    • A method, apparatus, and computer readable medium for synchronizing a main thread and a slave thread executing on a processor system are disclosed. For example, the method includes the following elements: transitioning the slave thread from a sleep state to a spin-lock state in response to a wake-up message from the main thread; transitioning the slave thread out of the spin-lock state to process a first work unit from the main thread; determining, at the main thread, an elapsed time period until receipt of a second work unit for the slave thread; transitioning the slave thread to the spin-lock state if the elapsed time period satisfies a threshold time period; and transitioning the slave thread to the sleep state if the elapsed time period does not satisfy the threshold time period.
    • 公开了一种用于同步处理器系统上执行的主线程和从线程的方法,装置和计算机可读介质。 例如,该方法包括以下元件:响应于来自主线程的唤醒消息将从线程从睡眠状态转换到自旋锁定状态; 将从线程转换到自旋锁定状态以从主线程处理第一工作单元; 在所述主线程处确定直到接收到所述从线程的第二工作单元的经过时间段; 如果经过时间段满足阈值时间段,则将从线程转换到自旋锁定状态; 以及如果经过时间段不满足阈值时间段,则将从线程转换到休眠状态。

    • A method is provided for routing a circuit design netlist. Nets of the netlist are grouped into a plurality of sub-netlists. For each sub-netlist, nets of the sub-netlist are routed as a function of congestion between nets of the sub-netlist. Congestion between nets of other sub-netlists in the plurality of sub-netlists is not taken into account. If two or more nets of the netlist are routed through the same routing resource, a global congestion history data set is updated to describe congestion between all nets in the netlist, and the two or more nets of the netlist are unrouted. The two or more nets are each rerouted as a function of the global congestion history data set and congestion between nets of the same sub-netlist as the net.
    • 提供了一种用于布线电路设计网表的方法。 网表的网络被分组成多个子网表。 对于每个子网表,子网表的网络作为子网表的网络之间的拥塞的功能被路由。 不考虑多个子网表中其他子网表的网络之间的拥塞。 如果网表的两个或多个网络通过相同的路由资源路由,则更新全局拥塞历史数据集,以描述网表中所有网之间的拥塞,并且网表的两个或多个网是未路由的。 两个或更多个网络每个被重新路由为全局拥塞历史数据集的功能和与网络相同的子网表的网络之间的拥塞。

    • Embodiments described in the specification include a method, system and apparatus for providing notifications. The method comprises executing a notification application to receive a watch instruction generated via execution of a messaging application, the watch instruction including an identifier of the messaging application and an identifier for a subset of messages stored in association with the messaging application; storing the watch instruction; executing the notification application to receive a notification request generated via execution of the messaging application in response to the receipt of a new message at the communication device, the notification request including an application identifier and a message identifier; determining the processor whether the message identifier matches the subset identifier; and, when the determination is affirmative, controlling the at least one output device at the processor to generate a notification signal according to override notification settings stored in the memory in association with the watch instruction.
