    • When a processor within a computer system performs a synchronization operation, the system interface within the node delays subsequent transactions from the processor until outstanding coherency activity is completed. Therefore, the computer system may employ asynchronous operations. The synchronization operations may be used when needed to guarantee global completion of one or more prior asynchronous operations. In one embodiment, the synchronization operation is placed into a queue within the system interface. When the synchronization operation reaches the head of the queue, it may be initiated within the system interface. The system interface further includes a request agent comprising multiple control units, each of which may concurrently service coherency activity with respect to a different transaction. Furthermore, the system interface includes a synchronization control vector register which stores a bit for each control unit. Upon initiation of the synchronization operation within the system interface, bits corresponding to those control units which are performing coherency activity (i.e. those which are not idle) are set while other bits are cleared. As each control unit returns to the idle state, the corresponding bit is cleared as well. Once all the bits within the synchronization control vector register are cleared, the coherency activity which was outstanding when the synchronization operation was initiated is complete. The synchronization operation may then be completed.
    • 当计算机系统内的处理器执行同步操作时,节点内的系统接口会延迟来自处理器的后续事务,直到完成一致的一致性活动。 因此,计算机系统可以采用异步操作。 当需要保证一个或多个在先的异步操作的全局完成时,可以使用同步操作。 在一个实施例中,同步操作被放置在系统接口内的队列中。 当同步操作到达队列的头部时,可以在系统界面内启动。 该系统接口还包括一个包含多个控制单元的请求代理,每个控制单元可以相对于不同的事务同时提供一致性活动。 此外,系统接口包括存储每个控制单元的位的同步控制向量寄存器。 在系统接口中启动同步操作之后,在执行一致性活动的那些控制单元(即那些不空闲的)的对应的位被设置,而其它位被清除。 当每个控制单元返回到空闲状态时,相应的位也被清除。 一旦清除了同步控制向量寄存器中的所有位,完成了同步操作启动时未完成的一致性活动。 然后可以完成同步操作。

    • A 3D object is represented by a descriptor, wherein a model of the 3D object is a 3D point cloud. A local support for each point p in the 3D point cloud is located, and reference x, y, and z axes are generated for the local support. A polar grid is applied according to the references x, y, and z axes a along an azimuth and a radial directions on an xy plane centered on the point p such that each patch on the grid is a bin for a 2D histogram, wherein the 2D histogram is a 2D matrix F on the grid and each coefficient of the 2D matrix F corresponds to the patch on the grid. For each grid location (k, l), an elevation value F(k, l) is estimated by interpolating the elevation values of the 3D points within the patches to produce the descriptor for the point p.
    • 3D对象由描述符表示,其中3D对象的模型是3D点云。 定位在3D点云中的每个点p的本地支持,为本地支持生成参考x,y和z轴。 根据参考x,y和z轴a沿着位于点p上的xy平面上的方位角和径向方向施加极坐标网格,使得网格上的每个贴片是2D直方图的仓,其中, 2D直方图是网格上的2D矩阵F,2D矩阵F的每个系数对应于网格上的补丁。 对于每个网格位置(k,l),通过内插补片内的3D点的高程值来估计高程值F(k,l),以产生点p的描述符。
