18.3.2 Video capture function

• This device has two video input ports

• One video input port supports both ITU RBT-656 and RGB666, the other supports RGB666 only

• Video data is stored in graphics memory and later displayed on the screen in synchronization with

the display scan

• A upscale factor of 1 to 2 can be used. PAL or NTSC images can be displayed on a wide screen

• A downscale factor of 1 to 1/32 can be used

• Picture-in-picture can be used to display drawn images and video images on the same screen

The MB86R02 'Jade-D' has a geometry engine for performing the numerical operations required for

intensive graphics processing. The geometry engine uses the floating-point format for highly precise

operations. It selects the required geometry processing according to the configured drawing mode and

primitive type and executes processing for the final drawing.

Point, line, line strip, independent triangle, triangle strip, triangle fan and arbitrary polygon are

MVP Transformation

A 4 × 4 transformation matrix enables the transformation of a 3D model view projection. Two-

dimensional affine transformation is also possible.

Clipping stops the drawing of objects outside the window (field of view). Polygons (including

concave shapes) can also be clipped.

Rear-facing triangles are not drawn.

3D-2D Transformation

These functions transform 3D coordinates (normalization) into 2D coordinates in orthogonal or

perspective projections.

View port transformation

This function transforms normalized 2D coordinates into drawing (device) coordinates.

Primitive setup

This function automatically performs a variety of slope computations, etc., based on transforming

vertex data into coordinates and prepares for rendering (setup).

Log output of device coordinates

The view port conversion results are output to the local memory.
