Abstract: A DMA controller allocates space at a buffer to different DMA engines based on the length of time data segments have been stored at a buffer. This allocation ensures that DMA engines associated with a destination that is experiencing higher congestion will be assigned less buffer space than a destination that is experiencing lower congestion. Further, the DMA controller is able to adapt to changing congestion conditions at the transfer destinations.

Abstract: A method of controlling polishing includes polishing a first substrate having an overlying layer on an underlying layer or layer structure. During polishing, the substrate is monitored with an in-situ monitoring system to generate a sequence of measurements. The measurements are sorted into groups, each group associated with a different zone of a plurality of zones on the substrate. For each zone, a time at which the overlying layer is cleared is determined based on the measurements from the associated group. At least one second adjusted polishing pressure for at least zone is calculated based on a pressure applied in the at least one zone during polishing the substrate, the time for the at least one zone, and the time for another zone. A second substrate is polished using the at least one adjusted polishing pressure.

Abstract: A source processor can divide each packet of a data stream into multiple segments prior to communication of the packet, allowing a packet to be transmitted in smaller chunks. The source processor can process the segments for two or more packets for a given data stream concurrently, and provide appropriate context information in each segments header to facilitate in order transmission and reception of the packets represented by the individual segments. Similarly, a destination processor can receive the packet segments packets for an ordered data stream from a source processor, and can assign different contexts, based upon the context information in each segments header. When a last segment is received for a particular packet, the context for the particular packet is closed, and a descriptor for the packet is sent to a queue. The order in which the last segments of the packets are transmitted maintains order amongst the packets.

Abstract translation: 源处理器可以在分组通信之前将数据流的每个分组划分成多个分段，从而允许以更小的分组发送分组。 源处理器可以对于给定数据流并发地处理两个或更多个分组的分段，并且在每个分段报头中提供适当的上下文信息，以有助于顺序发送和接收由各个分段表示的分组。 类似地，目的地处理器可以从源处理器接收用于有序数据流的分组分段分组，并且可以基于每个分段报头中的上下文信息来分配不同的上下文。 当针对特定分组接收到最后一个分段时，特定分组的上下文被关闭，并且分组的描述符被发送到队列。 传送数据包的最后一个段的顺序维护数据包之间的顺序。

Abstract: A method of chemical mechanical polishing a substrate includes polishing a metal layer on the substrate at a polishing station, monitoring thickness of the metal layer during polishing at the polishing station with an eddy current monitoring system, and controlling pressures applied by a carrier head to the substrate during polishing of the metal layer at the polishing station based on thickness measurements of the metal layer from the eddy current monitoring system to reduce differences between an expected thickness profile of the metal layer and a target profile, wherein the metal layer has a resistivity greater than 700 ohm Angstroms.

Abstract: A data processing device includes a plurality of devices, a processor core, a memory, and a queue manager. The processor core stores one or more commands in a command queue of the memory to be executed by the plurality of devices to implement a data transfer path. The queue manager stores a frame queue for each of the plurality of devices. Each frame queue includes a first field having a pointer to an address of the command queue, and a second field to identify a next-in-sequence frame queue. A first device stores a data descriptor in the frame queue of the second device to initiate a data transfer from the first device to the second device. The data descriptor includes a field to indicate an offset value from the address of the command queue to a location of a command to be executed by the second device.

Abstract: Techniques have been developed to facilitate evaluation of match and hash rule entries in ways that allow an implementation to decouple (i) the order in which match rules are applied to a first subset of packet header fields from (ii) the ordering of a second subset of packet header fields over which a non-commutative hash is computed. In short, the set and ordering of fields evaluated in accordance with a precedence order of rules need not correspond to the set or ordering of fields over which a hash is computed in a communications controller.

Abstract: A method includes generating, by a first software process of the data processing system, a source partition descriptor for a DMA job which requires access to a first partition of a memory which is assigned to a second software process of the data processing system and not assigned to the first software process. The source partition descriptor comprises a partition identifier which identifies the first partition of the memory. The DMA unit receives the source partition descriptor and generates a destination partition descriptor for the DMA job. Generating the destination partition descriptor includes translating, by the DMA unit, the partition identifier to a buffer pool identifier which identifies a physical address within the first partition of the memory which is assigned to the second software process; and storing, by the DMA unit, the buffer pool identifier in the destination partition descriptor.
