Reconfigurable processors utilize a reconfigurable fabric and may perform runtime reconfigurations to exchange the set of deployed accelerators during application execution. Depending on the application requirements, the high utilization of the reconfigurable fabric leads to a performance improvement compared to non-reconfigurable Application Specific Instructions-set Processor (ASIPs). However, as the reconfiguration time of fine-grained reconfigurable fabrics is rather long, it is crucial to avoid frequent cycles of reconfiguration-replacement-reconfiguration of the accelerators in order to exploit the real benefits of reconfigurable processors.
