My CS8803DC project, daytripper analyzes and rewrites binaries to better take advantage of Intel's Loop Stream Detector.

Loop Stream Detector

  • Introduced in Conroe, improved in Nehalem
  • Located following instruction fetch in Conroe and decode in Nehalem
  • Caches 18 fetched instructions in Conroe, and 28 decoded μops in Nehalem
  • LSD.UOPS: performance counter providing the number of μops delivered by the LSD (introduced on Core i7)
