描述 Description

MB86291 is an enhanced version of MB86290A \"Cremson\" which adds 16Mbit embedded SDRAM, video input functions and a geometry processor. The concept of display layers, 2D/3D rendering functions and the display controller features are taken from \"Cremson\" MB86290A. Scarlet is optimized for applications in car navigation systems which requires video input features, consumer information processing systems and arcade game applications.

Scarlet has 16 Mbit of embedded SDRAM with high bandwidth (100MHz). No external SDRAM devices are required for graphic memory. The external video input can be used to capture video signals according to the standard RBT-ITU656 YUV4:2:2 format. Picture-in-picture functions are supported to display the video image (the W-layer is dedicated for that purpose). To adjust the dimensions of the video input format, a flexible video scaler is integrated.

A geometry processor, capable of performing numeric calculations for graphical operations is included. Supported functions are Affin-conversions, model-view-projections, 3D-clipping operations and others. All drawing functions, display list-formats and software functions are compatible to the \"Cremson\" MB86290A. An additional RGB digital interface offers flexible display connections.
