Fujitsu Microelectronics America Inc. has introduced its 3D, 64-bit, 200MHz Coral graphic display controller that is suitable for delivering in-vehicle display applications such as map creation and video displays.

"This graphic display controller gives auto OEMs the ability to display various images in PC-like windows," said Dan Landeck, FMA senior marketing manager. "Coral also can re-size inputs for easier viewing. Auto manufacturers and their customers can use these powerful new capabilities for navigational and video entertainment applications."

The controller provides support for six layers, and incorporates a multiple geometry engine and enhanced video input capabilities. Coral supports conventional XGA display, a 4-layer overlay, left/right picture display, wraparound scrolling, double buffers, and translucent display. The 6-display layer supports four different color palettes, each with 256 colors. All layers offer 24- or 16-bit resolution with direct color or 8-bit resolution, indirect color.

Coral operates similarly to the Windows OS, allowing graphic inputs to be doubled in size, and the windows display-layer management functions can deliver several images simultaneously. This video-input upscaling capability makes possible the display of high-resolution, full-screen-mode multimedia pictures. Upscaling and downscaling can be set independently in horizontal and vertical directions in pixel or line resolutions.

Enhanced bandwidth

The 200MHz internal frequency reaches 400MHz for display dot clocks, which enables its rendering engine to achieve an order of magnitude improvement in texture mapping and drawing image quality over previous graphic display controller products.

The enhanced bandwidth allows a faster access rate for graphic elements, such as polygons, and also delivers improved scanning functions within the display controller. It also provides powerful alpha mapping, which enables alpha blending to allow each screen element to be viewed at different levels of transparency.

The device also integrates a line-depth display capability, which enhances 2D drawing functions by clearly defining the intersecting map lines. Coral can address up to 64MB of external SDRAM or the company's FCRAM device.

The external video input of Coral conforms to the RBT-ITU656 (YUV4: 2:2 format) standard to allow video signals to be displayed together with generated graphic. The video input can accept TV tuner, DVD player or camera signals in PAL or NTSC video formats.

Coral uses approximately 1.5W and is compatible with all of Fujitsu's graphic display controller ICs. It requires no external glue logic and is available in either BGA or QFP packages. The Coral is priced at $32 each in 10,000-unit quantities.
