A block interleaver (610) for interleaving blocks of coded symbols comprises a 2-dimension word addressable DWA memory. An M-row-by-N-column array (610) of bit cells (300) is addressed by logic (242, 252) using 2-Dimension Addressing, using first and second orthogonal address spaces. The block interleaver accepts the coded symbols in blocks by filling the columns of the array, and outputs the interleaved symbols one row at a time. A corresponding de-interleaver, and ping-pong buffer (600) comprising an interleaver and de-interleaver, are disclosed.
