Working Principles

FPGAs consist of an array of configurable logic blocks interconnected through programmable routing resources. These logic blocks contain Look-Up Tables (LUTs), flip-flops, and other components that can be configured to implement desired logic functions. The interconnections between these blocks can be programmed to establish desired data paths.

During operation, the FPGA is programmed with a bitstream that configures the logic blocks and interconnections. The programmed logic then performs the desired functions, executing tasks based on the input signals and internal configuration.
