ARM Launches Level 2 Cache Controller

24 February 2004

Motorola first to license new ARM solution for Mobile Extreme Convergence

CAMBRIDGE, UK – Feb. 24, 2004 - ARM, [(LSE:ARM);(Nasdaq:ARMHY)], the industry’s leading provider of 16/32-bit embedded RISC processor solutions, announced today at the 3GSM Congress, Cannes, France, the ARM® L210TM Level 2 cache controller. When combined with an ARM processor, the ARM L210 controller has the potential to increase performance by between 25 to 75 percent, thereby extending battery life and reducing memory cost.

Motorola, Inc. was the lead partner in the definition of the L210 controller and is the first ARM Partner to license it.  The ARM L210 controller will be incorporated into Motorola’s Mobile Extreme Convergence (MXC) architecture for 2.5G, 2.75G and 3G mobile handsets and a new category of portable multimedia devices.  MXC incorporates an ™ core together with the ARM L210 Level 2 cache controller.

Motorola has been using the ARM architecture in its products for more than three years, enabling the company to develop advanced high-end mobile devices. Motorola worked closely with ARM to define the optimal cache controller used in the MXC architecture. The addition of this enhanced memory subsystem typically increases the performance by 25 to 75 percent.

When incorporated into Motorola's MXC architecture, the ARM L210 controller enhances performance to meet growing consumer demand for powerful next-generation handsets that maintain optimal levels of battery life. By concentrating all of the modem processing onto a single DSP (single core modem), the MXC architecture is designed to free up the MCU core to enable richer feature sets across a wide range of mobile devices; simplify the software development environment; accelerate time to market; simplify and reduce inter-processor communications; enable increased efficiency via shared and reduced memory requirements; and provide seamless mobility in a small footprint, with low system and development costs.

“This advancement builds on ARM’s high performance road map to extend our strength in performance-driven market segments such as the consumer entertainment and wireless markets,” said Bruce Beckloff, director of Segment Marketing, ARM. “With the addition of the L210 cache controller to a system, ARM enables our Partners to realise the power of our high performance cores, such as the

ARM1136JF-S core in the 550 MHz range, without having to implement an expensive and complex memory system that would increase system cost and power consumption.”

The L210 cache controller reduces the external memory bandwidth requirement of very high-performance CPUs like the ARM1136JF-S core, by requiring fewer CPU memory accesses to go to off-chip memory.  It uses a unified instruction and data cache, supporting level two cache sizes from 128k to 2MB. The L210 controller is compatible with the ARM1136JF-S core, the ARM1136J-S™ core, the

ARM1026EJ-S™ core, and the ARM926EJ-S core.

The ARM L210 level 2 cache controller is available for licensing from ARM immediately.
