ABSTRACT:
When a plurality of simultaneous, preselected target processor events are detected, a multiple-event sync marker is generated that identifies the preselected events and relates the occurrence of these events to timing trace stream. The sync marker for the plurality of preselected events differs from a single event sync marker by including at least one additional packet. The additional packet includes logic signals stored at locations related to each identified event.
