SUNNYVALE, Calif., June 13  -- Silicon Image, Inc., a leader in multi-gigabit semiconductor solutions for the secure transmission and storage of rich digital media, today announced that it ranked among the Top 10 in Gartner, Inc.'s recently published 2004 Semiconductor Intellectual Property (IP) Survey(1). With $20.8 million in IP revenue for 2004, Silicon Image debuted at number 10 among 135 semiconductor IP vendors as ranked by total worldwide revenue for 2004. Silicon Image also ranked number 10 according to total royalty revenue worldwide for 2004 and was the second largest vendor of wired interface blocks.

According to the Gartner report, the semiconductor IP market posted growth of 21 percent in 2004, with the market expected to grow faster than the overall semiconductor market during the next five years.

Silicon Image's IP encompasses High Definition Multimedia Interface (HDMI), Digital Video Interface (DVI) and Serial ATA (SATA). Silicon Image developed the world's first DVI and HDMI chips and is the leading provider of HDMI and SATA semiconductors. The company has shipped more than 80 million PanelLink HDMI and DVI ICs and over seven million SATA ICs. Silicon Image is also the primary author of the HDMI Compliance Test Specification and operates one of the world's three HDMI Authorized Testing Centers, as well as the industry's only DVI Compliance Test Center(TM).

"System-on-chip (SoC) designers and ASIC vendors like Samsung, MediaTek, ATI, Micronas, Sunplus and Trident demand silicon-proven, compliance-verified and fully supported IP so that they can produce devices that work the first time," stated Eric Almgren, Silicon Image vice president of business development and IP licensing. "Silicon Image delivers high-quality IP backed by a strong engineering support team, which has enabled us to become a Top 10 IP provider in three short years."

Silicon Image offers HDMI transmitter and receiver core IP, including the digital logic and analog PHY. Silicon Image's HDMI cores are compliant with the HDMI 1.1 specification and have undergone extensive verification testing. Silicon Image's HDMI technology includes High-bandwidth Digital Content Protection (HDCP), supported by Hollywood as the technology of choice for the distribution of premium digital content. HDMI receiver core IP is ideal for DTVs and HDTVs, including LCDs, DLPs, plasma TVs and high-end CRTs, as well as projectors and A/V receivers. Silicon Image HDMI receiver core IP provides full support for HDCP decryption and authentication. Silicon Image's DVI cores are DVI-compliant and support the full DVI bandwidth of 25 to 165 MHz. In addition, the company also offers SATA host- and device-side core IP, including the Transport, Link and PHY layers with PCI, PCI-X or AMBA SoC internal interface options.
