    • Automatic queue sizing for data flow applications for an integrated circuit is described. Queue sizes for queues of a dataflow network are initialized to a set of first sizes for running as distributed actors without having to have centralized control. If it is determined there is a deadlock, causes for the dataflow network being deadlocked are analyzed with a controller coupled thereto to select a first actor thereof. The first actor of the dataflow network is selected as being in a stalled write phase state. Queue size is incremented for at least one queue of the queues to unlock the first actor from the stalled write phase state. The running, the determining, the analyzing, and the incrementing are iteratively repeated to provide a second set of sizes for the queue sizes sufficient to reduce likelihood of deadlock of the data flow network.
    • 描述用于集成电路的数据流应用的自动队列大小。 数据流网络队列的队列大小被初始化为一组第一个大小,用于作为分布式角色进行运行,而无需集中控制。 如果确定存在死锁,则与其耦合的控制器分析数据流网络处于死锁状态的原因,以选择其第一actor。 数据流网络的第一个演员选择为处于停止的写入阶段状态。 对于至少一个队列队列,队列大小递增,以使第一个actor从停止的写入阶段状态解锁。 迭代地重复运行,确定,分析和递增,以为足以减少数据流网络死锁可能性的队列大小提供第二组大小。
