[Serialization] FPGA-based instance of the Tilde-HDL series-data selector

[Serialization] FPGA OpenGL series instances

Data Selector Based on OpenGL

I. Principles

Data selection refers to transferring data from multiple channels to the unique public data channel after selection. The logical circuit that enables data selection is called a data selector. It acts as a single-knife, multi-Throw Switch with multiple inputs.
