Celestial Semiconductor Licenses ARM Processor To Meet Strong Demand For Next-Generation TV Standards

ARM technologies will enable designers to speed development of AVS-based chipsets for next-generation HDTV, DTV and STB offerings

BEIJING, CHINA AND CAMBRIDGE, UK - Apr. 25, 2005 - Celestial Semiconductor (Celestial), a fast growing company focusing on delivering solutions for the Chinese AVS standard, and ARM [(LSE: ARM); (Nasdaq: ARMHY)] today announced that Celestial has licensed a full range of ARM® technologies for its system-on-chip (SoC) solutions for televisions: the  processor, the Embedded Trace Macrocell™ (ETM9™) on-chip debug peripheral and the ARM® PrimeCell® Smart Card Interface (PL131). Combined, these technologies will enable Celestial to easily and cost-efficiently develop next-generation ARM Powered® codec chipsets and media processors for the high growth home applications such as HDTV, DTV and STB, including the support of the Audio Video Coding Standard Working Group of China (AVS) standard.

 "As ARM is the most widely-used architecture, the  processor - with its strong Java performance and multimedia signal processing - is ideal for our codec chipset and media processor design," said Mr. Daniel Fu, founder and CTO of Celestial. "This agreement will help us significantly reduce our time-to-market in delivery of standard-compliant SoCs for applications such as HDTV, DTV and STB, enabling us to meet the strong consumer demand for these applications."

"Meeting the strong demand for SoC standards to serve the HDTV, DTV and STB markets is a tremendous challenge for consumer electronics designers," said Dr. Jun Tan, president of ARM China. "Through the ARM Foundry Program, we are able to provide Celestial with industry-leading technology and an unmatched level of resources through our ARM Connected Community, enabling the rapid development of AV codec chipsets to deliver a much richer television experience for consumers."
