BroadLight's Newly Released BL2000 GPON System-on-Chip Incorporates MIPS Processor

BroadLight Delivers Industry’s First GPON SoC Designed for Cost-Sensitive ONT Applications with the MIPS32® 4KEc® Processor Core
MOUNTAIN VIEW, CA. , July 26, 2005 – BroadLight, Inc. and MIPS Technologies, Inc. (NASDAQ: MIPS), today announced that BroadLight licensed the MIPS32 ® 4KEc ® processor core for use in its BL2000 GPON (Gigabit Passive Optical Network) and BPON (Broadband Passive Optical Network) SoCs. By incorporating the 4KEc core, BroadLight was able to significantly reduce development cost and speed time to market with the industry’s first complete end-to-end GPON solution, which will be delivered to its first tier customer base by December 2005.

According to a recent PON Equipment forecast report from Infonetics Research, worldwide Optical Line Terminal (OLT) and Optical Network Terminal (ONT) PON equipment revenue hit $525 million in 2004, and is projected to grow 310% to $2.2 billion in 2008, with port shipments reaching over 8 million.

“We chose the MIPS architecture because it met all of our high-end telecom requirements and was the perfect processor for running our BL2000 PONmaker software for ONT and PON,” said Eli Weitz, vice president of VLSI for BroadLight. “In addition, we were extremely pleased throughout the entire design, verification and layout processes. Based on this experience and due to the success of our BL2000 design and development effort, we would certainly collaborate with MIPS Technologies on future products.”

“System vendors are increasingly turning to Passive Optical Networks to deliver cost-effective next generation broadband solutions and BroadLight is an acknowledged leader in PON components,” said Russ Bell, vice president, marketing for MIPS Technologies. “We’re delighted to have had the opportunity to play an integral role in the development of an SoC that will have significant impact on an exploding market.”

About the MIPS32 4KE Core Family
The MIPS32 4KE family of cores offers an ideal solution for the development of high-performance, low power-consumption and highly-integrated chipsets for customer-end applications. The 4KE Pro cores feature the CorExtend™ capability, enabling designers to add user-defined instructions.MIPS32® 4KE™ family of synthesizable 32-bit cores offer performance of 1.5 Dhrystone MIPS/MHz, enabling cutting-edge applications.

• MIPS16e™ code compression allows designers to reduce the memory requirements for their application by as much as 40 percent.
• Cores can be configured with up to 64KB instruction and 64KB writeback data cache for more flexibility and higher performance.
• A coprocessor 2 (COP2) interface enables easy coprocessor connection and support.
• Extensive clock gating reduces power consumption without reducing application performance.
• BIST, scan and Enhanced JTAG (EJTAG) debug with trace and fast download enable quick and easy debugging.
• Can be ported to any silicon process.
• All major operating systems and compiler tool chains and hundreds of third-party development tools support the MIPS architecture.
