  • Patent number: 7840781
    Abstract: Various approaches for profiling a target system are described. In one approach, a uni-directional, point-to-point bus has a single input port and a single output port. A target processor has a trace port coupled to the input port of the bus and is configured to execute a plurality of instructions one or more times. The target processor provides state data at the trace port and to the input port of the bus. A profile circuit arrangement is coupled to the output port of the first bus, and a memory is coupled to the profile circuit arrangement. The profile circuit arrangement is configured to read data from the output port of the first bus and write the data to the memory.

  • Patent number: 7802165
    Abstract: Systems and methods for processing data signals are described. In one implementation, a demodulator and a first decoder unit, such as a convolutional encoder or a quadrature amplitude modulation 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 are provided. The decoded signal may be passed through a de-interleaving unit to form a de-interleaved signal. The first location signal may be 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 may be transmitted to a redundancy decoder, where the signals may be used to perform redundancy decoding.

  • Patent number: 7796699
    Abstract: A new protocol is proposed for transmission of data through lines such as telephone lines. The tones of a signal are associated into groups 10, 11, and tone ordering, gain selection, and/or bit swapping within the processing system are done within the members of a group 10, 11. This idea is applicable both to tone ordering etc., following the training stage, and also to the dynamic configuration changes subsequently, for example, bit swapping. The computational cost of coding and decoding the data is reduced (compared to treating all the tones of a given direction equivalently), and the invention makes it possible to significantly reduce the memory requirements of the encoder and decoder.

  • Publication number: 20100106722
    Abstract: A method and system for description of synthetic audiovisual content makes it easier for humans, software components or devices to identify, manage, categorize, search, browse and retrieve such content. For instance, a user may wish to search for specific synthetic audiovisual objects in digital libraries, Internet web sites or broadcast media; such a search is enabled by the invention. Key characteristics of synthetic audiovisual content itself such as the underlying 2d or 3d models and parameters for animation of these models are used to describe it. More precisely, to represent features of synthetic audiovisual content, depending on the description scheme to be used, a number of descriptors are selected and assigned values. The description scheme instantiated with descriptor values is used to generate the description, which is then stored for actual use during query/search.

  • Patent number: 7688728
    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: 7617218
    Abstract: A system and techniques are described for managing key-value pairs using an architecture that does not restrict its users to any specific platform or storage subsystem. According to one aspect of the invention, the repository is portable in that the architecture need not change based on the environment and platform in which the repository is used. Rather, the portion of the architecture that is platform-specific is limited to plug-ins at a storage abstraction layer of the repository. The plug-ins expose the same storage abstraction interface to the other layers of the repository, but are implemented to interact with different platforms and storage subsystems. Consequently, in response to being ported from one platform to another, the repository may simply change the plug-in to invoke for persistent storage operations.
