Datang Mobile Licenses Express Logic's ThreadX(R) RTOS for 3G-Wireless Phone Handsets.

SAN DIEGO -- Express Logic, Inc., the worldwide leader in royalty-free real-time operating systems (RTOS), today announced that it has entered into a software license agreement with Datang Mobile Communications Equipment Co., Ltd. (Datang Mobile), a leading telecommunications corporation in China.

Under this agreement, Datang Mobile is licensed to use Express Logic's ThreadX(R) RTOS in its products for the TD-SCDMA (Time Division - Synchronous Code Division Multiple Access) field. TD-SCDMA, proposed by Datang Telecom Technology and Industry Group on behalf of the Chinese government, was approved by the International Telecommunication Union (ITU) in May 2000 and by the 3rd Generation Partnership Project (3GPP) in March 2001 as one of the 3G mobile communications standards. TD-SCDMA is the Chinese contribution to the ITU's IMT-2000 specification for third-generation (3G) wireless mobile services.

Datang and Express Logic also are entering into extensive discussions intended to enable Datang Mobile to distribute Express Logic's ThreadX RTOS throughout the world. Under this new agreement, Express Logic's products will be integrated into Datang Mobile's UE (User Equipment) solution for 3G wireless phone equipment where ThreadX would be used to manage the software that controls RF communications between the phone and network base stations.

"We are pleased to offer our customers the highest performance, lowest cost products in wireless phone equipment," said Yuwang Sun, vice president of Datang Mobile. "Express Logic's ThreadX RTOS enables us to meet our demanding cost and performance goals and to pass these benefits along to our customers."

"We are proud to be working with Datang Mobile, a true leader in the Chinese telecommunications industry," said William E. Lamie, CEO of Express Logic. "This agreement provides us with an excellent channel for growth in China and confirms that Express Logic has the leading technological solutions and expertise that communications equipment manufacturers need."

Express Logic's ThreadX RTOS is a small, fast, royalty-free operating system ideal for high-volume consumer devices where high reliability and low cost are paramount. ThreadX provides advanced technology to manage application software with extreme efficiency. ThreadX resides in under 10KB of ROM, enabling it to fit on-chip advanced SoC designs. This small footprint saves cost and power, while also reducing overhead and extending battery life in portable devices.
