The branch misprediction penalty is a major performance limiter and a major cause of wasted energy in high-performance processors. The diverge-merge processor reduces this penalty by dynamically predicating a wide range of hard-to-predict branches at runtime in an energy-efficient way that doesn't significantly increase hardware complexity or require major ISA changes.

Index Terms:

predication, dynamic predication, branch prediction, adaptivity, pipelining, instruction level parallelism, energy efficiency
