摘要： A data processing system 1 has a processor core 2 which is programmable to act as one of a plurality of virtual machines each identified by a virtual machine identifier, each virtual machine acting in one of a plurality of contexts each identified by a context identifier, each context executing a sequence of program instructions, each program instruction having one or more associated memory addresses. The data processing system has diagnostic circuitry 10 for performing diagnostic operations on the processor core. Diagnostic control circuitry 12 is provided which is responsive to current values of the virtual machine identifier, the context identifier and at least one of the one or more associated memory addresses to trigger the diagnostic circuitry 10 to perform diagnostic operations.

摘要： A data processing apparatus is provided, comprising monitored circuitry for performing activities, trace circuitry for producing a stream of trace elements representative of at least some of these activities, and detection circuitry for detecting the occurrence of a predetermined subset of the activities for which the trace circuitry is producing trace elements. When an activity in that predetermined subset of activities is detected a timing indication is added to the stream of trace elements. Hence, the valuable trace bandwidth- may be preserved, by limiting the trace elements for which a timing indication is added into the trace stream to a predetermined subset of the activities for which trace elements are generated, and the valuable global or relative timing accuracy of those activities represented in the trace stream is retained, without flooding the trace stream with timing indications.

摘要： A data processing apparatus is provided which is configured to select 2M selected identifiers within a possible range of up to 2N identifiers, where M≦N. The data processing apparatus comprises a selection storage unit configured to store N+1 identifier selection bits, wherein a position of a marker bit in the N+1 identifier selection bits determines M, and an identifier selection unit configured to determine the 2M selected identifiers. The 2M selected identifiers are defined by a base identifier and 2M−1 identifiers incrementally following that base identifier. N−M bits of the N+1 identifier selection bits form N−M most significant bits of the base identifier, and M trailing zeroes form the M least significant bits of the base identifier.

摘要： A data processing apparatus having one or more trace data sources is provided in which the trace data sources operate to generate respective streams of trace data. At least one of said trace data sources comprises a trace data generator responsive to activity in monitored circuitry to generate trace data representing said activity. A synchronization marker generator is coupled to the trace data generator and operates to generate a synchronization marker and insert the synchronization marker into the trace data stream. The synchronization marker identifies a synchronization position in the trace data stream. A controller is coupled to the synchronization marker generator, and operates to initiate the synchronization marker generator to generate and insert a synchronization marker into the trace data stream. The controller controls initiation in dependence on behavior of the data processing apparatus downstream of the trace data generator with respect to trace data flow. In this way, the downstream behavior of the data processing apparatus can be made to influence the rate and timing of insertion of synchronization markers into a trace data stream, thereby reducing the likelihood of the volume of trace data resulting in an overflow condition in the downstream circuitry.
