摘要： A method and system and calibration technique for power measurement and management over multiple time frames provides responsive power control while meeting global system power consumption and power dissipation limits. Power output of one or more system power supplies is measured and processed to produce power values over multiple differing time frames. The measurements from the differing time frames are used to determine whether or not system power consumption should be adjusted and then one or more devices is power-managed in response to the determination. The determination may compare a set of maximum and/or minimum thresholds to each of the measurements from the differing time frames. A calibration technique uses a precision reference resistor and voltage reference controlled current source to introduce a voltage drop from the input side of a power supply sense resistor calibration is made at the common mode voltage of the power supply output.

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 histogram difference method and system for power/performance measurement and management has low data storage requirements while supporting multiple monitoring applications having different update rates. Histogram data for power usage and/or performance mode is collected at a predetermined rate and the histogram data is read out at periodic intervals by the monitoring applications. The monitoring applications subtract the histogram data from previously read histogram data set to determine a interval difference histogram. The minimum and maximum values for the interval are the lowest-valued and highest-valued bin in the interval difference histogram that have a count greater than zero. The average value for the interval is the mean of the interval difference histogram. A conservative bound of the maximum and minimum values for a system can be determined by adding the values of the maximum and minimum values determined for each subsystem in the system.

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： 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 data processing system attributes energy consumption to individual program segments or threads includes a processor that executes a first thread during a first portion of a measurement interval and a second thread during a second portion of the interval. An energy monitor measures the total energy during the interval. Energy attribution code attributes a first amount of the total energy to the first thread and a second amount to the second thread based in part on the execution times of the threads. The code may define a range of possible energy values by determining maximum and minimum energy constraints for the threads. The invention may also be extended to a multiprocessor environment and to a simultaneous multithreading (SMT) processor. In addition, the process may be expanded to determine energy consumed by various peripheral units such as hard disk controllers and the like.

摘要： A low power DSL modem transmitter, suitable for incorporation in integrated DSLAM server line cards, transmits full power physical frames which include a control channel and a data field when data is available for transmission and physical frames having only a control channel or a control channel and a low power synchronization field when data is not available for transmission. And a method for controlling the total power dissipated in the integrated DSLAM by selectively restricting the flow of data packets to the DSLs.
