Abstract
A data processing apparatus and method for generating trace elements is provided. The data processing apparatus comprises logic producing a series of data elements, indicative of the operation or state of all or part of the logic. Trace logic is provided for receiving indications of these data elements, and for generating from the indications a stream of trace elements. When for a given data element, at least part of the data element is derivable from a reference to a control value stored in a storage element, the trace logic is operable, dependent on that data element, to omit that part of the associated data element indication from the corresponding trace element generated in respect of the data element, instead including a reference to the corresponding storage element. A trace analysing apparatus can then be used to reconstruct such omitted information based on a copy of the relevant storage element.
