  • Publication number: 20080192631
    Abstract: A method of controlling a data flow, a transmitter and a data transmission system are described. For example, in a method of controlling a data flow of a transmitter, first data is received at a first interface. The first data is buffered in a buffer. The first data is output via a second interface. Information is determined regarding an estimated amount of second data comprising payload data output via the first interface until a filling level of the buffer will reach a predetermined threshold. An amount of the payload data output via the first interface is adjusted based on the information. The payload data is then output via the first interface. Similarly, a transmitter includes an interface to output payload data and a control signal, and a buffer to buffer further data received via the interface wherein the control signal controls a flow of said further data.

  • Patent number: 7346746
    Abstract: A system with multiple processors sharing a single memory module without noticeable performance degradation is described. The memory module is divided into n independently addressable banks, where n is at least 2 and mapped such that sequential addresses are rotated between the banks. A bank may be further divided into a plurality of blocks. A cache is provided to enable a processor to fetch from memory a plurality of data words from different memory banks to reduce memory latency caused by memory contention.

  • Publication number: 20080065969
    Abstract: A system for processing a data signal (such as an ADSL or VDSL signal) includes a first decoder unit, such as a convolutional decoder or a QAM decoder, for receiving the data signal, decoding the second level of encoding and outputting a decoded signal and a first error indication signal indicative of errors in the decoded signal. A redundancy decoder employs the decoded signal and the first error indication signal (or transformed versions thereof) to perform redundancy decoding.

  • Publication number: 20080065968
    Abstract: A system for processing a data signal (such as an ADSL or VDSL signal) includes a demodulator, a first decoder unit, such as a convolutional encoder or a QAM decoder, for receiving the output of the demodulator, decoding the second level of encoding and outputting a decoded signal and a first error indication signal indicative of errors in the decoded signal. The decoded signal is passed through a de-interleaving unit to form a de-interleaved signal. The first location signal is passed to an identifier unit which receives it, and from it produces a second error indication signal indicative of the errors in the de-interleaved signal. The de-interleaved signal and the second error indication signal are transmitted to a redundancy decoder which employs them to perform redundancy decoding.

  • Publication number: 20080008255
    Abstract: A discrete multitone (DMT) transceiver communicates with multiple channels generates and receives DMT symbols each having a duration of a timeslot. A transmitter portion of the transceiver includes a symbol processor which generates symbols for multiple channels sequentially, and stores the generated symbols in a buffer until they are transmitted. A receiver portion simultaneously receives symbols on multiple channels and stores the symbols in a buffer, from which the symbols on different channels are read and processed sequentially. To reduce the rate of communication on a given channel, the symbol processors may be idle in respect of some of the timeslots corresponding to that channel. The transceiver may alternatively be an OFDM transceiver.

  • Publication number: 20070276833
    Abstract: System and method for assignment of unique identifiers in a distributed environment. In a distributed system having a plurality of nodes, a method for allocating identifiers comprises steps of: allocating a pool of identifiers for use; maintaining lists of free identifiers in the pool at participating nodes; obtaining at a first node permission to update the lists of free identifiers; upon receiving permission to update the lists, allocating for the first node a set of identifiers from the lists; updating the lists of free identifiers to reflect allocation of the set of identifiers for the first node; sending the updated lists from the first node to other participating nodes; upon receiving the updated lists of free identifiers at each other participating node, updating each other participating node's respective copy of the lists of free identifiers; and relinquishing the first node's permission to update the lists of free identifiers.

  • Publication number: 20070234292
    Abstract: In an application executing in multiple computers connected by a network, an instance of the application is deleted from a group of instances that share a resource, such as a database. Specifically the to-be-deleted instance is shut down, followed by deleting connectivity between the to-be-deleted instance and the network, and then deleting an object of the to-be-deleted instance. Each of these acts is performed automatically without user input, once the user issues an instruction to delete the to-be-deleted instance.

  • Patent number: 7203700
    Abstract: A new instance of an application is added to a group of existing instances (of that application) that share a resource, such as a database. The new instance is added by creating a new object for the new instance by cloning an existing object of an existing instance in the group, setting up connectivity between the new instance and a network through which the multiple instances communicate with one another, and starting up the new instance. The just-described acts are performed in the reverse order when deleting an existing instance. Each of these acts may be performed manually, or automatically without user input, with the user issuing at least one instruction to add or delete an instance.
