  1. Can we design a core that adaptsto the thread-level parallelism in programs? MorphCore High performance and energy-efficiency on bothsingle- and multi-threaded programs

  2. MorphCore The opposite of previous proposals: A) The base design: OOO core B) Then we add in-order SMT Two modes: out-of-order core Exploits ILP High single-thread performance OutOfOrder highly-threaded in-order SMT core Exploits TLP High multi-thread performance No OOO execution  Energy savings InOrder

  3. By requiring minimal changes to a traditional OOO core • 2- and 4-way SMT large OOO cores • Medium OOO cores • Small in-order cores • And Core Fusion MorphCore outperforms

  4. MorphCore: An Energy-Efficient Architecture for High-Performance ILP and High-Throughput TLP Khubaib M. AaterSulemanMiladHashemi Chris Wilkerson Yale N. Patt The University of Texas at Austin Tuesday at 13:30 in Section 5A “Core Design”
