Fujitsu Microelectronics America Inc. (FMA) has unveiled the latest member of its family of automotive apps" target=_blank>graphics display controllers (GDCs) for vehicle navigation systems. The MB86297 is designed for high-end vehicle multimedia and virtual dashboard applications.

The MB86297 GDC is built with a high-performance graphics core that delivers more than five times the performance provided by its predecessor, the MB86296 GDC. The new GDC is specifically designed for the latest generation of automotive information/entertainment systems, including head-end units and fully configurable instrument clusters that require high quality and versatile human-machine interfaces.

Realistic 3D effects
MB86297 supports all 2D functions, 3D functions, and fogging and lighting to provide dramatic and realistic 3D effects. The GDC enables point-of-view and bird's eye navigation to be rendered very rapidly, while producing images that match those available with desktop graphics. The maximum power consumption of the MB86297 is under 2.3W, far below other GDC products of similar performance.

"The MB86297 is the most advanced GDC designed for automotive applications, with layering, blending, video capture, dual monitor support, and drawing performance at up to 10 million polygons per second," said Dan Landeck, senior marketing manager for GDC products at FMA's embedded systems solutions business group.

Because the MB86297 is compatible with OpenGL ES 1.1, it makes software development a relatively hardware-independent task. Hardware support for OpenGL ES presents developers with a familiar, highly standardized software development pathway, and helps ensure future code portability. Fujitsu will provide customers with an OpenGL API and low-level access library to assist the software development effort.

The MB86297 incorporates two digital RGB display output channels with resolutions ranging from 320-by-240 up to 1280-by-1024. Several intermediate resolutions are also available. Unlike other dual-monitor GDCs, the MB86297 will drive two displays that have two different resolutions, such as a head- end display and an information display located in or around the instrument cluster.

Alpha-plane function
For each output display channel, eight layers support alpha blending where a transparency value is applied evenly to the entire layer. Four of the layers are designated as alpha planes, enabling transparency at the pixel level. The alpha-plane function lets users create special effects such as spot lighting on maps, and the ability to zoom in and out of icons or menus to and from lower layers.

The MB86297 also supports two independent video capture ports for YUV/ RGB input. The GDC will perform various operations on the video including up/down scaling, and brightness, contrast and saturation control. All the I/O ports are independent, non-multiplexed, which means no pins are shared, enabling all features to be used simultaneously.

The MB86297 is manufactured using Fujitsu's 90nm process, and comes in a 543-pin TEBGA package. Prices start at $30 each in one 100,000-unit volumes.
