- * High level "TopDown" CPU core pipe line bottleneck break down.
- *
- * Basic concept following
- * Yasin, A Top Down Method for Performance analysis and Counter architecture
- * ISPASS14
- *
- * The CPU pipeline is divided into 4 areas that can be bottlenecks:
- *
- * Frontend -> Backend -> Retiring
- * BadSpeculation in addition means out of order execution that is thrown away
- * (for example branch mispredictions)
- * Frontend is instruction decoding.
- * Backend is execution, like computation and accessing data in memory
- * Retiring is good execution that is not directly bottlenecked
- *
- * The formulas are computed in slots.
- * A slot is an entry in the pipeline each for the pipeline width
- * (for example a 4-wide pipeline has 4 slots for each cycle)
- *
- * Formulas:
- * BadSpeculation = ((SlotsIssued - SlotsRetired) + RecoveryBubbles) /
- * TotalSlots
- * Retiring = SlotsRetired / TotalSlots
- * FrontendBound = FetchBubbles / TotalSlots
- * BackendBound = 1.0 - BadSpeculation - Retiring - FrontendBound
- *
- * The kernel provides the mapping to the low level CPU events and any scaling
- * needed for the CPU pipeline width, for example:
- *
- * TotalSlots = Cycles * 4
