摘要： An acoustic echo cancellation device for generating a pseudo echo signal by filtering an input remote speaker signal based on a plurality of adaptive filters and controlling the adaptive filters to filter the same based on a filter coefficient. The acoustic echo cancellation device generates an error signal by subtracting the pseudo echo signal from a nearby speaker signal, determines a convergence state of the filter coefficient based on the error signal, and sets at least one filter coefficient with a previously used value to stop the operation for calculating new values for the corresponding filter coefficients when the filter coefficient is determined to be converged.

摘要： A direct memory access controller (DMAC) for improving data transmission efficiency in multi-media over internet protocol (MMoIP) and a method therefor are provided. The DMAC requests and obtains a bus control right by determining that a DMA request signal is generated not only when a DMA request signal of a module for processing data in MMoIP is received but also when an operation of a timer operating during a predetermined period set considering periodicity of data in MMoIP is completed. Thus, the time taken to request a bus control right in a conventional DMAC can be reduced, thereby improving data transmission efficiency in MMoIP.

摘要： A codec platform apparatus which can perform encoding or decoding regardless of a sampling frequency supported by a codec platform is provided. The codec platform apparatus includes an analog-to-digital converter (ADC) converting an analog input signal into a digital signal by sampling the analog input signal at a codec platform sampling frequency; a sampling frequency converter converting the digital signal provided by the ADC into a digital signal having a codec sampling frequency; and an encoder generating a bit stream by compressing the digital signal provided by the sampling frequency converter. Since there is no need to adopt a new codec platform even when an existing codec platform does not support the sampling frequency of a new codec, there is no need to implant the new codec. Therefore, it is possible to improve user satisfaction.
