Apparatus and method for processing trace data streams

Abstract

An apparatus comprising: a lower-layer decoder configured to decode a data stream formatted according to a lower-layer protocol that interleaves portions of a first data stream and one or more additional data streams to produce separated data streams comprising the first data stream and separately the one or more additional data streams; and a higher-layer decoder configured to decode the first data stream formatted according to a higher-layer protocol to produce trace data, the higher-layer decoder comprising: synchronisation logic configured to process the first data stream to detect a data pattern within the first data stream as a synchronisation event; and decoding logic configured to use the synchronisation event to synchronise decoding of the received first data stream to produce the trace data.
