MIPS Technologies Acquires First Silicon Solutions (FS2)

Mountain View, CA, September 6, 2005 -- MIPS Technologies, Inc. (NASDAQ:MIPS), a leading provider of industry-standard processor architectures and cores for digital consumer and business applications, today announced it has acquired First Silicon Solutions (FS2), a Lake Oswego, Oregon company as a wholly-owned subsidiary. FS2 specializes in silicon IP, design services and OCI® (On-Chip Instrumentation) development tools for programming, testing, debug and trace of embedded systems in SoC, SOPC, FPGA, ASSP and ASIC devices.

Customers benefit from FS2’s OCI technology that provides deep, system-wide visibility into the inner workings of the SoC, a key factor in enabling successful designs and accelerating time to market. FS2 has been working closely with MIPS Technologies and its customers since 1999 to develop leading-edge system-level debug and trace technologies for MIPS-Based™ cores. This collaboration resulted in the development of the PDtrace™ (Program and Data Trace) on-chip and off-chip trace systems used in the MIPS32® 4KE™, MIPS32 24K® and MIPS32 24KE™ processor core families. In addition to the PDtrace technology, FS2 provides System Navigator probes integrated with software solutions for embedded system development and debug. The company also offers its Logic Navigator™ line of IP and tools for system-wide analysis of advanced processor buses.

“We’re delighted to welcome First Silicon Solutions to the MIPS Technologies family,” said John Bourgoin, president and CEO, MIPS Technologies. “FS2’s innovative system-level debug solutions help our customers’ development efforts and result in faster time to market.for their products. The acquisition will strengthen an already best-in-class capability for a new generation of MIPS products.”

Rick Leatherman, president of FS2 added, “Over the years, FS2 has developed high performance debug tools for embedded markets. This acquisition reinforces and expands the synergies between our two companies to deliver superior system and software design and debug tools to speed our customers’ time to market. We’re excited to join the MIPS Technologies team.”
