A Method for Guaranteeing Timing Precision for Randomly Arriving Asynchronous Events

摘要

The timing stream is used to capture pipeline advances and to record stall cycles. Timing streams may be in standard or compressed formats. The stalls are traced concurrently with the PC trace. The data trace is used for holding the reasons for the external event. The timing stream also holds external event information, to assure cycle accuracy of the event being traced.
