The Video Mixer provides a flexible video processing block for alpha blending and compositing multiple video and/or graphics layers.

Support for up to seventeen layers (one main layer and sixteen overlay layers), with an optional logo layer, using a combination of video inputs from either memory or streaming video cores (through AXI4-Stream interfaces) is provided.

The core is programmable through a comprehensive register interface to control frame size, background color, layer position, and the AXI4-Lite interface. A comprehensive set of interrupt status bits is provided for processor monitoring

Features

• Supports (per pixel) alpha-blending of seventeen video/graphics and logo layers video/graphics

• Optional logo (in block RAM) layer with color transparency support

• Layers can either be memory mapped AXI4 interface or AXI4-Stream

• Provides programmable background color

• Provides programmable layer position and size

• Provides upscaling of layers by 1x, 2x, or 4x

• Optional built-in color space conversion and chroma re-sampling

• Supports RGB, YUV 444, YUV 422, YUV 420

• Supports 8, 10, 12, and 16 bits per color component input and output on stream interface, 8-bit and 10-bit per color component on memory interface

• Supports semi-planar memory formats next to packed memory formats

• Supports spatial resolutions from 64 × 64 up to 8,192 × 4,320

• Supports 8K60 in all supported device families

• Supports Programmable CSC coefficients to support various calorimetry like BT601, BT709 and BT2020.

• Supports 1, 2, 4, or 8 samples per clock.

• Supports programmable CSC coefficient registers .

Creation of new project suitable for MiniZed board with XC7Z007S-1CLG225C Device:

Select Xc7Z007sclg225-1 device as it is available on MiniZed board

Click on Create block design

Select Video Mixer and add the Core

Right click on the block and select "Customize the block". Select the following parameters:

Add the different IP interfaces as shown in below figure:

Video Test pattern generator block is added as shown:

The video timing controller and AXI4 stream to Video out blocks are added:

The simulation for the whole setup can be performed by clicking on the Run Simulation

Click on Run Implementation:

Connect the MiniZed board to the PC using USB JTAG UART port and start the Vivado ILA to check for the waveforms from the Core.
