Abstract: A semiconductor device comprising processing logic. The processing logic is arranged to configure interleaver logic to re-order data symbols of a data stream according to a quadrature permutation polynomial function. The processing logic is further arranged to: divide a cyclic group of values defined by the QPP function into a set of subgroups, the set of subgroups being capable of being defined by a set of linear functions; derive inverse functions for the set of linear functions defining the subgroups; and configure the interleaver logic to load the data symbols of the data stream into a buffer at locations within the buffer corresponding to a cyclic group of values representative of the inverse function for the QPP function based on the inverse functions of the set of linear functions defining the subgroups.

Abstract: A method for generating an interleaved output during a decoding of a data block, the method includes: (i) selecting, in response to a row indicator, a row register and a multiplication factor to provide a selected row register and a selected multiplication factor; wherein the selected multiplication factor is responsive to a size of the data block; (ii) multiplying a value stored in the selected row register by the selected multiplication factor to provide an intermediate result; (iii) performing a modulo P operation on the intermediate result to provide a permutated result; wherein the permutated result and the value stored in the selected row register are adjacent elements of the same permutation; wherein P is responsive to a size of the data block; (iv) writing the permutated result to the selected row register; and (v) outputting a data block element that is selected in response to the permutated result.
