PLX Technology and Jungo Software Technologies Team to Provide Full Range of 66MHZ PCI Development Tools

Sunnyvale, Calif., March 12, 2002- PLX Technology, Inc. (NASDAQ: PLXT), the leading supplier of high-speed interconnect silicon and software to the communications industry, and Jungo Software Technologies, Inc. a leading provider of driver development tools, today announced an agreement to include Jungo's WinDriver toolkit with two new PLX® Rapid Development Kits (RDKs), for PLX's PCI 9056 I/O Accelerator chip. The combination of the new PLX PCI 9056RDK-LITE, CompactPCI 9056RDK-860 RDK and a fully functional 30-day evaluation version of the WinDriver v5.04 device driver development toolkit, provides system designers and software developers with a complete environment for developing high-performance 66MHz PCI and CompactPCI telecommunications and networking products based on the PCI 9056.

With the WinDriver v5.04, Jungo extends its broad support for PLX's family of PCI I/O Accelerator devices to include the 32-bit, 66MHz PLX PCI 9056. The software provides the tools to develop high-performance PCI device drivers for Microsoft® (NASDAQ: MSFT) Windows® 98/Me/2000/XP/NT and CE, Linux, Sun® (NASDAQ: SUNW) Solaris®, and Wind River Systems (NASDAQ: WIND) VxWorks® embedded operating systems.

Jungo's WinDriver software features a graphical development environment, intuitive application programming interfaces (APIs), hardware diagnostic services, debug utilities, and device driver samples. Additionally, it includes libraries of code customized for PLX PCI devices that provide pre-programmed registers, interrupt handling, and master/slave direct memory access to further accelerate driver development.

"With WinDriver v5.04, the 9056RDK-LITE and CompactPCI 9056RDK-860, Jungo and PLX are providing an unprecedented driver-development platform for 66MHz embedded systems using the PCI 9056," said Ophir Herbst, general manager of the Software Tools Division at Jungo. "Embedded-system and board developers now will have access to the most advanced driver technology, eliminating the barriers to developing drivers for a new operating system."

PLX Technology's PCI 9056RDK-LITE and CompactPCI 9056RDK-860 RDKs contain proven software and hardware building blocks to accelerate product development. PLX offers extensive host-side driver development software and local-side RTOS support and board support packages on its software development kit (SDK) CD-ROMs included in the RDK. Additionally, each RDK includes a fully functional board, complete design documentation and design files enabling a user to replicate all, or part of, the design.

"The combination of Jungo's driver development toolkit and PLX high-performance, standards-based PCI silicon and rapid development kits provide our customers with powerful tools that enable them to integrate PCI connectivity into their own products in the shortest possible time," said Jeff Goldberg, marketing manager at PLX. "Anyone who visits the Jungo booth at the Embedded Systems Conference this week in San Francisco can see a demonstration of this complete software-hardware solution."

(The WinDriver v5.04, 9056RDK-LITE and CompactPCI 9056RDK-860 complete software-hardware solution will be demonstrated in the Jungo booth, #4667, at the Embedded Systems Conference, San Francisco, March 13-16, 2002.)
