ABSTRACT:
A first grouping of memory space addresses is generated for systematic bits of a received codeword; a second grouping of memory space addresses is generated for a first set of coding bits of the received codeword, wherein the first set of coding bits comprises an ascending order; and a third grouping of memory space addresses is generated for a second set of coding bits of the received codeword, wherein the second set of coding bits comprises an interleaved order. A sub-codeword of the received codeword is decoded in parallel by accessing the first set of coding bits using the addresses in the second grouping of memory spaces. In turn, another sub-codeword of the received codeword is decoded in parallel by accessing the second set of coding bits using the addresses in the third grouping of memory spaces. Apparatus and a memory storing a computer program are also detailed.
