\"What<\/figure>\n\n\n\n

FPGAs (Field-Programmable Gate Arrays)<\/strong> are reconfigurable semiconductor devices designed for parallel digital logic processing<\/strong>, allowing engineers to implement custom hardware functions after manufacturing. Unlike CPUs or GPUs<\/a> that follow fixed instruction sets, an FPGA\u2019s logic can be configured using Hardware Description Languages (HDLs) such as Verilog<\/strong> or VHDL<\/strong>.<\/p>\n\n\n\n

They are widely used in 5G telecommunications, high-speed networking, avionics, industrial automation, edge AI, and real-time signal processing<\/strong>.<\/p>\n\n\n\n

\u25b6 What Is an FPGA?<\/h2>\n\n\n\n

An FPGA is an integrated circuit<\/strong> composed of configurable logic blocks (CLBs), programmable interconnects, I\/O blocks, embedded memory, and optional DSP slices or hardware accelerators. Engineers program the hardware behavior, enabling custom digital circuits<\/strong> optimized for performance, latency, and throughput.<\/p>\n\n\n\n

In other words:<\/p>\n\n\n\n
