A reconfigurable computer includes a reconfigurable processing element configured to process raw payload data in accordance with a configuration that is applied to the reconfigurable processing element. The reconfigurable computer further includes a multi-port communication device comprising a first port at which at least a portion of the raw payload data is written to the multi-port communication device and a second port at which at least a portion raw payload data written to the multi-port communication device is read by the reconfigurable processing element. The reconfigurable computer further includes a controller coupled to the reconfigurable processing element. The controller applies the configuration to the reconfigurable processing element and wherein the controller performs at least one single event upset mitigation operation.
