摘要： A method of determining an adaptive early skip indication (ESI) threshold during block motion compensation encoding of digital video data is disclosed. The method includes setting an ESI threshold minimum value below which no degradation in the block motion compensation encoding occurs; setting an ESI threshold maximum value above which degradation in the block motion compensation encoding is considered unacceptable; determining that a processor load state of the processor during block motion compensation encoding is one of an overloaded state, a normal loaded state, and an under loaded state; when the processor load state is determined to be in an overloaded state, increasing the adaptive ESI threshold to a value below the ESI threshold maximum value thereby decreasing a number of macroblocks in the digital video data that are block motion compensation encoded; when the processor load state is determined to be in a normal loaded state, maintaining the adaptive ESI threshold at its current value; and when the processor load state is determined to be in an under loaded state, decreasing the adaptive ESI threshold to a value above the ESI threshold minimum value thereby increasing a number of macroblocks in the digital video data that are block motion compensation encoded. A block motion compensation encoding devices is also disclosed that implements the method above. A computer readable medium is also disclosed that stores instructions, which when executed by a processing unit, performs the method above.

摘要： A bus monitoring and debugging system operating independently without impacting the normal operation of the CPU and without adding any overhead to the application being monitored. Users are alerted to timing problems as they occur, and bus statistics that are relevant to providing insight to system operation are automatically captured. Logging of relevant events may be enabled or disabled when a sliding time window expires, or alternatively by external trigger events.

摘要翻译： 总线监控和调试系统独立运行，不会影响CPU的正常运行，并且不会对正在监视的应用程序造成任何开销。 用户在发生定时问题时收到警报，并自动捕获与提供系统操作的洞察相关的总线统计信息。 当滑动时间窗口到期时，或者通过外部触发事件，可以启用或禁用相关事件的记录。

摘要： Management of access to shared resources within a system comprising a plurality of requesters and a plurality of target resources is provided. A separate arbitration point is associated with each target resource. An access priority value is assigned to each requester. An arbitration contest is performed for access to a first target resource by requests from two or more of the requesters using a first arbitration point associated with the first target resource to determine a winning requester. The request from the winning requester is forwarded to a second target resource. A second arbitration contest is performed for access to the second target resource by the forwarded request from the winning requester and requests from one or more of the plurality of requesters using a second arbitration point associated with the second target resource.
