ABSTRACT:
A data processing system adapted to perform a plurality of interleaved data processing functions (2, 4, 6), characterised in that each data processing function (2, 4, 6) stores self-diagnostic trace data in a memory (16) shared between the data processing functions (2,4,6) and the data processing system performs a trace function (8) which reads the trace data from the shared memory (16) and correlates the trace data into a single output. The disclosed system provides a trace facility in which a single correlated trace output is produced from the trace messages produced by all the different data processing functions (2, 4, 6). A single correlated output enables errors involving the interaction of two or more data processing functions (2, 4, 6) to be more easily identified.
