Silicon Image HDMI and Serial ATA Core IP Available in State-of-the-Art Process Technologies

Drives Integration Into Leading Manufacturers' SOCs

SUNNYVALE, Calif., February 28, 2005—Silicon Image, Inc. (Nasdaq: SIMG), a leader in multi-gigabit semiconductor solutions for the secure transmission and storage of rich digital media, today launched High-Definition Multimedia Interface™ (HDMI)™ and Serial ATA (SATA) core intellectual property (IP) for integration into the latest system-on-chip (SoC) technologies.  Silicon Image has ported its SATALink™ SATA core to multiple 90nm and 0.13-micron foundry processes and is currently porting its PanelLink^® HDMI core to 0.13-micron foundry processes-allowing licensing customers to integrate the most advanced SATA and HDMI functionality in their market-leading SoC implementations. 

"Not only is Silicon Image a leader in HDMI, DVI and SATA semiconductors with more than 100 million chips shipped, but we are also a leading provider of mixed-signal core IP," said Eric Almgren, Silicon Image vice president of business development and IP licensing.  "Our new HDMI and SATA IP offerings demonstrate Silicon Image's commitment to providing customers with state-of-the-art, silicon-proven technology.  By integrating the latest core IP, our customers are able to reduce overall system costs and accelerate the introduction of new products to market, helping them remain competitive."

Licensing core IP from Silicon Image has many benefits.  Silicon Image's silicon-proven IP enables customers to achieve quicker time-to-market through shorter design cycles, with lower implementation risk and faster compliance testing.  IP customers can also achieve lower costs by allocating fewer engineering resources and reducing the number of passes through the fab, while facilitating higher levels of chip integration.  Silicon Image's expertise in the development, manufacture and testing of SATA and HDMI mixed-signal products provides IP customers with the confidence they need to develop integrated semiconductor solutions on a timely basis.

Silicon Image developed the world's first DVI and HDMI chips and is the leading provider of HDMI semiconductors.  The company has shipped more than 80 million PanelLink HDMI and DVI ICs.  Silicon Image is also the primary author of the HDMI Compliance Test Specification and operates one of the world's two HDMI Authorized Testing Centers.  Silicon Image's PanelLink HDMI transmitter and receiver IP cores are compliant with the HDMI 1.1 specification and are ideal for DVD players and recorders, set-top boxes, A/V receivers, digital TVs (plasma, LCD, DLP) and projectors. 

Silicon Image is also the leading provider of discrete SATA host controllers with more than six million shipped to date.  Silicon Image offers silicon-proven SATA host- and device-side core IP for integration into customers' SoCs used in applications such as DVD recorders, set-top-boxes, optical drives, TVs, storage servers and sophisticated RAID storage systems.  Silicon Image SATA IP cores support 1.5 and 3.0 Gb/s data transfer rates and advanced SATA features such as hot plug, Native Command Queuing, port multipliers with Frame Information Structure (FIS)-based switching and extended cable lengths, as well as sophisticated RAID capabilities. 

SATA host-side core IP includes the Transport, Link and PHY layers with PCI, PCI-X or AMBA SoC internal interface options.  Device-side SATA core IP combines the Transport, Link and PHY layers with parallel ATA or AMBA SOC internal interface options.  The SATA host and device cores may be licensed as a single block or as separate PHY and Link/Transport blocks. Silicon Image also licenses PCI Express and Fibre Channel core IP as well as high-speed SerDes (Serializer/Deserializer) PHY technology.

Silicon Image has licensed IP to ATI, MediaTek, Novatek, Samsung, Sunplus, Trident and Weltrend, as well as many other leading SoC manufacturers worldwide.  Silicon Image's HDMI, SATA and DVI cores have been designed and tested for production at TSMC, UMC and other foundries using various 0.18-micron, 0.13-micron and 90nm process technologies.  Upon request, Silicon Image can port core IP to other foundries and process technologies to meet licensees' production needs. 

Silicon Image will be exhibiting at booth number 2443 during the Embedded Systems Conference, which is being held March 8-10 at Moscone Center in San Francisco.  Information on Silicon Image's core licensing program can be found on the Silicon Image website at www.siliconimage.com.  To license Silicon Image's market-leading IP, please contact s_cores@siliconimage.com
