    Hi dmazuelos,

    Thanks for your reply.

    As to the second question: how to know the stall cycles for e.g. icache miss?  Take event 0x001 (Level 1 instruction cache refill) as example, can I know the percentage of event 0x001 within one time duration (for example 5s)? Or can I know how many cycles are occupied by event 0x001 with that time duration?

    Thanks.
