ZRRT Collaborates With ARM To Integrate JTEK Technology in China Unicom's Next-Generation Java Environment

BEIJING, CHINA AND CAMBRIDGE, UK  - Sept. 7, 2004 - ZRRT, the Chinese mobile technology provider, and ARM [(LSE: ARM); (Nasdaq: ARMHY)], announced today that ZRRT Communications Technology Co.,  Ltd. is collaborating with ARM to integrate the ARM® Jazelle® Technology Enabling Kit (JTEK™) software into ZRRT's Java virtual machine. The ARM JTEK technology will be used to help develop Java mobile phone services for UniJa, a Java-based, value-adding service platform promoted by the strategic alliance of China Unicom, Sun Microsystems and ZRRT.

ARM Jazelle technology enables devices to execute Java byte code directly, so wireless and internet device developers can build in the capability to run high-performance Java technology applications much faster, with limited power and cost penalties. The Jazelle technology will enable ZRRT to provide UniJa with a Java platform, which will be used primarily by China Unicom's 100 million subscribers. The UniJa environment will provide mobile subscribers with rich services with no application compatibility issues between handsets, or intrusion of illegal programs.

"Mobile users demand an ever more engaging experience and Java is the key to capitalizing on this trend, while driving up the ARPU," said Harry Zhou, senior vice-president and chief technical officer, Beijing ZRRT Communications Technology Co., Ltd. "This agreement with ARM accelerates the mass market potential of enriched data services and offers end users a rich selection of mobile applications such as downloadable games, music and video."

"We are looking forward to building on our partnership with ZRRT, to help them provide China Unicom's subscribers with the next generation of Java applications," said Jun Tan, president, ARM China. "Embedded Java technology offers consumers better mobile applications without compromising battery life, which is why ZRRT has chosen to work with ARM and its proven JTEK solution for the UniJa Java environment for mobile phones."
