Effects of Pipeline Complexity on SMT / CMP Power-Performance Efficiency

  title={Effects of Pipeline Complexity on SMT / CMP Power-Performance Efficiency},
  author={Benjamin C. Lee and David M. Brooks},
We consider processor core complexity and its implications for the power-performance efficiency of SMT and CMP architectures, exploring fundamental trade-offs between the efficiency of multi-core architectures and the complexity of their cores from a power-performance perspective. Taking pipeline depth and width as proxies for core complexity, we conduct power-performance simulations of several SMT and CMP architectures employing cores of varying complexity. Our analyses identify efficient… CONTINUE READING
