of our commitment to broadening the reach of our world-class development tools," said David Stepner, president of DIAB-SDS. "Since our merger-based creation two months ago, DIAB-SDS has moved quickly to open new markets for our more comprehensive development solutions. MIPS-based designs represent one of the most exciting markets for us and we are confident that MIPS Technologies' licensees and customers will find their success rate increasing and time-to-revenue decreasing through the selection of DIAB-SDS tools."

Availability

DIAB-SDS tool support for MIPS series devices is available now as an integrated component of pRISM+ v2.0 from ISI, which includes:

-- Diab v4.3 compiler support for the MIPS R3xxx/R4xxx/R5xxx and

MIPS16 technologies -- SingleStep v7.4 MIPS debugger

DIAB-SDS will offer stand-alone MIPS support as an open solution for any commercial or in-house real-time operating system environment in Q1 2000. The stand-alone suite will feature:

-- Diab D-CC, D-C++, and FastJ compiler suites -- RTA Suite of run-time analysis tools including Run-Time Error

Checker and Profiler -- SingleStep v7.5 debugger -- ROM monitors and key on-chip (JTAG and EJTAG) hardware connection
