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. At least one of said trace data sources includes 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. A controller is coupled to 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. 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.

摘要： A system-on-chip integrated circuit 2 is provided with multiple data processing circuits 4, 6, 8 each with an associated diagnostic interface circuit 16, 18, 20 connected via a diagnostic transaction bus 14 to a diagnostic transaction master circuit 12. The diagnostic master transaction circuit 12 issues diagnostic transaction requests to the diagnostic interface circuits 16, 18, 20. If the associated data processing circuits 4, 6, 8 are powered-down, or otherwise non responsive, then the diagnostic interface circuit 16, 18, 20 returns a diagnostic bus transaction error signal to the diagnostic transaction master circuit 12. A sticky-bit latch 30 within each diagnostic interface circuit 16, 18, 20 serves to record a power-down event and force generation of the diagnostic bus transaction error signal until that sticky bit is cleared by the diagnostic mechanisms. This ensure the diagnostic mechanisms are made aware of the power-down event so they may take any appropriate remedial action that might be necessary as a result of that power-down event.

摘要： A trace data system is provided in which flush request signals are generated and passed to trace data sources to trigger them to output any buffered trace data they are storing which was generated prior to the flush request being signalled. When the trace data has been flushed from these trace data sources, they signal this by generating a flush complete signal. The flushing of trace data may advantageously be performed prior to a power-down operation and using a trace bus bridge.

摘要： A tracing circuit 8 within an apparatus for data processing 2 generates trace data including instruction trace words encoding trace events W, E, N representing program instruction execution. The instruction trace words have a predetermined length and each represent a sequence of trace events corresponding to a combination of execution of one or more program instructions combined with one or more trace events that are other than execution of a program instruction word. Particular examples are a sequence of executed program instructions terminated by a program instruction that fails its condition codes or a sequence of wait processing cycles terminated by a program instruction that executes.

摘要： The present invention provides an apparatus and method for facilitating debugging of sequences of processing instructions. The apparatus comprises a processing circuit for executing processing instructions, the processing circuit having multiple states of operation, with each state of operation being assigned a context identifier to identify the state of operation. Further, logic is provided for facilitating debugging of sequences of processing instructions executed by the processing circuit. The logic comprises control logic, responsive to control parameters, to perform predetermined actions to facilitate debugging, and triggering logic for generating the control parameters dependent on data received from the processing circuit indicative of the processing being performed by the processing circuit. The triggering logic comprises at least one context identifier comparator for comparing a context identifier provided within the data received from the processing circuit with a predetermined context identifier, and to generate a signal indicating whether that context identifier matches the predetermined context identifier. By this approach, the present invention enables a data processing apparatus to be provided with tracing mechanisms and/or debugging mechanisms which can reliably operate even in situations where the sequences of processing instructions from different states of operation occupy overlapping regions in the memory's address space.
