Abstract: A method is provided for propagating clock signals in a circuit segment having a first clocked device, a second clocked device and a data path between the first clocked device and the second clocked device. The data path propagates data released by the first clocked device to the second clocked device and is associated with a data propagation delay. The method comprises providing a clock propagation path for propagating clock signals to the first clocked device and the second clocked device, wherein the clock signal propagated to the second clocked device is delayed from the clock signal propagated to the first clocked device by a clock delay interval, the clock delay interval being related to the data propagation delay of the data path. A circuit segment making use of the above method is also provided.

Abstract: A method and apparatus for reducing echo in a communication system are provided. A first signal including a voice component associated to a speaker is received. The first signal is processed to derive a harmonic feature of the voice component. A second signal including an echo component correlated to the first signal is also received. The second signal is processed at least in part on the basis of the harmonic feature of the voice component to remove at least in part the echo component such as to derive an echo reduced signal. The echo reduced signal is then released. In specific implementations, the harmonic feature of the voice component is an estimate of the pitch associated to the voice component.

Abstract: 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.

Abstract: 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.

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.

The selected set of filter coefficients is then released in a format suitable for use by an adaptive filter.
