TRACING THE OPERATIONS OF A DATA PROCESSING APPARATUS

摘要

An apparatus for processing data is disclosed in which the operations of data processing circuitry are monitored by one or more trace data sources which generate items of trace data indicative of the data processing operations performed by the data processing circuitry. Trace data source identifiers in a resulting trace stream indicate the source of items of trace data and a selected trace data source identifier is included in the trace stream in response to a received flush request signal. All items of trace data generated before the apparatus received the flush request signal are included in the trace stream before the selected trace data source identifier, such that the conclusion of the response of the apparatus to the flush request signal can be identified.

1. Apparatus for processing data, the apparatus comprising:
one or more trace data sources configured to generate items of trace data indicative of the data processing operations performed by associated data processing circuitry; and trace stream generation circuitry configured to generate a trace stream to be output from the apparatus from the items of trace data, wherein the trace stream generation circuitry is configured to include one or more trace data source identifiers in the trace stream, wherein the apparatus is configured to receive a flush request signal and in response to the flush request signal to include a selected trace data source identifier in the trace stream, wherein the apparatus is configured to include all items of trace data generated before the apparatus received the flush request signal in the trace stream before the selected trace data source identifier is included in the trace stream.
