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 method, computer program product and system for facilitating inter-digital signal processing (DSP) data communications. A direct memory access (DMA) controller may be configured to facilitate transfers of data between a first and a second DSP processor core coupled to the DMA controller. The DMA controller may read a data structure, referred to as a “buffer descriptor block,” to perform the data transfer. The buffer descriptor block may store both a source address and a destination address indicating where the data is to be retrieved and stored. The buffer descriptor block may further store a value, e.g., number of bytes, indicating a size of the data to be transferred. The DMA controller may then transfer the data located at the source address in the first DSP processor core, with a size, e.g., number of bytes, indicated from the buffer descriptor block, to the destination address in the second DSP processor core.

摘要： A method for operating plurality of DSL modem transmitters integrated within a circuit card. The method includes each DSL modem transmitter: generating a full power physical frame when the DSL modem transmitter is provided with data to transmit; generating a low power physical frame having a control channel signal component and no data; and selecting between the full power physical frame and the low power physical frame for transmission from the DSL modem transmitter, wherein selection of the low power physical frame for transmission from the DSL modem transmitter is based only on the DSL modem transmitter having no data to transmit. The method further includes limiting aggregate flow of data to the plurality of DSL modem transmitters such that a total power required by the plurality of DSL modem transmitters is held below a predefined target power level.

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.
