Abstract
PURPOSE: To decrease the order execution time and thus to shorten the process time for trace by carrying out the process with installation of address register AR which stores the trace data into the idle memory, the means which renews the AR with every storage, and others.
CONSTITUTION: In case the interruption occurs at the communication control unit and the trace is given, the trace data is taken out of the circuit control table or the external register. And the order pattern is analyzed at order code analysis part 10. When the order to store the trace data is judged, the trace data is stored in the address shown by trace register Rn(5-3'). After this, the address is increased and renewed, and this result is compared with trace final AR(5-2') at the comparator to decide the memory is traced up to the last. And when the final of the memory is decided, the contents of the head AR in the idle area of AR(5-1') is transferred to Rn(5-3') to prepare for the next trace. As a result, the program steps for the trace data collection within the communication control unit can be shortened.
