摘要： A processing system includes a memory and a first core configured to process applications. The first core includes a first cache. The processing system includes a mechanism configured to capture a sequence of addresses of the application that miss the first cache in the first core and to place the sequence of addresses in a storage array; and a second core configured to process at least one software algorithm. The at least one software algorithm utilizes the sequence of addresses from the storage array to generate a sequence of prefetch addresses. The second core issues prefetch requests for the sequence of the prefetch addresses to the memory to obtain prefetched data and the prefetched data is provided to the first core if requested.

摘要： A codec detects congestion in a packet network and responds via a session control protocol to re-negotiate codec-type and/or parameters with the receiving codec to reduce bit rate for supporting a session. Once the connection and session are established, encoded packets start flowing between the two codecs. A control entity sends and receives network congestion control packets periodically in the session. The congestion control packets provide a “heartbeat” signal to the receiving codec. When the network is not congested, all “heartbeat” packets will be passed through the network. As network congestion increases, routers within the network discard excess packets to prevent network failure. The codecs respond to the missing packets by slowing down the bit rate or proceeding to renegotiate a lower bit rate via the session control protocol. If there are no missing packets, the codecs detect if the session is operating at the highest bit rate, and if not, re-negotiate a higher bit rate.
摘要翻译：编解码器检测分组网络中的拥塞，并通过会话控制协议进行响应，以使用接收编解码器重新协商编解码器类型和/或参数，以减少支持会话的比特率。一旦建立了连接和会话，编码的数据包将在两个编解码器之间开始流动。控制实体在会话中定期发送和接收网络拥塞控制报文。拥塞控制分组向接收编解码器提供“心跳”信号。当网络不拥塞时，所有“心跳”数据包将通过网络传递。随着网络拥塞的增加，网络内的路由器丢弃多余的数据包，防止网络故障。编解码器通过减慢比特率或通过会话控制协议进行重新协商较低的比特率来响应丢失的分组。如果没有丢失数据包，则编解码器检测会话是否以最高比特率运行，如果不是，则重新协商更高的比特率。

摘要： A facility is provided for managing register maps for map-based indirect register file access within a processor. The management facility includes a register mapping including a set of maps, each map of the set of maps having a plurality of map registers. A set of actual registers is indirectly accessed by the processor via map entries of the set of maps. The number of actual registers in the set of actual registers is greater than the number of map entries in the set of maps, and the map entries of the set of maps reference only a subset of the set of actual registers at any given time. The facility includes managing updates to multiple entries of the set of maps of the register mapping by updating multiple map entries of at least one map of the set of maps responsive to executing a single update instruction.

摘要： Method and apparatus for making limited internal-node communication facilities externally visible in a packet switching network. Internal-node communication facilities are called intranode links, can include any cable, channel, bus, etc. over which data passes, and are used to connect the multiple subnodes within a given node. Each subnode contains a switching mechanism and routes packets to other nodes, subnodes, or user applications. Each node provides network control functions such as topology, directory, path selection, and bandwidth management which can manage intranode links in the same manner that internode links are currently managed.

摘要： A bilateral transmission line repeater is disclosed in which opposite directions of transmission are separated into different frequency bands. The amplifiers for each direction of transmission include an automatic gain control circuit for controlling the gain of the amplifier. Gain control for the inward bound amplifier (toward a central location such as a telephone central office) is under the control of an automatic gain control signal derived from the outward bound signal as well as from the inward bound signal. Feedback around the gain control amplifier is accomplished using a current mirror circuit to avoid loading the amplifier output.

摘要： Access control for a packet communications network includes a dynamic bandwidth updating mechanism which continuously monitors the mean bit rate of the signal source and the loss probability of the connection. These values are filtered to remove noise and then used to test whether the values fall within a pre-defined acceptable adaptation region in the mean bit rate, loss probability plane. Values falling outside of this region trigger bandwidth updating procedures which, in turn, result in acquiring a new connection bandwidth, and determining new filter parameters and new parameters for a leaky bucket access mechanism.

摘要： A packet communications system provides for point-to-point packet routing and multicast packet routing to limited subsets of nodes in the network, using a routing field in the packet header which is processed according to two different protocols. A third protocol is provided in which a packet can be multicast to the limited subset even when launched from a node which is not a member of the subset. The routing field includes a first portion which contains the route labels necessary to deliver the packet to the multicast subset. A second portion of the routing field contains the multicast subset identifier which can then be used to deliver the packet to all of the members of the multicast subset. Provision is made to backtrack deliver the packet to the last node identified before the multicast subset if that last node is itself a member of the subset.

摘要： A method and system for providing dynamic addressability of data elements in a vector register file with subword parallelism. The method includes the steps of: determining a plurality of data elements required for an instruction; storing an address for each of the data elements into a pointer register where the addresses are stored as a number of offsets from the vector register file's origin; reading the addresses from the pointer register; extracting the data elements located at the addresses from the vector register file; and placing the data elements in a subword slot of the vector register file so that the data elements are located on a single vector within the vector register file; where at least one of the steps is carried out using a computer device so that data elements in a vector register file with subword parallelism are dynamically addressable.
