The present invention relates to the generation of trace elements within a data processing apparatus having one or more components whose behaviour is to be traced. A trace module is disclosed which is operable to trace changes in a subset of architectural state of a data processing apparatus with which the trace module is coupled. The trace module comprises a trace generation unit operable to receive input signals from one or more components of the data processing apparatus indicative of a change in the subset of architectural state and to generate from one or more of the input signals a number of trace elements indicative of the change so as to enable a recipient of the trace elements to subsequently reconstruct the subset of architectural state. The trace module also comprises a table maintained by the trace generation unit to identify architectural state derivable from previously generated trace elements, the trace generation unit referencing the table in order to determine which trace elements to generate during the trace generation. By providing a table which identifies architectural state which is derivable from previously generated trace elements, the number of trace elements that need to be generated is significantly reduced. This reduction is achieved because the table provides a record of the architectural state which has already been provided to the recipient. Knowing the architectural state which has already been provided to the recipient enables the trace generation unit to determine whether changes in architectural state can be derived by the recipient. Accordingly, the trace generation unit can refer to the table and only those trace elements relating to changes in architectural state which are not derivable by the recipient need be generated. Hence, if the trace generation unit determines that the recipient is able to derive architectural state then no trace elements relating to those changes need be generated.
