Dynamic Partial Reconfiguration (DPR) is a technique used in field-programmable gate arrays (FPGAs) that allows specific sections of the hardware to be reconfigured while the rest of the system continues to operate. This capability enables designers to update or change functionalities without interrupting the overall performance, making it ideal for applications requiring flexibility and adaptability. DPR is particularly useful in systems that need to switch between different tasks or algorithms on-the-fly, such as in telecommunications or signal processing. By utilizing DPR, developers can optimize resource usage and improve system efficiency, as only the necessary parts of the FPGA are modified as needed.
