摘要： A trace data formatter 30 assembles trace data frames 50. These trace data frames 50 include bytes which may either serve to carry a trace data source identifier ID or trace data. A system being traced has multiple trace data sources 12, 14, 16, 18 and when the trace data source which is generating the current trace data stream changes then a trace data source identifier ID is inserted within the trace data stream.

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： 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.

摘要： A data processing system is provided in which processing circuitry performs at least one of a series of data processing operations in dependence upon a set of data values and control circuitry controls execution of the data processing operations. Control path error detection circuitry is provided for detecting a control path error associated with an error in operation of the control circuitry and data path error handling circuitry is arranged to handle recovery from errors in the data values. The control path error detection circuitry is configured to cause the data path error handling circuitry to perform recovery from detected control path errors enabling the series of data processing operations to continue despite the occurrence of the control path error. An associated method and computer program product are also provided.

摘要： A data processing system includes a register file (2) having a plurality of registers storing respective register data values and an associated register value cache (12) having a plurality of storage locations (14) storing corresponding cache data values. There are fewer cache data values than registers. When a register is to be read, both the register data value and, if present, a cache data value from a corresponding storage location (14) within the register value cache (12) are read and compared by a comparator (18). This generates a match signal which indicates if the data values do not match that one of the data values is in error. The match signal stalls the processing and a CRC code initially stored with the cache data value and recalculated based upon the read cache data value are compared to determine whether or not the cache data value has changed since it was stored. If the cache data value has not changed, then it is correct and is output instead of the register data value. Alternatively, if the cache data value has changed, then the register data value is output.
摘要翻译：数据处理系统包括具有存储相应寄存器数据值的多个寄存器的寄存器文件（2）和具有存储对应高速缓存数据值的多个存储位置（14）的关联寄存器值缓存（12）。缓存数据值比寄存器少。当要读取寄存器时，寄存器数据值和寄存器值高速缓冲存储器（12）中对应的存储位置（14）的高速缓存数据值（如果存在）都被比较器（18）比较。这产生一个匹配信号，它指示数据值是否与数据值之一不符。匹配信号使处理停止，并且比较最初存储有高速缓存数据值并基于读取的高速缓存数据值重新计算的CRC码，以确定高速缓存数据值是否已经被存储以来已经改变。如果缓存数据值没有改变，那么它是正确的并且是输出而不是寄存器数据值。或者，如果缓存数据值已经改变，则输出寄存器数据值。
