Abstract:
1. Trace circuitry for monitoring a behaviour of at least one processor and for generating a trace stream containing items of trace data indicative of processing activities of said at least one processor executing a stream of instructions, said stream of instructions comprising different types of instructions, each type specifying a different operation, at least one type of instruction comprising a multiple transfer instruction specifying a plurality of data transfers; said trace circuitry configured to respond to detection of said at least one processor executing at least one of said multiple transfer instructions and to an indication that at least one of said plurality of data transfers is to be traced: to output in said trace stream for each of said data transfers to be traced a value indicative of a predetermined index value associated with said data transfer, said at least one multiple transfer instruction having predetermined index values associated with each of said plurality of data transfers, such that said predetermined index value provides individual identification of each of said data transfers.
