摘要： A data processing apparatus executes instructions in a sequence of pipelined execution stages. An error detection unit twice samples a signal associated with execution of an instruction and generates an error signal if the samples differ. An exception storage unit maintains an age-ordered list of entries corresponding to instructions issued to the execution pipeline and can mark an entry to show if the error signal has been generated in association with that instruction. A timer unit is responsive to generation of the error signal to initiate timing of a predetermined time period. An error recovery unit initiates a soft pipeline flush procedure if an oldest pending entry in the list has said error marker stored in association therewith and initiates a hard pipeline flush procedure if said predetermined time period elapses, said hard flush procedure comprising resetting said pipeline to a predetermined state.
摘要翻译：数据处理装置以流水线执行阶段的顺序执行指令。错误检测单元对与执行指令相关联的信号进行两次采样，并且如果样本不同则产生误差信号。异常存储单元维护与发出到执行流水线的指令相对应的条目的年龄排序列表，并且可以标记条目以显示是否已经与该指令相关联地生成了错误信号。定时器单元响应于产生误差信号以启动预定时间段的定时。如果列表中的最旧的等待条目具有与其相关联地存储的所述错误标记，则错误恢复单元启动软管道冲洗过程，并且如果所述预定时间段过去则启动硬管道冲洗过程，所述硬冲洗程序包括将所述流水线重置为预定状态。

摘要： A data processing apparatus and method of data processing are provided. The data processing apparatus comprises execution circuitry configured to execute a sequence of program instructions. Checkpoint circuitry is configured to identify an instance of a predetermined type of instruction in the sequence of program instructions and to store checkpoint information associated with that instance. The checkpoint information identifies a state of the data processing apparatus prior to execution of that instance of the predetermined type of instruction, wherein the predetermined type of instruction has an expected long completion latency. If the execution circuitry does not complete execution of that instance of the predetermined type of instruction due to occurrence of a predetermined event, the data processing apparatus is arranged to reinstate the state of the data processing apparatus with reference to the checkpoint information, such that the execution circuitry is then configured to recommence execution of the sequence of program instructions at that instance of the predetermined type of instruction.
摘要翻译：提供数据处理装置和数据处理方法。该数据处理装置包括被配置为执行程序指令序列的执行电路。检查点电路被配置为识别程序指令序列中的预定类型的指令的实例，并且存储与该实例相关联的检查点信息。检查点信息在执行预定类型的指令的该实例之前识别数据处理装置的状态，其中预定类型的指令具有期望的长完成延迟。如果执行电路由于发生预定事件而没有完成预定类型的指令的实例的执行，则数据处理装置被配置为参照检查点信息恢复数据处理装置的状态，使得然后，执行电路被配置为在预定类型的指令的那个情况下重新开始执行程序指令的序列。
