Abstract

Systems and methodologies are described that facilitate automatically generating interleaved addresses during turbo decoding. An efficient recursive technique can be employed in which layers of nested loops enable the computation of a polynomial and a modular function given interleaved parameters “a” and “b” from a look up table. With the recursive technique, interleaved addresses can be generated, one interleaved address per clock cycle which can maintain turbo decoding performance.
