TRACE ANALYSIS SYSTEM AND TRACE ANALYSIS METHOD

摘要

PPROBLEM TO BE SOLVED: To increase a information storage quantity of a trace memory and a code quantity required for debugging. PSOLUTION: The trace analysis system 48 is provided with: a trace analysis table 46; an instruction restoring part 62 restoring and transmitting an execution address and an execution code of trace information; and an object code list storage part 60. An object code list and trace information are read, they are cut from a final storage address stored in an address register 28 for every trace information in an opposite time direction and they are registered in the trace analysis table 46. A trace analysis method is provided with a step for inputting trace information which is compressed and converted by the format of different length, and a final storage address in the trace analysis table, a step for analyzing data in a direction opposite to a time axis, sequentially cutting trace information in a unit of information and registering it in the trace analysis table, and a step for inputting the object code list and restoring it into the execution address and the instruction code of registered trace information.
