摘要： A remote controller is coupled to a target system via a computer network A real time probe is installed in software executing on a target system, typically a Digital Signal Processor (DSP). The remote controller includes a “debugger user interface” which accepts and interprets scoping commands issued by a developer. A controller network driver constructs appropriate network packets to be sent over the network to the target system. The target system has a control processor which runs a target network driver for receiving the network packets containing the scoping commands. The scoping commands are sent to an “embedded debugger” which performs the requested probing/scoping. When the DSP code runs across an address where the probe is installed, the embedded debugger will collect the signal values. The collected scope data will be interleaved and sent to the target network driver which, will encapsulate the information into suitable packets to send back to the controller via the network.

摘要： Digital impairments, including Robbed Bit Signaling (RBS) and impairments due to digital attenuation PAD (Packet Assembler/Disassembler) devices, may be identified in sets of Pulse Code Modulation (PCM) signal levels, such as sets of Digital Impairment Learning (DIL) signals transmitted from a server modem to a client modem during a plurality of DIL levels. Both signature analysis and signal level comparison analysis are preformed on the signals to identify digital impairments. Signature analysis compresses the set of signal levels into a signature. Digital impairments are determined based on the signature. In a preferred embodiment, the PCM signal levels are compressed into a signature by identifying clusters and/or skips. PCM signal level comparison analysis uses differences, between PCM signals and models of signals having various digital impairments. By using both techniques combination, the strengths of each technique are utilized while the weaknesses of each techniques are avoided.

摘要： Methods, systems and computer program products are provided for refining constellation values in a Pulse Code Modulated (PCM) code point sequence of a PCM modem by averaging received levels associated with received symbols for a code point of interest received during data mode operation of the PCM modem so as to provide an average received level for the code point of interest and revising a constellation value corresponding to the code point of interest in the PCM code sequence based on the average received level for the code point of interest so as to provide a refined constellation value. Preferably, the averaging is performed by detecting that a symbol corresponding to the code point of interest has been received by the PCM modem and incorporating the received level of the symbol into a running sum of previously received levels for the symbol. If a predefined number of received levels have been incorporated into the running sum then the running sum is divided by the predefined number of receive levels. It is also preferred that, after determining the sum for the code point of interest, the running sum is set to zero and a new code point selected as the code point of interest.

摘要： Modems, methods, and computer program products for recovering from errors during a tone reversal sequence between a modem pair detect a false tone reversal during a tone reversal sequence at a first modem. If a false tone reversal is detected, then the first modem requests that a second modem restart the tone reversal sequence. Tone reversal sequences are used, for example, in the startup protocols of both the V.34 and V.90 standards to calculate the round trip delay between two modems. Neither standard provides for any recovery procedure, however, should the tone reversal sequence fail. The modems, methods, and computer program products can allow errors in a tone reversal sequence to be addressed immediately rather than proceeding to later phases in the communication protocol where the errors may ultimately cause the communication session to breakdown.

摘要： A benchmark tester retrieves a voltage margin that corresponds to a device that a system includes. The voltage margin indicates an additional amount of voltage to apply to a nominal voltage that, when added, results in the device operating at a power limit while executing a worst-case power workload. Next, the benchmark tester (or thermal power management device) sets an input voltage for the device to a value equal to the sum of the voltage margin and the nominal voltage. The benchmark tester then dynamically benchmark tests the system, which includes adjusting the device's frequency and input voltage while ensuring that the device does not exceed the device's power limit. In turn, the benchmark tester records a guaranteed minimum performance boost for the system based upon a result of the benchmark testing.

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 packet network redistributes excess bandwidth for voice and data sessions applying a Quality of Service (QoS) algorithm. The network includes interacting client stations using H.323 protocol managing bit rate according to an algorithm as voice and data sessions are added or removed from the network. The client stations include codecs coupled to the network. The codecs provide voice sessions at a minimum bandwidth using a voice codec bit rate and preferred bandwidth using another voice codec bit rate. A first algorithm applies the QoS algorithm allocating bandwidth between interacting client stations after the addition of a new voice or data session when there is insufficient bandwidth for the new session to receive preferred bandwidth. A second algorithm is applied when a voice or data session is removed from the interacting client stations. If any session is allocated minimum bandwidth the QoS increases a voice session at minimum bandwidth to preferred bandwidth if excess bandwidth is available.

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.
