<p>PROBLEM TO BE SOLVED: To generate trace data using common time among processors. SOLUTION: A micro-counter register 25 in a synchronous control board 20 registers time which is counted by the order of micro-seconds and which is common to processors 1 to (n). Respective processors 1 to (n) refer to the micro-counter register 25 in case of need through a common bus 30. At the time of tracing, the generation time of events generated in each processor is read from the micro-counter register 25, the entry of trace information which is made to correspond to trace data at every event is generated, the entries of trace information are arranged on a time sequence where time is clocked and are stored in a main storage device 10 as trace information 11.</p> |
