Broadcom Acquires Alphamosaic Limited, a Leading Developer of Mobile Multimedia Processors for Cellular Phones

Alphamosaic's VideoCore® Technology Complements Broadcom's EDGE and WCDMA Products to Enable Rich Multimedia Handsets

IRVINE, Calif. and CAMBRIDGE, United Kingdom, Sep 20, 2004 /PRNewswire-FirstCall via COMTEX/ -- Broadcom Corporation (Nasdaq: BRCM), a leading provider of highly integrated semiconductor solutions enabling broadband communications, today announced that it has acquired privately-held Alphamosaic Limited, a leading developer of advanced mobile imaging, multimedia and 3D graphics technology optimized for use in cellphones and other mobile devices.

Mobile phones are emerging as the dominant converged platform for multimedia services, with wireless handsets serving as digital cameras, digital video recorders, gaming consoles, personal organizers and digital TV receivers. Analyst firm In-Stat/MDR predicts that approximately 318 million cellular phones sold in 2006 will include digital cameras or imaging technology and that the number will double to over 600 million by 2008, for a compound annual growth rate of 81.2% from 2004 to 2009. With the acquisition of Cambridge-based Alphamosaic and its VideoCore® technology, Broadcom has added an expertise and technology critical to satisfy the requirements of these next generation mobile devices.

Cellular carriers continue to offer new multimedia data services to increase average revenue per user, such as Video on Demand (VOD), video conferencing, digital TV, interactive gaming and music downloads, necessitating multimedia capable handsets as well as the adoption of higher data rate wireless technologies such as EDGE and WCDMA. Broadcom was first to demonstrate high-speed "four-slot" EDGE performance at greater than 200 Kbps and recently acquired Zyray Wireless Inc., a leading developer of WCDMA baseband co-processors, which enable up to 384 Kbps of wireless data connectivity. Alphamosaic® technology further strengthens the Broadcom® cellular product portfolio and enables Broadcom to provide complete reference designs for next generation, feature-rich multimedia mobile phone platforms.

"Broadcom currently provides cellular OEMs with EDGE/GPRS/GSM baseband processors as well as single-chip Bluetooth® and 802.11 solutions, and we are now sampling WCDMA baseband processors as well," said Robert A. Rango, Group Vice President of Broadcom's Mobile & Wireless Group. "Alphamosaic adds best-in-class multimedia capabilities to our product portfolio. Alphamosaic's products are offered as discrete co-processors and will also be integrated into Broadcom's cellular baseband and application processor roadmaps in the future to meet the emerging power, space and price requirements of converged multimedia handsets. Equally importantly, we have added another world class engineering team in Cambridge, with deep expertise in still image, video, graphics, audio, and related multimedia and processor technologies."

Alphamosaic's first-generation VC01 multimedia co-processor is currently being used by leading cellular handset makers such as Samsung. Commercially available Samsung phones now incorporate the VC01 for advanced multimedia functions including MP3 player, VOD, megapixel-class camera and digital camcorder. "The VC01 was what Samsung was looking for," one of Samsung Electronics' representatives stated. "VC01 provided the right set of features for high end video phones."

Building on the success of the VC01, Alphamosaic is now sampling VC02, the world's most advanced mobile multimedia processor. The VC02 can display video on 3.5 inch color LCDs and capture 8 megapixel images, making it ideal for watching TV, making videos or taking studio-quality photos on a cellphone.

"Broadcom's impressive wireless product portfolio is a perfect complement to our VideoCore products, strengthening the presence of both companies in worldwide cellular markets," said Dr. Jalal Bagherli, CEO of Alphamosaic Limited. "VideoCore technology was developed by the strong team at Alphamosaic to specifically enable high performance multimedia in cellular handsets, while maintaining the flexibility to migrate to new applications and emerging standards, and address carrier-specific requirements."

VideoCore Technology

Alphamosaic's VideoCore technology is rapidly establishing itself as the leading solution for low power, high performance multimedia processing in cellular phones and other mobile devices. It is a fully programmable, highly parallel architecture optimized for high performance applications while maintaining industry-leading low power operation. Competing solutions often use general purpose processors at high clock frequencies to achieve performance, resulting in higher power consumption. Additionally, those solutions require hardware accelerators for specific fixed functions which lack flexibility and scalability to support new emerging standards.

In a joint statement, Alphamosaic founders Steve Barlow (CTO) and Dr. Robert Swann (VP Marketing) said: "From our founding, we committed to develop a technology that would revolutionize multimedia in mobile handheld products. Since that time, we have delivered both production-proven technology and commercial success. With the strength and clear pathway that being part of Broadcom will provide, we look forward to furthering our vision and achieving even greater success."

The programmable nature of the VideoCore product family allows scaling to new video and audio standards such as H.264 and aacPlus. H.264 video compression will be important as broadcasters demand bandwidth-efficient compression schemes to deliver digital video to mobile devices. VideoCore also reduces overall system cost by integrating all image processing functionality, allowing connection directly to CMOS/CCD camera sensors and eliminating the need for a separate image processing chip. The VideoCore product family also excels in high-quality 3D graphics performance with the capability to support pixel shading and volumetric lighting with low power consumption, making it ideal for use in mobile gaming applications and comparable in performance to home consoles.

Broadcom and Cambridge

Alphamosaic's 57-person team augments Broadcom's existing technology group in Cambridge, which focuses on the development of digital signal processing architectures and compilers and embedded software. Cambridge, one of the world's leading research centers, is the heart of the UK high tech industry. The surrounding area, informally known as Silicon Fen, has become a center for European semiconductor operations.

Transaction Details

In connection with the acquisition, Broadcom issued or reserved for future issuance an aggregate of approximately 4.17 million shares of its Class A common stock (with a value of approximately $120.3 million based upon the NASDAQ National Market closing price on September 17th of $28.86 per share), and agreed to make cash payments aggregating approximately $2.7 million, in exchange for all outstanding shares of Alphamosaic capital stock and upon exercise of outstanding employee stock options of Alphamosaic. A portion of the shares issued will be subject to escrow pursuant to the terms of the acquisition agreement. Broadcom has also assumed obligations under a long term incentive plan that could result in the issuance of up to approximately 141,000 additional shares of Broadcom Class A common stock to Alphamosaic employees. Broadcom acquired approximately 93% of the fully-diluted equity ownership of Alphamosaic at a first closing on September 17th and anticipates acquiring the remaining capital stock at a second closing to occur in approximately 10 days. Following the second closing, Broadcom will file a registration statement on Form S-3 with the Securities and Exchange Commission to register the shares issued for resale in the United States. Broadcom may record a one-time charge for purchased in-process research and development expenses related to the acquisition in its third fiscal quarter, ending September 30. The amount of that charge, if any, has not yet been determined.
