Toshiba Licenses ARM11 Family Processor

ARM technology to be used in development of ASICs for consumer electronics and network systems

TOKYO, Japan and CAMBRIDGE, UK, Nov. 8, 2004 - Toshiba Corporation and ARM [(LSE: ARM) (Nasdaq: ARMHY)], today announced that Toshiba has licensed the ARM1136J-S™ processor. Toshiba will use the ARM1136J-S processor to develop Application Specific Integrated Circuits (ASICs) for products such as consumer electronics and network systems.

The ARM1136J-S processor's improved branch prediction and additional execution units provide increased efficiency, resulting in overall superior performance. In addition, by using the Single Instruction Multiple Data (SIMD) instructions, the core can execute certain algorithims, such as multimedia processing, up to three times as fast than its predecessors.

Since 1998, Toshiba has licensed the ARM7TM, ARM9TM, and ARM10™ family processors for numerous applications ranging from mobile communications to consumer electronics. This announcement demonstrates Toshiba's commitment to the ARM11™ family for the development of system ASICs. This agreement includes an option for Toshiba to license other ARM11 family processors.

"ARM is clearly a strategic partner in Toshiba's semiconductor business," said Yutaka Murao, General Manager of System LSI Division I at Toshiba's Semiconductor Company. "In response to customer demand, Toshiba has expanded its licensing agreement with ARM to include the higher performance ARM11 family, starting with the ARM1136J-S processor. The ARM11 family is ideal for applications such as mobile phones, consumer electronics and networking systems."

"ARM continues to expand its market reach in Japan," said Hiroyuki Uchimura, managing director, ARM K.K. "By having the ARM11 family of high performance, low power processors included in Toshiba's line up of ASICs, ARM will be able to further accelerate industry adoption of the ARM® architecture, in key markets like consumer electronics and wireless devices."
