inSilicon and MIPS Technologies Pair to Streamline Systems-on-a-Chip Platform Solutions

inSilicon to Bundle and License MIPS Technologies' Processor Cores for Communications Products

SAN JOSE, Calif., July 26, 2000 - inSilicon Corporation (Nasdaq: INSN), a leading provider of communications technology for complex systems-on-a-chip, today announced an agreement with MIPS Technologies, Inc. (Nasdaq: MIPS, MIPSB), a leading provider of industry standard processor architectures for digital consumer and network applications. The agreement allows for the inclusion of MIPS Technologies' embedded processor cores in platform design solutions from inSilicon.

Under the terms of the agreement, inSilicon may license to its customers cores from MIPS Technologies' MIPS32 4K? RISC core processor family bundled as part of inSilicon's platform products, initially focused in the area of broadband access. inSilicon intends to develop application-specific vertical market IP that offers the customer a more complete platform solution.

"The ever-shrinking time-to-market windows and growing complexity are driving the need for system and sub-system IP platforms that include all the necessary components," said Wayne Cantwell, president and CEO of inSilicon. "With this relationship with MIPS Technologies, we will be able to provide our customers with a more complete design solution."

"inSilicon is well positioned, with MIPS Technologies' cores and their communications intellectual property, to provide customers with platform solutions that are easy to integrate," said John Bourgoin, MIPS Technologies, Inc. president and CEO. "We look forward to increased market exposure for the MIPS architecture as part of inSilicon's platforms."

Shrinking market windows and exploding design complexity are driving the demand for increased efficiency of system-on-chip design integration. This agreement propels the current SOC paradigm of obtaining and integrating separate IP elements to a new level of design efficiency. By utilizing "pre-integrated" system- and subsystem-level platforms employing the MIPS CPU IP along with inSilicon's communications technology, SOC designers can simplify complex integrated circuit development and thereby gain significant time-to-market advantages.
