A new configuration scheduling algorithm in multicast configuration scheme is proposed and evaluated over reduction ratio of configuration data transfer cycles and powerlenergy overhead on a coarse-grained dynamically reconfigurable processor array (DRPA). As a case study, the proposed methods are applied to some real applications on a DRPA architecture MuCCRA-1. As a result, we confirmed that the proposed overwrite configuration technique for DRPAs reduced an application configuration cycles 66.5% at maximum compared to one without multicast and 20.2% compared to one without the overwrite configuration. It also decreased the configuration energy consumption 18. 7% at maximum beyond the overhead of memory overwrites.
