A tracing apparatus for tracing operational information that is output from a plurality of processing units in relation to data processing operations, the tracing apparatus comprising for each of the processing units: a counting unit configured to obtain and output a counter value for the corresponding processing unit, the counter value obtained by counting clock signals that are input to the processing unit at an operating frequency thereof; a counter value conversion unit configured to obtain and output a converted counter value for the corresponding processing unit, the converted counter value obtained by converting the counter value based on the assumption that the processing unit has a given reference operating frequency; and an adding unit configured to acquire an operational information set from the corresponding processing unit, and to add the converted counter value to the operational information set.
