CAMBRIDGE, UK and TAIPEI, TAIWAN -August 01, 2001 -ARM [(LSE: ARM); (Nasdaq: ARMHY)], the industry's leading provider of 16/32-bit embedded RISC microprocessor solutions, and SiS, the leading core logic and graphic chip supplier based in Taiwan, today announced that SiS has licensed the ARM7TDMI® microprocessor core for use in its product range of integrated chipsets for PCs.

SiS currently offers core logic products integrating network and 3D graphics for both Intel and AMD processors and will soon offer a system-on-chip (SoC) solution. This agreement will allow SiS to integrate ARM® intellectual property (IP) into future core logic products for PCs. SiS also plans to use the ARM7TDMI core to develop networking and communication products. This agreement with SIS further underlines the importance of the Asian market to ARM and its commitment to build relationships with companies throughout the region .

"This agreement gives us a good opportunity to strengthen and expand our product portfolio by having access to ARM's industry-proven microprocessor core designs," said Shing Wang, senior vice president, SiS. "By incorporating the ARM core design, we demonstrate to our customers not only our commitment to producing the best core logic products possible, but also our dedication to expanding and developing our current product range."

"This announcement with SiS is the latest in a series of recent agreements with technology companies in Asia, and underlines ARM's commitment to offer the industry's leading microprocessor designs to our Partners in a range of markets around the globe," said Reynette Au, VP, Corporate Marketing, ARM. "SiS has expertise in designing CPUs for the industry's leading architectures and their decision to use ARM technology again demonstrates the adaptability of the ARM microprocessor core for a wide range of consumer applications."

SiS plans to make products based on the ARM7TDMI core available in Q4, 2002.
