摘要： A mechanism controls a multi-thread processor so that when a first thread encounters a latency event for a first predefined time interval temporary control is transferred to an alternate execution thread for duration of the first predefined time interval and then back to the original thread. The mechanism grants full control to the alternate execution thread when a latency event for a second predefined time interval is encountered. The first predefined time interval is termed short latency event whereas the second time interval is termed long latency event.

摘要： A method and structure is disclosed for dispatching appropriate data to a network processing system comprising an improved technique for extracting protocol header fields for use by the network processor. This technique includes basic classification of a packet according to the types of protocol headers present in the packet. Based on the results of the classification, specific parameter fields are extracted from corresponding headers. All such parameter fields from one or more protocol headers in the packet are concatenated into a compressed dispatch message. Multiple of such dispatch messages are bundled into a single composite dispatch message. Thus selected header fields from N packets are passed to the network processor in a single composite dispatch message, increasing the network processor's packet forwarding capacity by a factor of N. Likewise, multiple enqueue messages are bundled into a single composite enqueue message to direct enqueue and frame alterations to be taken on the bundle of N packets.

摘要： A page table mechanism translates virtual addresses to real addresses. In a first aspect, page table entries are contained in equal-sized blocks, the entries within each block corresponding to contiguous pages of virtual address space. Preferably, the common high-order portion of the virtual address is contained in segments distributed among multiple page table entries of the block. In a second aspect, the virtual address indexes a binary tree definitional structure. Decode logic traverses a binary tree defined by the definitional structure by testing selective bits of the virtual address to reach a leaf of the binary tree, which defines the location of data defining the real address.

摘要： Methods, systems and computer program products are provided for monitoring performance of a modem which obtain diagnostic data directly from memory associated with the modem's digital signal processor (DSP). A secondary path to the DSP memory is utilized for the monitoring operations so that real time data can be obtained during connection startup procedures and during an active connection. First-in first-out (FIFO) buffers are incorporated in the DSP memory to track state transitions of one or more of the state machines within the modem and various performance data measurements may be obtained directly from the DSP memory responsive to different state transition events. The real time collected data may be stored in a file and provided to a remote location for use in diagnosing customer problems with specific customer line connections. Accordingly, real time monitoring of digital and analog line conditions and modem performance may be utilized to diagnose problems with modems and line connections.

摘要： A method and structure for performing a delayed counter increment is provided. The method and structure allows a counter decision to be modified based upon what the computer system hardware does with the data packet. Subsequent to the generation of a counter command, the processing of the data packet may change: for example, the data packet may be discarded instead of forwarded. Accordingly, the counter increment instruction is changed. A delayed counter increment will perform the actual counter update after the processing of the data packet is completed. In one embodiment of the invention, the counter update action is modified depending upon whether the data packet is forwarded or discarded, and a different counter is selected to be updated. This solves a problem that sometimes the forwarding code is unable to determine if some independent action may later discard a data packet.

摘要： Methods, systems and computer program products are provided for constellation generation which determine initial ucode boundaries and an initial minimum signal level spacing. A work constellation set is generated based on the initial ucode boundaries and the initial minimum signal level spacing. The work constellation set is then iteratively adjusted so as to provide an adjusted work constellation set which achieves an error probability target. The adjusted work constellation set is then iteratively pruned so as to provide a pruned work constellation set which achieves a power limit. The pruned work constellation set is then iteratively fine-tuned so as to provide a final constellation set which is within a specified tolerance of the error probability target and/or the power limit.

摘要： Modems, methods, and computer program products select a data rate based on error signals in a modem. In an illustrative embodiment, error signals representing the difference between an output of an equalizer and an output of a detector are accumulated and an average error value is computed therefrom. A signal to noise ratio is determined using the average error value. The signal to noise ratio is then used to select a data rate. In another illustrative embodiment, the mean squared error at the output of the equalizer is determined and then used, along with the probability of error in correctly detecting a symbol, to select a data rate. Incorrect decisions in detecting received data symbols can cause a catastrophic failure in a decision feedback equalizer used in a modem receiver as errors are repeatedly fed back causing the tap coefficients for the equalizer filters to be shifted from their normal operating values. By adjusting the data rate in accordance with the error signals generated in a modem receiver, the decision feedback equalizer can operate with greater stability as the data rate can be reduced in response to increased noise conditions.

摘要： Severe error detectors, methods, and computer program products use constellation specific error event thresholds to detect severe error events in a signal comprising symbols from a plurality of symbol constellations. In particular, a plurality of constellation thresholds are defined that correspond to a plurality of symbol or signal constellations. An output signal sample, which is associated with one of the plurality of symbol constellations, is received from a decision feedback equalizer. The absolute value of the output signal sample is compared with the constellation threshold that corresponds to the particular symbol constellation associated with the output signal sample. If the absolute value of the output signal sample exceeds the constellation threshold, then a severe error is recognized. The ITU V.90 Recommendation allows up to six different symbol or signal constellations to be used in the same communication session. The multiple constellations may be designed such that an error threshold suitable for one constellation may not be suitable for another constellation. As a result, a severe error detection circuit or module using a single constellation threshold for detecting severe errors may either under report or over report severe error events. Advantageously, multiple constellation thresholds may allow severe errors to be detected with greater precision than could be detected using a single constellation threshold.

摘要： A method and system in a data processing system are disclosed for the retransmission of only a portion of a data packet which had originally been transmitted incorrectly. A first data link is established between a first computer system and a second computer system. In response to the establishment of the first data link, a second data link is established between the first and second computer systems, whereby the first and second data links are related. A plurality of data packets are transmitted from the first computer system to the second computer system utilizing the first data link. Each of the data packets includes a plurality of segments. A determination is made whether each of the plurality of data packets is received correctly. In response to a determination that one of the plurality of data packets is received incorrectly, a portion of the data packet which was transmitted incorrectly is determined. Only the incorrectly transmitted portion of the data packet is then retransmitted by the first computer system utilizing the second data link.
