Reconfigurable systems are flexible computing architectures that can be modified or reconfigured to perform different tasks. They often use hardware components like Field-Programmable Gate Arrays (FPGAs) or Programmable Logic Devices (PLDs) to adapt to various applications, allowing for efficient processing and resource utilization. These systems are particularly useful in fields such as telecommunications, automotive, and aerospace, where requirements can change rapidly. By enabling hardware to be reprogrammed, reconfigurable systems can improve performance, reduce costs, and extend the lifespan of technology by adapting to new challenges and demands.
