摘要:
A bus monitoring and debugging system operating independently without impacting the normal operation of the CPU and without adding any overhead to the application being monitored. Bus transactions to a selected slave are monitored to determine possible conflicts when multiple masters may be addressing the slave. Users are alerted to timing problems as they occur, and bus statistics that are relevant to providing insight to system operation are automatically captured. Logging of relevant events may be enabled or disabled when a sliding time window expires, by a selected address range or alternatively by external trigger events.
