Video Mixer on XC7Z007S-1CLG225C device on MiniZed Board

  • Content can be placed in blog layout instead of comment section. 

  • 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 .
