Abstract: Techniques are disclosed relating to circuitry configured to interleave data, e.g., for use to process error correcting codes for wireless data transmission. In some embodiments an apparatus includes one or more circuit elements configured to receive input data samples, a plurality of polynomial coefficients, a start index, and information indicating a window size for non-sequential traversal of interleaver indices. The polynomial coefficients may include coefficients for at least a third-order polynomial. In some embodiments, the one or more circuit elements are further configured to generate interleaved bank and address information for writing the input data samples to the plurality of memory blocks, based on an order of the polynomial, a code block length, the start index, and the information indicating the window size. In some embodiments, the apparatus also includes output circuitry configured to provide interleaved data samples from the memory blocks.
