DECADES-OLD EXPLICIT DATAFLOW ARCHITECTURES ELIMINATE MANY OF THE OVERHEADS OF GENERAL-PURPOSE PROCESSORS BUT HAVE NOT BEEN SUCCESSFUL BECAUSE OF THEIR LACK OF SUFFICIENT CONTROL SPECULATION AND THE LATENCY OVERHEAD OF EXPLICIT COMMUNICATION. THIS ARTICLE OBSERVES A SYNERGY BETWEEN OUT-OF-ORDER AND EXPLICIT DATAFLOW PROCESSORS, IN WHICH DYNAMICALLY SWITCHING BETWEEN THEM ACCORDING TO PROGRAM PHASES CAN GREATLY IMPROVE PERFORMANCE AND ENERGY EFFICIENCY.
