  • Publication number: 20230198506
    Abstract: Systems, devices, and methods related to a sample rate converter (SRC) for implementing a rate conversion R are provided. The SRC receives input samples at an input rate Fin and outputs samples at an output rate Fout=Fin×R, where R is a fractional value greater than 1. The SRC includes a plurality of filters to process the received input samples and a multiplier-adder block to generate the output samples based on respective delta values and outputs of the plurality of filters. The SRC further includes a plurality of buffers to buffer samples between the plurality of filters and the multiplier-adder block based at least in part on N buffer read pointers, where N is an integer greater than 1. The SRC further includes resampler control circuitry to generate N delta values of the delta values and the N buffer read pointers in parallel based on R.
