Abstract

PURPOSE: To make small the size of harware, by compressing the amount of information through the tracing based on the priority attached to each group, by dividing the traced signal into groups.
CONSTITUTION: In tracing the failure retrieval, traced signal is divided into suitable groups. Although the size and content of each group are depending on group, since it is general that weight is made relating to the failure from the standpoint of content, the trace information of each group is given priority. The logic signal being tracing objective is fed from the processor with groups A...N divided. The logic signal of each group is compared with the condition before by one at the comparison circuit 4, and if conditional change is present, it is stored in the trace memory 6. In this case, the priority judgement circuit 5 is operated so that storage can be made from the information of high priority group. Important conditional change can surely be stored for tracing.
