<P>PROBLEM TO BE SOLVED: To provide larger compression of addresses in a trace data stream. <P>SOLUTION: A trace circuit 8 has a plurality of reference address registers 30-1 which stores corresponding reference addresses. When a processing circuit 4 performs processing operation related to a related memory address, the trace circuit 8 selects one of the reference address registers 30-1 as a selected reference address register, and generates trace data elements indicative of (i) whether which of the reference address registers 30-1 is the selected reference address register and (ii) a difference between the related memory address and the reference address of the selected reference address when the difference is present. A diagnostic device 20 for analyzing a trace stream reconfigures the related memory address from the trace data elements using reference address registers 30-2. <P>COPYRIGHT: (C)2012,JPO&INPIT |
