ALAMEDA, Calif. Sept. 3, 2002 - Wind River Systems, Inc. (Nasdaq: WIND), a leading provider of software and services for creating connected devices, today announced a substantial upgrade to its industry leading Tornado integrated development environment and VxWorks real-time operating system (RTOS). Wind River's newest offering, Tornado 2.2, is the most dependable and reliable RTOS and embedded tool set on the market today. Additionally, Tornado 2.2 will be the basis for all of Wind River's "Tornado" application specific platforms, such as Tornado for Managed Switches.

"Given today's demanding market conditions, customers must look to companies that can increase efficiencies by providing highly integrated, reliable, well tested and globally supported products. To meet these demands, Wind River invested significant engineering resources to enhance Tornado and VxWorks," said Tony Tryba, vice president and general manager of Wind River's Embedded Technologies business unit. "Our customers can turn to Wind River for the most reliable and comprehensive products available in the embedded software space."

Tornado 2.2, which includes VxWorks 5.5, provides customers with an unmatched set of embedded development tools, operating system technology, networking components, middleware and complimentary WindLinkTM partner technologies. These technology enhancements further set the standard for embedded development, and are being offered to customers under Wind River's standard maintenance agreement at no additional charge. New customers receive these advantages as well.

To assist customers with optimizing the run-time software, Wind River has improved its tools suite to increase developer productivity and eliminate risk. These tools include: Tornado dynamic visualization, RTOS event and object analysis, Application data and event analysis, code coverage analysis, memory analysis, and source code execution analysis tools. Wind River further enhanced the run-time software by including file systems, Java and graphics support, I/O management, multiprocessing capabilities, virtual memory, POSIX standard support, connectivity options, and networking protocols.

In addition to meeting customer needs with thousands of general code improvements, enhanced features of the Tornado 2.2 include:

• Updated version of VxWorks RTOS (VxWorks 5.5) builds on the industry's most popular real-time operating system to deliver unbeatable reliability and performance. New events feature helps customers manage complex application interactions.


• Upgraded GNU and newly integrated DiabTM compiler support for superior C/C++ support, improved ANSI/ISO standards compliance and smaller, tighter code.


• Support for the latest derivatives of the industry's most popular RISC and CISC architectures including PowerPCTM, MIPS, ARM, Hitachi SuperHTM and Intel Pentium processors.


• Support for the latest host development environments including Solaris 2.8, 2.9 and Windows XP Professional.


• New real-time visualization package (optional) offers enhanced application problem solving capabilities through advanced multi-view triggering facility.

The volatile economy has placed even greater pressure on the fragmented electronics industry. Along with the traditional challenges of increased system complexity and intense time-to-market pressures, customers must deliver their products on time with fewer resources. With that in mind, Wind River delivers its new Tornado 2.2 offering to reduce development costs, decrease time to market and lengthen the time in market.

Total System Integration
More than 50 WindLink partner companies have integrated and tested more than 100 of their products with this new Tornado 2.2 release, an effort that sets a new standard for creating a value chain of pre-tested and complimentary products for developers.

"We look to Wind River to provide reliable embedded technology that complements our own market-leading software development tools," said Steve Saunders, vice president engineering, Technical Software Products, Rational Software. "The Tornado 2.2 development environment delivers on Wind River's leadership position by providing a dependable and robust platform for customers using Rational Suite Development Studio RealTime Edition. The combination of our respective technologies provides a comprehensive solution for the entire product engineering cycle and a platform for customer success."
