Cyclone IV reconfiguration

No, i meant run-time reconfiguration. Specifically, i want to implement a learning model on an FPGA in such a way that when the model will change its parameters, the FPGA will reconfigure itself accordingly. According to the Altera pdf (i cannot post links, so just google "software programmable reconfiguration" and click the first link) this reconfiguration should be controlled by the NIOS II embedded processor.
