    • HotPlug support

Lineo lists the following features for Renesas Technology SH4 2D Graphics Board (RTS7751R2D):

• SH7751R (240/267 MHz), 64M SD-RAM, card-BUS, 2 PCI slot
  • FSB 120/133 MHz
  • FPGA (Lo-speed BUS split/True IDE/Touch Panel)

• Silicon Motion SM501 (Voyager GX)
  • Embedded 2D video engine supporting 7-layered H/W frame
  • Dual display support (analog CRT, digital LCD)
  • I/O expansion for SH-4 CPU (USB host, AC97, I2S, I2C, ZV, GPIO)
  • Digital Video input 'YUV 4.2.2'
  • Lo power consumption (75mW @2D engine enable)

• SD memory card support
• 100 BASE/T LAN (2ch)
• SH-BUS expansion for support external decoder logics
• 12-inch SVGA TFT LCD — w/touch panel, AC97 codec (AD1885)
• Debugger I/F (AUD, H-UDI)

“The SH4 2D Graphics reference board is fully equipped with such actual application oriented hardware as 2D Video Engine, 12-inch SVGA LCD with Touch Panel, 100BASE/T LAN Port x 2, and more,” said Akira Kobayashi, Executive Director, Engineering, Lineo Solutions, Inc.

“There are increasing demands to use Linux for digital consumer products with LCD supporting GUI operation with touch panel, audio/video playback, etc. In those products, an increasing number of the product developers tend to adopt embedded Linux that supports Realtime response and quick boot/shutoff capability because operability without being conscious of OS is crucial,” said Hisao Munakata, Senior Engineer, Corporate Business Strategy, Planning & Marketing Div., Renesas Technology Corp.
