Abstract
A method of tracing data processor activity with recover from detection of trace stream corruption. If the first trace data following detection of corruption is not a program counter sync point, then the trace transmits an indication of the current program counter address in an offset format from the program counter address of a last transmitted program counter sync point and then transmits trace data in event offset format. If the first trace data following detection of corruption is a program counter sync point, then the trace transmits trace data in event offset format.
