EMBEDDED SYSTEMS CONFERENCE, SAN FRANCISCO, Calif., -April 10, 2001- Wind River Systems (NASDAQ: WIND), a leading provider of software and services for connected smart devices, announced today that it intends to offer development tools and runtime support to speed designs of systems containing field programmable gate arrays (FPGA). This extension to Wind River's existing support for RISC/CISC CPUs provides a complete design capability that allows embedded engineers and system architects to select the optimum programmable silicon building blocks for their application requirements.

An increasing number of embedded designs are closely coupling FPGAs and CPUs. This new class of system known as "reconfigurable computing" allows FPGA hardware to be configured with new functionality after the product has been deployed. In this architecture the CPU typically runs system applications while the FPGA manages other computationally intensive tasks. System designers will now be able to choose from a suite of Wind River products to profile bottlenecks and CPU time-intensive tasks in software, and then migrate these sections of code where appropriate into hardware. To facilitate the combined use of CPU's and FPGA's in reconfigurable computing designs, Wind River is developing new solutions including new hardware reference designs, new hardware bring-up tools, timing and profiling tools, code generation tools, and more. These products will be designed to complement the company's market leading Tornado® integrated development environment, (IDE) and VxWorks AE real-time operating system (RTOS). Specific product announcements will be made later this year.

The combination of Wind River technology with partner solutions from Celoxica and Xilinx will set new standards in the industry for embedded system design. Xilinx provides API extensions for VxWorks AE RTOS to facilitate complete control of FPGA content and Celoxica has developed DK1, a "C-to-hardware" design suite that enables direct C-to-hardware synthesis.

"Wind River recognizes that software and hardware design methodologies are merging," said John Fogelin, vice president and general manager of the Wind River Platforms Business Unit. "As these design techniques move toward similar goals of creating faster, more reliable devices, compatibility issues will remain at the forefront of the challenges for embedded designs. Our support for reconfigurable computing development includes providing tools and solutions for the complete product life cycle from hardware bring-up, through application development and remote upgrade capability for deployed reconfigurable products. Wind River is uniquely positioned to provide every type of embedded software developer - regardless of the type of silicon building block used - the tools they need in this challenging and ever expanding market."

A Complete Reconfigurable Platform
Following are some of the components of Wind River's platform to enable reconfigurable computing designs:

• RTOS - Wind River's VxWorks AE RTOS provides the best runtime environment for closely coupled CPU and FPGA systems. Extensions to the API are in development to facilitate the migration of software content from the CPU to an FPGA, and the Xilinx PAVE API for the VxWorks AE RTOS allows FPGAs to be reprogrammed in deployed products.


• Development Tools - Wind River's Tornado IDE is a development platform integrated with VxWorks which includes graphical project workspace and RTOS management tools such as an object browser, runtime analysis tools, debuggers and compilers as well as boot loaders.


• Firmware and Reference Designs - Wind River's visionWARE design tool, a hardware/software integration technology, is specifically designed for developing software that interacts with and controls hardware. visionWARE accelerates and simplifies writing target diagnostics, initialization code, speeding development, manufacturing & test processes.

"Through its extensive WindLink partner program and value chain of products, Wind River is able to provide its customers with a complete design and development solution for customers developing field upgradable applications," said Rich Sevcik, senior vice president of IP cores, service and software, at Xilinx.

ALAMEDA, Calif., April 2, 2001 - Wind River Systems, Inc. (Nasdaq:WIND), a leading provider of software and services for smart connected devices, today announced an agreement with Agilent Technologies (NYSE: A) whereby the two companies will provide seamless integration of Agilent's logic analysis systems with Wind River's visionICE and visionPROBE on-chip debug solutions. The integration allows embedded developers to use visionICE and visionPROBE in conjunction with Agilent's high-performance logic analyzers to retrieve, or "trace" data from the target microprocessor, providing real-time data analysis of the embedded application. The agreement is part of Wind River's strategy to provide complete, end-to-end development solutions that enable customers to bring complex embedded applications to market as quickly as possible.

Wind River has integrated its on-chip debug solutions with Agilent's 16700 series logic analysis systems to enable software engineers to capture real-time trace that can be displayed through a single, convenient Wind River graphical user interface (GUI). Developers can use visionICE / visionPROBE to control the Agilent logic analyzer as well as the target system, with all data acquired from the system transmitted to a single Wind River GUI.

According to a recent market study, over 50 percent of embedded developers responding to the survey had used a logic analyzer in the last 12 months and 65 percent of those developers had used an Agilent logic analyzer. Embedded developers use real-time trace to locate and fix hard-to-find bugs that often occur when bringing up complex hardware and integrating software with custom hardware. Because the processing power and speeds of today's modern microprocessors have increased so dramatically, common debug tools are often unable to retrieve accurate real-time trace information. Agilent's logic analysis systems allow hardware engineers to acquire crucial data regarding microprocessor activity and the target application with even the fastest microprocessors.

