Accelerated Technology, Lexra and Embedded Performance Announce Cost-effective Solution For Developers of Networking Applications.

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

Embedded Market Leaders Team Up to Provide Nucleus PLUS Real-Time

Operating System Support for Lexra RISC Cores

Accelerated Technology Inc., a leader in source code and non-royalty based real-time operating system (RTOS) software products, Lexra, a leader in processor cores for embedded applications and Embedded Performance Inc., a leader in development tools for RISC processors, announce today the integration of the Nucleus PLUS RTOS with the Lexra LX4180 32-bit RISC core family, with software debug support from Embedded Performance Inc.

The combination of Nucleus PLUS and the LX4180 RISC processor will benefit customers in compute-intensive applications such as networking, where performance and a cost-effective solution are important. The debug support provided by the Embedded Performance's EDB debugger and MAJIC(tm) EJTAG-based in-circuit emulation system will further accelerate time-to-market for these applications.

"Lexra is rapidly gaining design wins," said Neil Henderson, president of Accelerated Technology, Inc. "We see a great deal of synergy in the applications we're pursuing, and we anticipate a strong business environment with Lexra's products."

Lexra's LX4180 is an R3000(R)-class processor core that executes the MIPS I(tm) instruction set(a) and supports MIPS16(tm) code compression. The LX4180 offers 155 MHz performance on a typical .25 micron process, with a die size of 2.75 mm2 and power consumption under 275 mW. An optional Multiply-Accumulate unit and EJTAG debug interface are available. With over 15 licensees worldwide, Lexra's processors are easy to extend and customize, highly portable across diverse silicon processes and easy to integrate using off-the-shelf ASIC design tools.

"We share Accelerated Technology's vision of providing cost-effective solutions based on leading edge technology, with a business model geared to ease-of-ownership," said Charlie Cheng, president and CEO of Lexra. "Adoption of Nucleus PLUS has skyrocketed in the past year, and we're excited to be working with this leading company."

Accelerated Technology's Nucleus PLUS is a real-time, pre-emptive, multitasking kernel designed for time-critical embedded applications. The Nucleus family of software includes kernels, networking, graphics, file system, and Internet products, all designed to get the developer's application up and running quickly and have the product to market faster.

"The Lexra architecture continues to gain popularity throughout the world as a basis for SoC applications," said Norbert Laengrich, CEO of Embedded Performance Inc. "We are excited to be part of a complete off the shelf solution for these designers, and we are pleased to be able to include the Nucleus products with our Lexra Development Boards."

Embedded Performance's MAJIC in-circuit emulator provides access to the internal state of a deeply embedded LX4180, through the standard EJTAG interface. MAJIC provides support for PC trace at speeds up to 100 MHz, high-speed download of application code, and full compatibility with Embedded Performance's EDB Source Level Debugger. EDB is a complete source level debugging environment, which now includes support for debugging software developed to run on the Nucleus PLUS real-time operating system. Development boards for Lexra processors will now include an evaluation version of Nucleus PLUS.
