LINEO RELEASES LINEO uLinux CE EDITION BSP FOR
RENESAS SH4 2D GRAPHICS REFERENCE BOARD
- Hard Realtime with Linux Implemented -

TOKYO, December 2, 2003 - Lineo Solutions, Inc. (Lineo), a leading provider of embedded Linux solutions, today announced the release of Lineo uLinux Consumer Electronics Edition (CE Edition) Board Support Package (BSP) for Renesas Technology's SH4 2D Graphics reference board (RTS7751R2D).

"The SH4 2D Graphics reference board is fully equipped with such actual application oriented hardware as 2D Video Engine, 12" SVGA LCD with Touch Panel, 100BASE/T LAN Port x 2, and etc.," said Akira Kobayashi, Executive Director, Engineering, Lineo Solutions, Inc. "Together with kernel XIP (Execute in Place) and Hard Real Time support in the kernel space by reliable and high-performance uLinux CE Edition, the BSP released this time, I believe, will expand the scope of the embedded Linux device applications for the engineer at the product development site of the set maker in Ubiquitous Network Age."

"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, the increasing number of the product developer tends 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. "In order to develop a product within limited time frame without failure, the availability of 'pre-tested source code' with those functionalities will have indispensable values. And I expect Lineo uLinux CE Edition that is pre-tested on Renesas SH4-Graphics Platform (RTS7751R2D) will contribute in accelerating the product development in a great extent."

The BSP is provided as a plug-in for Lineo "uLinux ELITE" (ELITE), Lineo's embedded Linux cross development environment.
