A brief introduction of the acronyms that are going to be used:
The design is built upon ADI's generic HDL reference design framework. Thus, this reference design is used to interface the GMSL technology by using the MIPI CSI-2 specification for high-speed data transmission, and I2C standard for control. An in-depth presentation and instructions about the HDL design framework in general, can be found in the ADI Reference Designs HDL User Guide.
The architecture of this reference design is composed of multiple Xilinx's multimedia IPs that have the following roles:
In order to build the HDL design the user has to go through the following steps:
As regards the design's IPs, this GMSL-based reference design contains multiple AMD-Xilinx-related multimedia IPs such as MIPI CSI-2 Rx Subsystem, Axi-Stream Switch, Axi-Stream Subset Converter and Video Framebuffer Write, all these ones being available free of charge using standard AMD-Xilinx's Vivado version.
