摘要： A method is provided for interfacing a plurality of processing components with a shared resource component. A token signal path is provided to allow propagation of a token through the processing components, wherein possession of the token by a given processing component enables the latter to conduct a transaction with the shared resource component. Token processing logic is also provided for propagating the token from one processing component to another along the token signal path, the propagating being done at a propagation rate that is related to a transaction rate associated with the shared resource component. The token processing logic also generates a trigger signal at least in part based on the token and propagates to trigger signal to the shared resource component to convey initiation of a transaction with the shared resource component. A circuit comprising a plurality of processing components and a shared resource component is provided wherein the plurality processing components and the shared resource components are interfaced with one another using the method proposed.

摘要： An apparatus and method suitable for producing a set of filter coefficients are provided. Sequences of samples of first and second signals are received by the apparatus. Each received sample is processed to update a set of auto-correlation data elements and cross-correlation data elements. The set of auto-correlation data elements corresponds to a compressed version of a corresponding auto-correlation matrix data structure. A scheduling controller generates a scheduling signal including a succession of scheduling commands, the scheduling command indicating that a new set of filter coefficients is to be computed. A new scheduling command is issued when at least two samples of first and second signals are received subsequent to a previously issued scheduling command. In response to a scheduling command, the auto-correlation data elements are processed to generate the auto-correlation matrix data structure. The auto-correlation matrix data structure and the cross-correlation data elements are processed to generate a set of filter coefficients by applying a least squares method.

摘要： A filter adaptation unit for producing a set of filter coefficients indicative of a transfer function of a system in a given state is provided including a coefficient set selection unit for selecting between two or more sets of filter coefficients. For each set of filter coefficients a respective set of error characterization data elements is generated characterizing the error in a filter's impulse response when using the corresponding set of filter coefficients. The selection unit provides functionality for processing the first and second sets of filter coefficients and the second set of error characterization data elements in order to detect whether a change in the state of the system has occurred and to select a preferred set of filter coefficients. The selected set of filter coefficients is released in a format suitable for use by an adaptive filter. A method and apparatus selecting a set of filter coefficients from a plurality of sets of filter coefficients is also provided, where each set of filter coefficient is associated to a segment of a first signal. The sets of filter coefficients are compared to one another to select at least one set of filter coefficients from the plurality of sets of filter coefficients at least in part on the basis of energy values associated to impulse response of the plurality of sets of filter coefficients.

摘要： A device and method for generating a set of filter coefficients is provided. Sequences of samples of a first and second signal are received where the second signal includes a certain component that is correlated to the first signal. A first set of filter coefficients is generated on the basis of the first and second signals. A set of performance data elements are generated to evaluate the performance of a filter using the first set of coefficients, each performance data element being associated to a respective frequency band selected from a set of frequency bands. Following this, a set of correction signals is generated including a correction signal for each frequency band for which the associated performance data element is indicative of an unsatisfactory performance. A second set of filter coefficients is generated on the basis of the first signal, the second signals and the set of correction signals. The second set of filter coefficients is then released in a format suitable for use by a filter.
