摘要： A data processing apparatus is provided with packing circuitry 130 arranged 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.

摘要： Within an integrated circuit (2) independently controllable domains (4, 6, 8, 10, 5 12, 14) may be unable to complete pending transactions taking place between domains. Each domain is provided with a state machine (20, 22) which is responsive to the state of the state machine within the other domain and when this indicates that the other domain is not communicating triggers modified behavior. This can provide that the predetermined transaction protocol is not broken and/or complete a partially completed transaction when the domain concerned has recovered from an error or other event which disrupted the communication.
