Graphics controller offers high-speed rendering

A novel high-performance single-chip image processor offers display resolution up to 38Mpixel/s and 2048 x 2048pixel and supports displays from quarter-VGA or smaller up to SVGA.

A novel high-performance single-chip image processor offers display resolution up to 38Mpixel/s and 2048 x 2048pixel and supports displays from quarter-VGA (320 x 240) or smaller, up to SVGA (800 x 600).

The fast drawing capabilities of the Ravin-E from NEC Electronics (Europe) make it suitable for a variety of multimedia applications including in-car navigation, dashboard displays, GPS systems and webphones.

Ravin-E is being launched especially for the European market.

Ravin-E transfers bitmapped colour graphics data from a 64Mbyte frame buffer memory via a 32bit SDRAM interface to a display (usually a TFT or CRT) and generates the necessary control signals.

Ravin-E is the ideal partner to support MIPS-RISC processors such as NEC's VRs in handling data for fine-resolution, high-information content images as used in today's multimedia applications.

For example, the fast rendering capabilities of Ravin-E enable smooth scrolling of high-definition maps for in-car navigation systems.

With its built-in graphics accelerator, Ravin-E is capable of drawing up to 2.5 million lines (of 10pixel each) or 150,000 polygons each second.

It supports alphablending and antialiasing and is also able to overlay graphics with full-speed video which can be easily scaled on-screen.

This means it is easy to enable video input whether from a TV, DVD or even an in-car camera.

Ravin-E is suitable for operating temperatures from -40 to +85C and is supplied in a 240-pin FPBGA package.
