Run-time Reconfigurable ``RTR'' Logic

Run-time reconfigurable systems are used to get best performance with maximum hardware utilization. The circuits are loaded into the hardware and unloaded from it dynamically during the operation of the system. So the area used by such systems will be less than static systems due to unloading idle circuits. RTR systems can be built on single FPGA chip or on multi-IC systems like CCMs. The flow of operation of RTR systems is different from the traditional flow of the general computing systems, where as the circuits configurations are loaded into the system's memory instead of the traditional instructions. These configurations are loaded and unloaded according to the application needs. Refer to figure 1 for a small comparison between different systems.
