A tracing circuit 8 within an apparatus for data processing 2 generates trace data including instruction trace words encoding trace events W, E, N representing program instruction execution. The instruction trace words have a predetermined length and each represent a sequence of trace events corresponding to a combination of execution of one or more program instructions combined with one or more trace events that are other than execution of a program instruction word. Particular examples are a sequence of executed program instructions terminated by a program instruction that fails its condition codes or a sequence of wait processing cycles terminated by a program instruction that executes.
