Original Abstract Submitted
Systems and methods are described to collect latency data of transactions traversing a processor using a performance monitor, which uses a bucket timer based on a granule value in a configurable granule counter. The monitor can determine a transaction time for a transaction, which can then be compared to enumerated buckets (where the bucket size is based on the granule value), determine the appropriate bucket, and increment a latency counter associated with the bucket. The monitor can include a saturation mechanism to account for overflow or saturation. The collected data can be read by an external device to generate a histogram to identify potential problems in the processor or processor pipeline.
