“…Reference [3] also describes the 604 PM, including specific examples related to event sampling, thresholding, and symmetric multiprocessor (SMP) analysis. Reference [4] shows how the 604 PM can be used to examine and contrast the effects of hardware variations on system performance, while Reference [5] describes the intended use of the 604e PM and provides some additional insight into items mentioned in this paper.…”

Performance monitor (PM) support in on-ciiipPowerPC® microprocessors is used to analyze processor, software, and system attributes for a variety of worlcloads. The interface to the PowerPC 604® microprocessor, which we abbreviate "604," has been externalized to end users. We discuss the enhanced PM support available in an upgrade of the 604, the PowerPC 604e™ microprocessor, which we abbreviate "604e." We discuss the challenges related to the externalization of the PM support as it relates to other PowerPC processors not derived from the 604 and briefly contrast these PMs with other PMs. We also describe an application programming interface (API) to the on-chip PM support, its design methodology, and its usage considerations, intended to meet these challenges.
