Abstract
Upon detecting an occurrence of a watchpoint event for debugging a computer processing system, at least a portion of at least one message in a trace message buffer is flushed when a characteristic of the at least one of the messages matches a specified characteristic.
Claims20
A data processing system comprising:
- an interconnect;
- a central processing unit coupled to the interconnect;
- a memory coupled to the interconnect, the memory is accessed by the central processing unit via the interconnect;
- a debug circuit coupled to the interconnect, the debug circuit including:
- a trace module;
- a watchpoint module;
- a trace message buffer;
- and
- a debug control module configured to
- detect a specified system event;
- examine a plurality of messages in the trace message buffer for at least one characteristic;
- and
- selectively remove at least a portion of one or more of the messages that have the at least one characteristic.
