<p>An integrated circuit incorporates internal circuits and a trace data collecting circuit. The trace data collecting circuit collects signals as trace data from the internal circuits. The trace data collecting circuit comprises a collecting and compressing portion that collects the trace data from the internal circuits and compresses the collected trace data, a storage portion that stores the collected and compressed trace data of the collecting and compressing portion, a controlling portion that controls the collecting and compressing portion as well as the storage portion such that the trace data are collected according to set tracing conditions, and a readout portion that reads the trace data out of the storage portion and outputs the read data to the outside of the integrated circuit.</p> |
