Peter was appointed as the chairman of the Hong Kong Programming Society for 2023-2025. The document discusses field-programmable gate arrays (FPGAs), which are programmable logic devices that can be reconfigured after manufacturing. It also covers the basic components of FPGAs, including logic elements and configurable logic blocks, as well as how lookup tables (LUTs) work and the process of technology mapping to different programmable devices like ASICs, PALs, and FPGAs.
