The MB86R12 'Emerald-P' SoC is the latest addition to the Emerald device family. Its essential key feature is its Inova Semiconductor's highspeed APIX2® (Automotive/Advanced Pixel Link) interface, which is a high speed link for serial point-to-point connections for cameras and displays in a vehicle. APIX 2.0 functionality has therefore been incorporated in the Video Capture and Display Control units. The CPU core of MB86R12 'Emerald-P' is clocked at 533MHz.
MB86R12 'Emerald-P' combines the high-performance Cortex™-A9 CPU with four video inputs and up to three display outputs, enabling the high-speed image processing of video data I/O from these interfaces. For example, MB86R12 has made it possible using a single chip to develop a 360 degree wrap-around view system that synthesizes and converts a composite image of the surroundings of a vehicle in real time from the images of four cameras mounted on the front, rear, left and right of the vehicle. A function that automatically corrects the image contrast ensures high visibility at night or when employing the screen’s backlight. In addition, this function makes it possible to correct the image of TV or DVD video, making it crisp and bright. When displaying 3D maps in a car navigation system, graphics of not only intersections – which can already be displayed in high quality using existing systems – but also streets and scenery, can be displayed using higher-resolution textures.

Four Built-In Video Capture Functions: The four video input ports enable simultaneous processing of various different video images. The input function of up to 1,280 x 720 pixels, along with the enlargement/ reduction function and the function for converting moving images from interlaced format to progressive format, combine to enable the generation of images with minimal noise.
Three Output Display Functions and High-Speed 2D/3D Rendering Functions: It is equipped with three display controllers, two of which can multiplex and output two screens each, thereby accommodating up to five display outputs. With 8 display levels and an interlayer blending function, the outline of overlaid images on a background map screen dissolves, enabling images to blend into their surroundings. In addition, the ‘dither’ and ‘gamma correction’ functions enable high-quality images on displays with different resolution levels and colour properties. The built-in programmable-shader accurately renders light reflections and shadows, resulting in highly textured and life-like graphics images.
Built-In Image Enhancement Circuit: A built-in dedicated video processing engine makes adjustments for edge enhancement, chromatic correction, backlighting, and enhances the contrast of night-time footage, resulting in higher-quality video images. In addition, because backlight brightness is dynamically adjusted in accordance with the video stream data, power consumption for the system is reduced.
