DEVICE FOR PROCESSING DATA, METHOD FOR GENERATING TRACE DATA AND DEVICE FOR ANALYZING TRACE DATA

摘要

PROBLEM TO BE SOLVED: To solve a problem that there is disadvantage that a pin count is consumed when each trace data source is provided with a discrete trace mechanism. SOLUTION: A trace data formatter 30 assembles data frames 50. These trace data frames 50 include a plurality of bites which may either serve to carry a trace data source identifier ID or the trace data. A system being traced has many trace data sources 12, 14, 16 and 18, and the trace data source identifier ID is inserted into a trace data stream if the trace data source generating the current trace data stream changes.