"As leaders in their respective markets, Wind River and Agilent have recognized that customers use a variety of tools to debug complex systems. These new solutions provide customers with both the functionality and flexibility they need at the crucial hardware/software integration phase of product development," said Alois Hauk, vice president of Agilent's Design Validation group. "Design teams can now get more utilization out of their Agilent logic analyzer while also obtaining a trace view through the Wind River user interface using the logic analyzer as a bus data capture tool. Agilent's commitment to providing the fastest logic analysis capabilities means customers will have solutions when the latest embedded microprocessors become available."

"The real-time nature of embedded systems requires the visibility offered by logic analyzers," said Peter Dawson, vice president and general manager of Wind River's Hardware / Software Integration business unit. "The challenge though, has been presenting the data acquired by the analyzer in a format familiar to software engineers. By Integrating Agilent's high-performance logic analysis systems with Wind River's visionICE / visionPROBE debug systems, developers can now correlate system activity with their source code and more quickly isolate real-time bugs in a system, significantly shortening the time required to get a stable product design to market."

In addition to displaying real-time trace in the Wind River trace window (LA TRACE), powerful cross triggering between visionICE / visionPROBE and the Agilent logic analyzer enables the developer to trace up to a breakpoint or stop the target when a real-time event is captured. Once the real-time trace data is acquired from the target system, developers can use the visionICE / visionPROBE development tools to test and debug the application with hardware diagnostics and software tests.

Advanced features of the Wind River LA TRACE window include the ability to display trace in raw code machine, source code or mixed mode (displays machine and source), and search capabilities within the trace acquisition to search for specific function execution, variable access, specific code addresses, or data values. Trace can also be filtered to select which function to display and acquisition of multiple traces in a single window is supported.

The visionICE and visionPROBE development tools are fully integrated with Wind River's VxWorks® real-time operating system and the Tornado® integrated development environment, providing a complete end-to-end development platform. The tools are also members of Wind River's "stand-alone" class of development tools, and thus may be used regardless of the customer's RTOS.

Availability
LA TRACE is a component of the GUI portion of Wind River's visionICE / visionPROBE tool suites and will be part of the product's standard distribution package at no additional charge. LA TRACE is currently in beta supporting the PowerPC microprocessor family, with additional architectures to be added throughout 2001. The product will be fully available early this summer. The integrated technology will be featured by Agilent's (booth # 918) at the upcoming Embedded Systems Conference being held at the Moscone Convention Center in San Francisco, CA, April 10-12.

ALAMEDA, Calif., April 2, 2001 - Wind River Systems, Inc. (Nasdaq:WIND), a leading provider of software and services for smart connected devices, today announced an alliance with Tektronix, Inc. (NYSE: TEK), a leader in the development of logic analysis systems for the embedded market, whereby the two companies will provide seamless integration of Tektronix TLA Series logic analyzers with Wind River's visionICE and visionPROBE on-chip debug solutions. The integration allows embedded developers to use visionICE and visionPROBE in conjunction with Tektronix high-performance logic analyzers to retrieve, or "trace" data from the target microprocessor, providing real-time data analysis of the embedded application. The alliance is part of Wind River's strategy to provide complete, end-to-end development solutions that enable customers to bring complex embedded applications to market as quickly as possible.

Wind River has integrated its on-chip debug solutions with Tektronix´ TLA600 and TLA700 Series of logic analyzers to enable software engineers to capture real-time trace that can be displayed through a single, convenient Wind River graphical user interface (GUI). Developers can use visionICE / visionPROBE to control the Tektronix logic analyzer as well as the target system, with all data acquired from the system transmitted to a single Wind River GUI.

According to a recent market study, over 50 percent of embedded developers responding to the survey had used a logic analyzer in the last 12 months and 42 percent of those developers had used a Tektronix logic analyzer. Embedded developers use real-time trace to locate and fix hard-to-find bugs that often occur when bringing up complex hardware and integrating software with custom hardware. Because the processing power and speeds of today's modern microprocessors have increased so dramatically, common debug tools are often unable to retrieve accurate real-time trace information. Tektronix logic analysis systems allow hardware engineers to acquire real-time digital, analog and software data with even the fastest microprocessors.

"By partnering with an industry leader such as Wind River, Tektronix enables its customers to shorten their development cycles and overcome time-to-market challenges when developing next-generation embedded systems architectures," said Craig Overhage, vice president, Digital Systems Business Unit, Tektronix, Inc. "Tektronix provides embedded developers complete unmatched visibility and analysis of their development system that includes correlated source code to real-time software execution. The TLA Series logic analyzer's Windows 2000 PC platform running visionICE and visionPROBE provides a powerful, compact development system for rapid debugging and verification of embedded system designs."

"The real-time nature of embedded systems requires the visibility offered by logic analyzers," said Peter Dawson, vice president and general manager of Wind River's Hardware / Software Integration business unit. "The challenge though, has been presenting the data acquired by the analyzer in a format familiar to software engineers. By Integrating Tektronix´ high-performance logic analysis systems with Wind River's visionICE / visionPROBE debug systems, developers can now correlate system activity with their source code and more quickly isolate real-time bugs in a system, significantly shortening the time required to get a stable product design to market."
