Processor Handles Multiple Video Streams, Displays

Processor Handles Multiple Video Streams, Displays

A new graphics processor could make it easier for future automobiles to process video from back-up cameras, side-view cameras, DVD systems and navigation devices and then show the video on as many as four separate displays.

Known as the MB86298 "Ruby" graphics processor, the new chip combines display control technology with graphics processing in a way that's never been done before.

"Where Ruby stands out is in its ability to capture multiple video images and then drive multiple displays of different sizes and different resolutions," says Dan Landeck, senior strategic marketing manager for the Automotive Group at Fujitsu, creator of the new chip.

The new chip comes in response to growing demand from automakers to put more cameras in vehicles, along with three-dimensional navigation systems, DVD players, specialized instrument panels and even televisions. Some automakers have already implemented back-up cameras and side-view cameras and others are planning to introduce drowsy-driver cameras.

"With this chip, you could capture four images from around the perimeter of the car and then you could put those onto a mesh where you could see all four together," Landeck says. "Then, using the graphics engine, you could adjust the polygons, distort them and resize them to create different perspectives."

A key advantage of the new chip is that it enables engineers to manage multiple video sources and multiple displays without making a big dent in their power budgets. Because it's a single chip - rather than a GPU and separate display controller - it's able to handle complex graphics chores with just a 2.5W power draw.

"This is not just a graphics processor and it's not just a display controller," Landeck says. "It's both. And it gives our customers many, many more options in terms of how they can deliver images to their screens." For more information, go tohttp://designnews.hotims.com/27742-528.
