Configuration with Self-configured Data Path (CSDP) is a high speed configuration data loading method for Dynamically Reconfigurable Processors (DRPs). By using a prepared configuration data, a network for computation in DRPs can be used as a configuration data path when the computation is stalled and the controller requires the configuration data transfer. Design and implementation of a DRP called MuCCRA-3.32b with CSDP demonstrates that the time for computation can be reduced to a half with only
