摘要： Task context information is transferred concurrently from a processor core to an accelerator and to a context memory. The accelerator performs an operation based on the task context information and the context memory saves the task context information. The order of transfer between the processor core is based upon a programmable indicator. During a context restore operation information is concurrently provided to data bus from both the accelerator and the processor core.

摘要： A data processing system includes a processor core and ordering scope manager circuitry. The processor core sends an indication of a first ordering scope identifier for a current ordering scope a task currently being executed by the processor core and a second ordering scope identifier for a next-in-order ordering scope of the task. The ordering scope manager receives the indication the first and second ordering scope identifiers from processor core, and, provides a no task switch indicator to the processor core in response to determining that the first task is a first-in-transition-order task for the first ordering scope identifier and that processor core is authorized to execute the next-in-order ordering scope. The processor core transitions from executing in the current ordering scope to executing in the next-in-order ordering scope without performing task switch in response to the no task switch indicator being provided.

摘要： Each task assigned to a core can be considered an “active” task. Sequential strobe signals of a watchdog signal can be spaced apart in time by a certain duration. The duration between strobe signals is longer than the expected duration of an active task. By knowing that all tasks being monitored are expected to execute within an expected amount of time, the duration between the strobe signals can be set to be longer than that expected amount of time. If a task has not transitioned to inactive by a next strobe, a watchdog error has occurred.
摘要翻译：分配给核心的每个任务可以被认为是一个“主动”任务。看门狗信号的顺序选通信号可以在时间上间隔一段持续时间。选通信号之间的持续时间长于活动任务的预期持续时间。通过知道所有被监视的任务预期在预期的时间内执行，选通信号之间的持续时间可以被设置为比预期的时间长。如果任务没有被下一个选通转换为非活动状态，则发生看门狗错误。

摘要： A floating point value can represent a number or something that is not a number (NaN). A floating point value that is a NaN having data field that stores information, such as a propagation count that indicates the number of times a NaN value has been propagated through instructions. A NaN evaluation instruction can determine whether one or more operands is a NaN operand of a particular type, and if so can generate a result that is a NaN of a different type. An exception can be generated based upon the NaN of the different type being provided as a resultant.

摘要： A data processing system includes a processor core and a hardware module. The processor core performs tasks on data packets. The hardware module stores a first ordering scope identifier at a first storage location of the ordering scope manager. The first ordering scope identifier indicates a first ordering scope that a first task is operating in. The ordering scope manager increments the first ordering scope identifier to create a new ordering scope identifier. In response to determining that the processor core is authorized to transition the first task from the first ordering scope to a second ordering scope associated with the new ordering scope identifier, the ordering scope manager provides hint information to the processor core. The processor core transitions from the first ordering scope to the second ordering scope without completing a task switch in response to the hint information.

摘要： Threads may be scheduled to be executed by one or more cores depending upon whether it is more desirable to minimize power or to maximize performance. If minimum power is desired, threads may be schedule so that the active devices are most shared; this will minimize the number of active devices at the expense of performance. On the other hand, if maximum performance is desired, threads may be scheduled so that active devices are least shared. As a result, threads will have more active devices to themselves, resulting in greater performance at the expense of additional power consumption. Thread affinity with a core may also be taken into consideration when scheduling threads in order to improve the power consumption and/or performance of an apparatus.
摘要翻译：线程可以被调度为由一个或多个核执行，这取决于是否更希望最小化功率或最大化性能。如果需要最小功率，则可以调度线程，使得有效设备是最共享的; 这将以牺牲性能为代价来最小化活动设备的数量。另一方面，如果需要最大性能，则可以调度线程，使得有源设备最不共享。因此，线程将自己拥有更多的活动设备，导致更高的性能，而牺牲额外的功耗。为了提高设备的功耗和/或性能，调度线程时也可以考虑与核心的线程亲和度。

摘要： A method includes initializing a counter value of a hardware counter. The method further includes iteratively adjusting the counter value and storing an initialization value to a memory location using a memory address based on the counter value. The method also includes generating an interrupt request based on a comparison of the counter value to a waitpoint value concurrent with iteratively adjusting and storing. A memory device includes a memory array and an initialization module. The initialization module includes a counter, a register to store a waitpoint value, write logic configured to write an initialization value to a memory location of the memory array associated with a memory address that is based on a counter value of the counter, and interrupt logic configured to generate an interrupt request based on a comparison of the counter value of the counter to the waitpoint value.

摘要： A method for controlling a memory scrubbing rate based on content of the status bit of a tag array of a cache memory. More specifically, the tag array of a cache memory is scrubbed at smaller interval than the scrubbing rate of the storage arrays of the cache. This increased scrubbing rate is in appreciation for the importance of maintaining integrity of tag data. Based on the content of the status bit of the tag array which indicates modified, the corresponding data entry in the cache storage array is scrubbed accordingly. If the modified bit is set, then the entry in the storage array is scrubbed after processing the tag entry. If the modified bit is not set, then the storage array is scrubbed at a predetermined scrubbing interval.
摘要翻译：一种用于基于高速缓冲存储器的标签阵列的状态位的内容来控制存储器擦除速率的方法。更具体地说，高速缓冲存储器的标签阵列以比缓存的存储阵列的擦除速率更小的间隔进行擦除。对于保持标签数据完整性的重要性，这种提高的清洗率是值得赞赏的。基于指示被修改的标签阵列的状态位的内容，相应地擦除缓存存储阵列中的相应数据条目。如果修改的位被设置，则在处理标签条目之后擦除存储阵列中的条目。如果未设置修改的位，则以预定的擦洗间隔擦除存储阵列。
