Abstract
A data processing apparatus is provided with packing circuitryarranged to receive said source data elements from said trace data receiver and applies a packing protocol to said source data elements to pack data of source data elements of a source trace stream into a packed trace data stream for supply to trace accepting circuitry in a format comprising acceptance data elements. The acceptance data elements have a bit-length that is not a factor of the source data element bit-length. In some arrangements the source data elements are non byte-sized data elements. In alternative arrangements, the packing circuitry packs a first positive integer number of source data elements into a data chunk comprising a second, different positive integer number of acceptance data elements. In further alternative arrangements the source trace protocol has a variable packet size and the data chunk is formed from a first portion comprising data of the source data elements and a further portion comprising a size-indicating code.
