Dynamic reconfiguration

Definition

Dynamic reconfiguration refers to the ability of a computing system, particularly those utilizing FPGAs (Field Programmable Gate Arrays), to change its configuration or functionality on-the-fly without needing to power down or interrupt its operation. This allows for greater flexibility and adaptability in processing tasks as it can adjust its hardware setup to meet varying computational demands in real time.
