ABSTRACT:
A real-time sample rate converter having a non-polynomial convolution kernel provides reduction in die area and power for performing sample rate conversion in real-time. A non-polynomial convolution kernel, which may be a gaussian operator, is used to determine output sample values from values of an incoming stream of values. If the input sample rate is higher than the output sample rate, the input sample stream is convolved with the gaussian kernel and then decimated to yield the output stream. If the input sample rate is lower than the output sample rate, the input stream is resampled to a small multiple of the output sample rate and convolved with the gaussian kernel to produce the output sample stream directly.
