Reconfigurable computing is a technology that allows hardware to be modified or reconfigured to perform different tasks. This flexibility enables systems to adapt to various applications, improving performance and efficiency. It often uses devices like Field-Programmable Gate Arrays (FPGAs) that can be programmed after manufacturing to suit specific needs. By changing the configuration of the hardware, reconfigurable computing can optimize processing for tasks such as signal processing, machine learning, or data encryption. This adaptability makes it a valuable approach in fields where requirements frequently change, allowing for faster and more efficient computing solutions.
