Abstract
A method and system for identifying frequency and length of time of execution of serialization instructions in a pipeline of a processing system, the processing including at least one performance monitor counter (PMC) and at least one monitor mode control register (MMCR) to configure the operations of the at least PMCs, includes counting a number of instructions forcing serialization or logically requiring serialization of the pipeline during a predetermined sampling period. Further included are counting a number of additional cycles required to complete the instructions during the predetermined sampling period, and determining a loss of efficiency from the counted number of instructions and the counted number of additional cycles accumulated during the predetermined sampling period.
