Several recent architectural proposals, including TRIPS and WaveScalar, advocate dataflow-like architectures as a good match for the execution substrates projected in the next decade and beyond.   In this program, Doug Burger discusses the future of architecture research, describing the TRIPS prototype architecture and a distributed selective re-execution protocol. His special focus is describing a scheme which provides a unified underlying framework to aid recovery from mis-speculation and soft errors. From the Series:CSE Colloquia - 2004
